Hey Louis and Dave, I own a rework/solder station and have the same issue with flickering (fluorescent) lights in my workshop. I did some investigating with a power meter and in my case at least it is caused by the logic board modulating the heating element on/off in short pulses once it is up to temperature to keep it at temp. Taking the heater off the stand also causes my lights to dim, placing it back in the holder fixes that issue immediately (while the fan is still cooling it down). The entire workshop is on one breaker, separating the lighting from the outlets at the breaker panel should solve the issue.
yea right they would do all talk no work like always... these dudes everyone look up to need to learn better soldering skills they are both horrible with soldering iron imho.
Louis Rossmann is what you'd call a straight shooter. Super detailed repair videos and the occasional random life lessons. Definitely worth subscribing.
Misty Moo Not everybody likes to beat around the bush (even when it's completely unnecessary, useless and even counterproductive) all their lives you know....
Ollie B why do you care so much if we are not worth. too much drama and nothing real to learn or gain from his content. just a guy loves to listen to his own voice. and the real bullshit is trying to sell crap from youtube.
Really surprised to see a brushless motor in there. How would conducted or radiated noise cause lights to flicker? It's obviously just the current draw when the heater turns on & off
mikeselectricstuff Exactly, I have much weaker hot air station which does the same. It uses a TRIAC in leading edge phase fired controller circuit, which is the source of that flicker.
Yes, Louis needs to not run that on the same circuit as the lights. When I'm down in some old cellars doing my work with a 2kW hot air gun, the lights flicker like crazy. Old wimpy wiring and long runs from the breaker panel tends to do that to you.
Louis' advice: Wait for the chip to dance (move) before you remove it. I made the same mistake until I saw Louis do it. I have learned loads from his content You didn't seem to like the angle of the fan, even though you didn't criticize it. I think I see the method behind the madness of the designers. I think the placing of the fan enables it to suck cold air over the components that get hot before it gets heated and blown out of the nozzle at a PC board. Brilliant ingenuity. I take my hat off to them. It is always a pleasure to watch somebody who knows what he is talking about, and it is a pleasure watching you. Keep it up mate :)
I bought one of these soon after Louis's review. It is indeed very good. Compared to my existing rework station no contest for desoldering large components and BGA's and such there's simply no contest. Also Louis, is a great channel. He's a good guy and for someone who's much older than him I've gotten a few life lessons too. I like his cats too :)
Once again sir you hit on ALL the key points that allow me to justify purchasing a tool like this. So entertaining AND informative. Thank you again Dave! You are just flat out AWESOME!
Pretty sure Louis' issue is that a US circuit is only 15A @ 120V, so 1000W is a pretty good chunk of that. The big disadvantage of 120V and small (14ga / 2sqmm) wire. Not uncommon at all to see lights dip here in North America when a bit load is switched in
It could be, but a JBC JT-A at full power causes zero flickering. Maybe the Quick is more powerful, but I don't think it is *that* more powerful. As much as I love my Quick I have to acknowledge that the $1200+ price difference comes from cheaping out on the power supply.
Boffin A typical 120V US circuit may be either 15A (1800W, #14 copper minimum) or 20A (2400W, #12 copper minimum), both are quite common though in very old structures the 15A circuit was much more typical since in the first half of the 20th century a typical household load consisted of lights, a radio, later a TV, and the occasional clothes iron or vacuum and that was about it outside of the kitchen. However, the tendency towards flicker really depends a lot upon where in the AC cycle the heating element is being powered on. I would imagine they are using a random phase triac driver, which means you can be switching on a high powered heating element right at the AC peaks with fair regularity and if your circuit is already loaded down or has a fairly long run back to the mains panel then you can get noticeable flicker, particularly with fluorescent and LED lighting. You might well be able to get away with swapping the random phase triac driver for a zero-crossover driver and resolve the flicker issue so long as long as the temperature regulation loop is not adversely altered.
The light flickering is probably from the 1000W heating element being switched on and off. My $40 chinese reflow station does it, as well as my laser printer and laminator.
I have one of the youyue 858D reflow stations. It works fine for hobby use. Just be sure to check that the ground and the fuse is wired correctly if you get one.
Check the optocoupler that drives the triac of AC heating element to see if is a zero cross type rather than a random phase that placed by mistake and causes the room light flickering.
Hot air was one of my special skills!! Pre-heat bed and hot air gun and I could rework QFD devices, and BGA devices by hand, and I was tagged as the "expert" in my group. It can be a really really TRICKY skill! SOT packages, 0201 SMDs, of course 0402, 0603 and larger got to be a piece of cake.
I bought one on the advise of Louis, really a great product. I was following Dave some years before Louis, i'm glad to see this review on this product from Dave too.
The trick with these is the careful application of heat and not damaging all the surrounding parts. I generally pre-heat the whole board slowly before going for the lift. I also have high temp silicon sheets that I use to mask the target area. It does no good if you damage the PCB or other components. Liquid or gel flux is critical IMHO.
I love Louis 's channel, great life lessons and lessons on board level smd repair work all round. ......... also time is money, the quick 861DW will earn back itself in a week if you are a professional.
I doubt it would integrate with Louis' Open Broadcaster software as tidily as his usual DMM does, and Louis is many things but I don't think he's got the patience to program a connector :-)
It's quite common for these stations to "hide" bad temperature regulation and give you a nice, round reading as long as the temp. is inside a small window :)
Same with cheap chinese scales. They're good value for the price, but absolutely not in the professional instruments league. I can't imagine that someone would seriously suggest this as equipment in real lab :-)
Quick seems to be well distributed in Poland. I had to buy mine from there to France for around 250€. There was other offers in Europe but not for the beefier 861DW variant.
400C at full airflow seems a bit excessive but I can't fault the speed, especially for the big FETs. I've used whatever hot air station Sparkfun sells before but this one definitely seems worth the added cost.
I bought an 858D. But I bought it only for heat shrink tubing. I’ve got some good guns, but for smaller wires and such, they’re too big and overkill. Never tried it on surface mount components. It does come with several sizes of nozzles. The temp setback does work. Also, I got it on eBay for a bit over $40, shipped. Seriously, for $40, it’s pretty good. This model is available from a number of different vendors with the same, or similar look, with different names.
When you turn the holder around, you can pull the nozzle and have it cached in the cup. What for not having hot metal things rolling all over your bench. ;)
I think if you put a scope on the heater you would see it switches fairly slowly, that causes the lights flickering... just the branch circuit voltage drop due to the heater load. I get lights flickering with a temp controlled heat gun when the lights are on the same breaker. Louis probably has the same thing, needs isolated circuits for lighting vs high power equipment. But, as a renter, doing electrical upgrades is just donating $$$ to the landperson...
This right here. I have a different SMC rework station and when it switches the heater on/off it causes heavy voltage drop on the bench circuit, sometimes fast enough to get a nice flicker going on the bench lights. It is far worse on a 110v system with that 1kW load.
micksam7 Bingo. It’s brutal on a normal 110v circuit with any other load on it. It does proper zero-voltage AC chopping (watch Louis’s teardown; they get the scope on it. It switches just like the Hakko or any other high end unit, it’s just much higher current) and basically everything else right, but there’s only so much it can do with weak sauce US mains circuits.
Probably someone already commented on this, but it seems there are two models, the 861DW and the 861DE. The DW only goes to 120 l/min and the DE is the one that goes up to 200 l/min. So the display is actually indicating the air flow in l/min.
The motor may look 'wimpy' but you'd be surprised how much power a small brushless motor can deliver. For a robotics project we used a brushed motor of about 15W to drive a dribbler system to move a ball. This motor was replaced by a tiny brushless motor from maxon motors (i believe it was the EC max 30) which was just 30mm x 62mm, a lot smaller than the original 15W brushed one, yet put out an incredible 60W of power.
This is the actual motor used; www.wonsmart.com/English/Product/0586241350.html It's a torquey little brute, 17,000RPM unloaded speed, 8K full load delivering a max torque of 58 mN-m. Real ball bearings. 3 hall effect sensors, 3 phase. 110-ish watts under full load. Very narrow and light spinning mass for ease of balance and quietness. Excellent choice. Not a cheap motor either,.
True, for quality motors you have to spend big bucks, but its worth it. Next to clearly better performance and being quiet, they last a loooot longer in my experience.
Hi great video. Switching between Celsius and Fahrenheit can be achieved by pressing both the ch2 and ch3 buttons for 3 seconds. (Sound can be toggled on/off by pressing ch1 and ch3 for 3 seconds)
@@mitchcm that's a bummer! I've never used the 881d. I only have the 861d model. (Also I wrote my original comment wrong; it is ch1 and ch2 to toggle sound)
I also have this Quick Station. There is nothing in this price range that can compare. Hakko and Weller is almost 3 times the price of the quick. I have mine for almost half an year and I'm still very impressed. Unfortunately mine has a "beeping" noisy motor with high frequency sound -.- but beside of that if you searching a hot air station right now. There is no way around the quick
One correction, airflow on the DW model is only 120 (like it says in the display). The DE model of the 861 series is a 200 L version (and 1200 watts instead of 1000 on the DW). And on the DE the LCD setting goes to 200 (as expected).
32:11, not You mistake, just use FLUX easy to remove after desolder process and vacuum tweezers to lift big BFA chips. Good to use termo sensor and best way to use preheater set to 100-150 st C. No to fast heat or internal silicon can crack.
@@nombinator lol not sure how the nation that invented the grid has an odd custom voltage relative to later adopters. As for less subjective I seem to recall 50hz is a bitch for motors. Having watched enough LR I'd guess he chose to use recycled soda cans instead of copper wire 😂 220 easier to get a lethal hit from too no? Simple i=e/r
@@johnw1385 240v means lower current for the same power, less voltage drop for a given conductor size or cheaper conductors for a given voltage drop. Fatalities in modern GFCI protected installations are very rare.
I'd guess the flickering lights is from the heating element. When it's cold from being off or cooled down from being in the rest, it's going to surge the element at full power to bring the heat up as quick as possible, then likely PWM the power to the element to maintain heat. I see the same with my cheapo heat gun like the one you have. My entire bench is on an APC 1500va SmartUPS. When the heat gun 1st comes in it nearly maxes out the load the UPS can take for a few seconds, then it levels out to a much lower power draw depending on the temperature set
QUICK 861DW professional mobile phone repair and repair station, using brushless vortex fan, adjustable air volume, wide range, can be used for a variety of purposes. The system has the function of automatic cooling of air volume, which prolongs the life of heating elements and protects the hot air handle.
Dave, shouldn't that stand be used the other way around? Both for the attachment removal (so the attachment falls into the cup below) and for the weight of the cable pulling the hot air iron into the stand instead of pulling it off of it like in the video at 4:50. 🧐
Hall Effect type thing. I inherited mine without the stand so was unaware they auto switch off when in a stand. Drove me nuts while trying to replace the voice coil on a big woofer. Damn thing kept turning off when ever I brought it near the speaker. Had me stumped for awhile.
I bought a Quick 861DA about 8 weeks before Louis got his... i'd been deliberating on it for weeks. Glad I made the right choice. Wholly justified by your review too Dave. Odd thing is I get the same light flicker as Louis.. keep up the good work :)
Questions, would the fact that it is higher temp inside of the Nozzle have anything todo with the loss of heat as the air travels to the component? I am looking at get a rework station. Never used one.
Compare Quick 861DW with Best BST-863, and with NT 762E, low price product to one category. Quick 861 DW and Best BST863, inside the same, the parameters are the same, but the price is lower twice at BST 863. Do a comparative review.
As for hacking it, I have replaced the firmware of a solder station with proper PID control as well as zero cross switchin on the triac. Also display of the real temperature vs. the set. Note that afaik the atten shows the real temperature only when it is in power down mode, when it thinks its up to temperature it never shows any overshoot, but when you then put it down, it suddenly does. Regarding the loctite on the ground screw, I have seen some where this caused it to have no contact as it crawled in between.
The quick uses a remarkably well-tuned PID for temperature control. Dave's experimental methodology (sort of vaguely stuffing a thermocouple bead into the nozzle) is, well, poor. I set up a proper jig to hold the handpiece with the thermocouple in free air 5mm from the nozzle outlet so I could test/offset it properly shortly after I got it, and aside from the time taken to bring the nozzle up to temperature, the output is astonishingly accurate. Within ~5 degrees for the whole range, getting more accurate as the temperatures got hotter (up to the limit of my thermocouple anyway) So when he says 'it must be lying about temperature, it can't be that stable' I believe he is mistaken.
All reviews said cheap blower not so good and only for ocasional work, but thats what i needed so i bought it for 50 dolars. Impressive, especially for the price. Now your review is first where i see how capable cheap one is. True its slower, but with so much headroom on the temp i dont bother i will be needing more expensive any time if ever. And one if best parts with my cheap station is it stacks perfectly with my other tools!
It's just like most tools and equipment, the more you use something, the more you can warrant spending on it. I think the cheapi would be adequate for most hobbyists but obviously the one that's 4 times the price is going to be better
I came here to see the 858d in action because I just bought one and wanted to know how it would stack up against a professional machine. Thanks for the video. It really helped and I think I can do my amateur stuff with the 858d just fine. I just need to be a bit more patient. Great stuff!
Not even watched it yet, but thank you Louis been waiting for this since he mentioned he sent you one. I have been trying to get a filter right to kill the feedback that messes with the lights since I got mine.
I got mine QUICK 861DW a few days ago. For my unpleasant surprise, the airflow controll on this brand new unit seemed to be stuck on max. level. If I went below 112, the fan just stopped and a few beeps later it showed "ERR" message on the display. Upon closer inspection of the motor driver board, I noticed that the R59 timing resistor is simply missing. Since my attempts to measure the value of the C53 were unsuccesfull, I just assumed it to be 10nF. According the MC33035DW datasheet, fig.1, with 10nF cap @ 25khz, the timing resistor should be around 4,7k. so I teporarily soldered one in between pins 8 and 10, and voila...no more error messages and the airflow controll appears to be working just fine too. But just in case, could someone please look at the original value of the R59 on the motor drive board and post it here?? thanks very much...
The Atten cost me around $39 American. Same experience, but Atten is adequate, and it's good for for heat shrink, and heat polishing acrylic for DIY light pipes.
at 26:00 - you would've been less than 27 seconds as shown at 27:00 because you weren't heating up the rear pad... the solder on the side did become liquid, and then you focused on the front instead of more in the rear. It probably would've done better if you hung around the large pad more because when you started getting area hitting it from that side it came right off.
Hello, you seem very knowledgeable of this product. I have this station as well and it's no longer heating properly. I replaced the heating element, and it did not fix it. It's barley heating at all. What is the most likely part that's causing it to not regulate the temp?
Here's my thinking.... You set the minimum temperature needed for the desolder and then adjust the power/speed with airflow, since the the heating power carried by the airstream is depended on temperature and airflow on equal proportion.
Radiated switching will also be highly unlikely as the unit uses MOC3041 to drive the Triacs and that is a ZVC Opto Coupler for the heater. Having watched Louis' video, The Hakko also created flickering so I would have a serious look at the mains wiring. High loads on his mains seems to cause the issue. Just my 2c worth.
I'm not sure if I'm a fan of the CH1, CH2 and CH3 buttons, I'd prefer maybe a left/right or up/down cycle button to switch between presets stored in flash. That way you could have many more presets.
I was using a heat gun in my server room to test some temperature alarm points and noticed the lights flickering too, I think it's because these type of devices just modulate on/off instead of just adjusting the voltage to the element.
If I understand correctly the 1meg ohm resistor from line to ground, supposedly for noise is something which was done to audio equipment in the 1960s-1970s. It creates a live chassis situation. I'd snip that out.
You have misunderstood the video. This is a high value inline resistor used to safely ground the earth strap socket at the back of the chassis. It isn't connected to the live supply in any way.
When it gets hot those nozzles have a tendency to fall out I ended up drilling a small hole in the collar and tapping it to put a small screw to retain the nozzle
Yeah and he is moving the Atten ways more, he moves it all around the place while he keeps the Quick steady on the places needs to be heated up, that made all the difference: different nozzles and moving ways too much. I for my own expirience can say I like this Atten/Ayouye etc. around 10 bucks airgun ways more than all the ones with the blower inside the housing, I just hate those fat heavy tubes, the cheapos are ways more handy and for me they worked on changing smartphone parts ways better. Also Louis Rossmann is not god and free from failures, he is an image addict, all depends from the price, money has the most value for him, this is exactly what he is telling all the time, if you put a pile of shit on his table with a high price sticked into it, he also will say it's gold. Anyway, compared to the Atten, which costs up from 30€, the Quick is ways too expensive, just look inside it and you can count the prices for the single parts, I just can't get over 100€ for the parts plus the handpiece, stand and work its maximum 180€.
I’m not a fan of those hand pieces with the noisy blower in them. I prefer the blower pump inside the unit like the Aoyue which means the hand piece can be a bit smaller. But I agree the comparison to the Atten using a larger nozzle was unfair.
it's not meant to be fair... it's meant to show you the difference between a "good enough for 9/10 people" and "professional grade" so you can see whether its worth spending the extra money.
30% more power for 5 times the price, ...what happened to economies of scale? (Same goes for solder stations. Double the heat transfer for just 6 times the price?) This isn't like optimizing power to weight ratio of an engine, This is basically just a simple doubling [size or count] of the main power regulators the controls basically remain the same.
Type-K thermocouple can go from -270 °C to +1260 °C (www.thermocoupleinfo.com/type-k-thermocouple.htm), but it's just the metal wires, not the plastic insulation. So, at higher temperatures you can get the end of the insulation slightly burned, but the thermocouple will be OK and accurate.
honestly that temp memory feature on the quick is useful. I have an older cheaper model and switching between desoldering temps and lower temps for just melting stuff or shrink is a pain, many of times have I grabbed mine without thinking just to hit some heat shrink and its set at 400C
people also like the Quick 957DW+ for $113, only 580W and 100LPM air, some issues with transformer coming loose (vertically mounted-Doh!) but good if all together
Didn't used to be. Louis endorsed it and the price goes up. Soon it'll go for the same as a Hakko station. But, when you're buying tools, it's good to pay more and research thoroughly.
Just use any old heat-bed (kettle, whatever) and you will do everything with cheap hotair/soldering station. Temp. driver is a must, with some stm8 at least, ntc and relay, still cheap and effective. The other way is to preheat. Remember, both tools aren't complicated, at least chinese fan-fun won't blow your elements as you might expect from quick set too high with its flow.
At one-fourth the price, the Atten looks perfectly adequate for most home users. I would expect that a slightly smaller nozzle would concentrate the heat probably increase performance slightly.
Actually, gas soldering irons with the hot air tip can do the same especially good when repairing something in situ. A good example of this is the iroda solder pro with hot air attachment
I've used Aoyue 968 for the last 11 years. Had to replace the soldering iron part of the station, but as for that, it's been a trooper. My only complaint is there is some radio noise around 150Mhz and again at 155Mhz that interferes with my testing of radios. I usually have to program the radios to something else so it doesn't get interference.
Easy way to semi-bypass the RCD, (though is potentially dangerous in the wrong hands) disconnect the appliance earth and connect it to the neutral. (its still earthed via MEN) make sure you 100% check phase/neutral polarity. Any potential leakage to "real" earth will still trip the RCD, but current in the earth wire wont. handy for PAT testing on construction sites.
This sounds suicidal at best. In many (most) countries, there is no difference between live / neutral in mains wiring, it's just a convention with no practical importance. It's literally a 50/50 chance you'd be connecting earth to live.
Someone please explain how the same tempeature and max airflo rate can produce such dramatically different results. The math/physics suggests a variable that is beyond the machines; for the machines are delivering the same product = hot air :same temp :same max airflow rate... 3+4=7. What are the variables here that can account for almost 2x the time needed to get the solder to flow?
The flicker is a LOW FREQUENCY behavior. An EMI filter does not even start having any effect on it. I have had my battles with brush type DC motors commutation noise and the best EMI filters were only marginally effective, so I studied the things a bit. The first thing to realize is that all the filter characterization is done at 50 ohm in and 50 ohm out impedance. So, “your mileage is likely to vary”. Then the best filter I ever measured started its attenuation at 8 kHz. The commutation noise base frequency varies with the speed from nearly zero to some kilohertz. Only the harmonics get attenuated. A brushless drive produces its own corresponding commutation. The difference though is a lack of real sparks and thereby less harmonic and especially non-harmonic noise. As already stated, the low frequency variations causing light flicker is a different story. When the load current varies well below 50 or 60 Hz line frequency, you get voltage variation imposed to the power line due to the wiring size and length (resistance) and probably even more by the feeding transformer impedance (mostly inductance). As the movie industry found early on, the subjective flicker is really bad below about 25 Hz. So, they “cheated” by opening the projector shutter 3 times on each movie frame. Because SCR and Triac drives caused harmonic noise, some people designed mainly for temperature control systems that turned the heating on and off for half or full line cycles. And you can guess what happened: Huge flicker complaints, of course.
I just picked this up as a side fun project to learn. I can't seem to desolder smd leds for some reason. Either I'm not getting it hot enough or I am afraid of torching stuff..lol this is my first time and I have mulitple PCB's that are dead and just practice on. I can't seem to get the hang of it yet. I know how to solder normally but totally new to hot air rework stations.

Pretty sure Louis' issue is that a US circuit is only 15A @ 120V, so 1000W is a pretty good chunk of that. The big disadvantage of 120V and small (14ga / 2sqmm) wire. Not uncommon at all to see lights dip here in North America when a bit load is switched in
It could be, but a JBC JT-A at full power causes zero flickering. Maybe the Quick is more powerful, but I don't think it is *that* more powerful. As much as I love my Quick I have to acknowledge that the $1200+ price difference comes from cheaping out on the power supply.
Boffin A typical 120V US circuit may be either 15A (1800W, #14 copper minimum) or 20A (2400W, #12 copper minimum), both are quite common though in very old structures the 15A circuit was much more typical since in the first half of the 20th century a typical household load consisted of lights, a radio, later a TV, and the occasional clothes iron or vacuum and that was about it outside of the kitchen. However, the tendency towards flicker really depends a lot upon where in the AC cycle the heating element is being powered on. I would imagine they are using a random phase triac driver, which means you can be switching on a high powered heating element right at the AC peaks with fair regularity and if your circuit is already loaded down or has a fairly long run back to the mains panel then you can get noticeable flicker, particularly with fluorescent and LED lighting. You might well be able to get away with swapping the random phase triac driver for a zero-crossover driver and resolve the flicker issue so long as long as the temperature regulation loop is not adversely altered.
>cheaping out on the power supply
there is no power supply, heating element is directly switched to the mains
rasz exactly
Boffin Also it is an old NYC piece of shit building, probably just like 3 breakers for the whole place and 16awg wire
The light flickering is probably from the 1000W heating element being switched on and off. My $40 chinese reflow station does it, as well as my laser printer and laminator.
what reflow station do you have? do you recommend it for hobbyist? i dont have the 300$ to spend
Man my laser printer does! I can't believe how much current that thing sucks down when it's warming up. I'm surprised it doesn't trip a breaker.
I have one of the youyue 858D reflow stations. It works fine for hobby use.
Just be sure to check that the ground and the fuse is wired correctly if you get one.
Check the optocoupler that drives the triac of AC heating element to see if is a zero cross type rather than a random phase that placed by mistake and causes the room light flickering.
Hot air was one of my special skills!! Pre-heat bed and hot air gun and I could rework QFD devices, and BGA devices by hand, and I was tagged as the "expert" in my group.
It can be a really really TRICKY skill!
SOT packages, 0201 SMDs, of course 0402, 0603 and larger got to be a piece of cake.
Dave and Louis...Two of my favorites!
I bought one on the advise of Louis, really a great product.
I was following Dave some years before Louis, i'm glad to see this review on this product from Dave too.
The trick with these is the careful application of heat and not damaging all the surrounding parts. I generally pre-heat the whole board slowly before going for the lift. I also have high temp silicon sheets that I use to mask the target area. It does no good if you damage the PCB or other components. Liquid or gel flux is critical IMHO.
KAPTON TAPE FTW!
Kriss Olshaq I use Kapton tape as well, but I also rather like the idea of using silicone sheets, so I may have to give that a try one of these days.
I use piles of Kapton tape as well. The silicon, in many cases, is easier to just flop a strip or donut shaped piece on top.
I love Louis 's channel, great life lessons and lessons on board level smd repair work all round. ......... also time is money, the quick 861DW will earn back itself in a week if you are a professional.
I thought it was going to be yet another noisy aquarium pump hot air gun , but I'm surprised. It whooshes very well
First off. Shout out to Louis and Dave, both excellent youtubers in their respective categories!
Than you for sending Louis your multimeter. To bad he only used it 2 times on camera.
Hey, at least 3! :p I switched over to the B&K for the ability to see it on screen :)
Which one: the 121GW or the other one? 'Cause the 121GW has Bluetooth Data Logging, it would be a good substitute of the B&K
I doubt it would integrate with Louis' Open Broadcaster software as tidily as his usual DMM does, and Louis is many things but I don't think he's got the patience to program a connector :-)
PhilfreezeCH with an Open Broadcaster plug-in?
My 858D has held up for 3 years now its not bad for hobbyists i've used it a fair bit with no problems
It's quite common for these stations to "hide" bad temperature regulation and give you a nice, round reading as long as the temp. is inside a small window :)
its mianzi, aka lying in your face being more polite than bringing bad news, classic chinese
Same with cheap chinese scales. They're good value for the price, but absolutely not in the professional instruments league. I can't imagine that someone would seriously suggest this as equipment in real lab :-)
Quick are the choice of Polish professional repair businesses for years now.
Quick seems to be well distributed in Poland. I had to buy mine from there to France for around 250€. There was other offers in Europe but not for the beefier 861DW variant.
@@nombinator bst 868 its better than quick 861dw
400C at full airflow seems a bit excessive but I can't fault the speed, especially for the big FETs. I've used whatever hot air station Sparkfun sells before but this one definitely seems worth the added cost.
I have the sparkfun station & use it for repairs. Gets you there, cost me 200 plus COD charges in Canada.
I bought an 858D. But I bought it only for heat shrink tubing. I’ve got some good guns, but for smaller wires and such, they’re too big and overkill. Never tried it on surface mount components. It does come with several sizes of nozzles. The temp setback does work. Also, I got it on eBay for a bit over $40, shipped. Seriously, for $40, it’s pretty good. This model is available from a number of different vendors with the same, or similar look, with different names.
When you turn the holder around, you can pull the nozzle and have it cached in the cup. What for not having hot metal things rolling all over your bench. ;)
I think if you put a scope on the heater you would see it switches fairly slowly, that causes the lights flickering... just the branch circuit voltage drop due to the heater load. I get lights flickering with a temp controlled heat gun when the lights are on the same breaker. Louis probably has the same thing, needs isolated circuits for lighting vs high power equipment. But, as a renter, doing electrical upgrades is just donating $$$ to the landperson...
This right here. I have a different SMC rework station and when it switches the heater on/off it causes heavy voltage drop on the bench circuit, sometimes fast enough to get a nice flicker going on the bench lights. It is far worse on a 110v system with that 1kW load.
micksam7 Bingo. It’s brutal on a normal 110v circuit with any other load on it. It does proper zero-voltage AC chopping (watch Louis’s teardown; they get the scope on it. It switches just like the Hakko or any other high end unit, it’s just much higher current) and basically everything else right, but there’s only so much it can do with weak sauce US mains circuits.
That "Quick" unit is very nice. A while back I picked up an 898D unit which I like very much, I stole it for $45.00 shipped.
Probably someone already commented on this, but it seems there are two models, the 861DW and the 861DE. The DW only goes to 120 l/min and the DE is the one that goes up to 200 l/min. So the display is actually indicating the air flow in l/min.
Louis Rossman is the man! 😍
no he is the Ross-man! :D Im gonna jump of a bridge now...
AcolyteArathok you deserve one internet
uuuh dont know if i want that xD with all the offended people and stuff around xD But thank you anyway! :)
@ruuhkis......"Rossmann"
The motor may look 'wimpy' but you'd be surprised how much power a small brushless motor can deliver. For a robotics project we used a brushed motor of about 15W to drive a dribbler system to move a ball. This motor was replaced by a tiny brushless motor from maxon motors (i believe it was the EC max 30) which was just 30mm x 62mm, a lot smaller than the original 15W brushed one, yet put out an incredible 60W of power.
This is the actual motor used; www.wonsmart.com/English/Product/0586241350.html
It's a torquey little brute, 17,000RPM unloaded speed, 8K full load delivering a max torque of 58 mN-m. Real ball bearings. 3 hall effect sensors, 3 phase. 110-ish watts under full load. Very narrow and light spinning mass for ease of balance and quietness. Excellent choice. Not a cheap motor either,.
True, for quality motors you have to spend big bucks, but its worth it. Next to clearly better performance and being quiet, they last a loooot longer in my experience.
Hi great video. Switching between Celsius and Fahrenheit can be achieved by pressing both the ch2 and ch3 buttons for 3 seconds. (Sound can be toggled on/off by pressing ch1 and ch3 for 3 seconds)
This doesn't work on my 881D
@@mitchcm that's a bummer! I've never used the 881d. I only have the 861d model. (Also I wrote my original comment wrong; it is ch1 and ch2 to toggle sound)
Yay, Dave! Atten consumes 280w and delivers 28l/m. It is standart blower fan, equipped in most of chinese soldering stations.
I have one, I thought for a long time about what to buy, but this was the best choice, I worked everywhere Quick 861DW slow heat accuracy scrap!
Dave and Louis are both awesome. It's nice to see some collaboration between them.
The 861DW is the 120l/min version! The 861DE can do 200l/min and has 1200 W
I also have this Quick Station. There is nothing in this price range that can compare. Hakko and Weller is almost 3 times the price of the quick. I have mine for almost half an year and I'm still very impressed. Unfortunately mine has a "beeping" noisy motor with high frequency sound -.- but beside of that if you searching a hot air station right now. There is no way around the quick
I second this - Quick appears to be a truly high-quality manufacturer. My 861DW, btw, doesn't make any beeping or otherwise annoying noises.
One correction, airflow on the DW model is only 120 (like it says in the display). The DE model of the 861 series is a 200 L version (and 1200 watts instead of 1000 on the DW). And on the DE the LCD setting goes to 200 (as expected).
861DW has 120l/min, Atten I think only has 24l/min.
Neat that Louis sent you this
32:11, not You mistake, just use FLUX easy to remove after desolder process and vacuum tweezers to lift big BFA chips. Good to use termo sensor and best way to use preheater set to 100-150 st C. No to fast heat or internal silicon can crack.
Louis's mains just can't handle heater consuming that much, it is not EMI. He needs better wiring.
Alex Taradov He leases. Any improvements he loses when he goes.
Yes, I know. And he is going to be kicked out of the place at the end of the lease. All I'm saying is don't overthink it, the reason is simple.
Is Louis in 220/230 V mains or that ugly 110 V US custom mains voltage ? That could be part of the answer.
@@nombinator lol not sure how the nation that invented the grid has an odd custom voltage relative to later adopters. As for less subjective I seem to recall 50hz is a bitch for motors. Having watched enough LR I'd guess he chose to use recycled soda cans instead of copper wire 😂 220 easier to get a lethal hit from too no? Simple i=e/r
@@johnw1385 240v means lower current for the same power, less voltage drop for a given conductor size or cheaper conductors for a given voltage drop. Fatalities in modern GFCI protected installations are very rare.
I've had mine for several months now and it's great!
I'd guess the flickering lights is from the heating element. When it's cold from being off or cooled down from being in the rest, it's going to surge the element at full power to bring the heat up as quick as possible, then likely PWM the power to the element to maintain heat. I see the same with my cheapo heat gun like the one you have. My entire bench is on an APC 1500va SmartUPS. When the heat gun 1st comes in it nearly maxes out the load the UPS can take for a few seconds, then it levels out to a much lower power draw depending on the temperature set
i just bought the Atten 858D+ for 27 euro.... price-performance unbeatable. for hobby stuff its great;)
wait what the heck
I usually give the reworked part a slight poke with tweezers to make sure that it reflowed, then I lift the part.
A really nice hack would be getting cold air if you press temp up and down at the same time
QUICK 861DW professional mobile phone repair and repair station, using brushless vortex fan, adjustable air volume, wide range, can be used for a variety of purposes.
The system has the function of automatic cooling of air volume, which prolongs the life of heating elements and protects the hot air handle.
I always use the stand the other way round. That way the nozzles don't fly away but fall in the tray instead.
Dave, shouldn't that stand be used the other way around? Both for the attachment removal (so the attachment falls into the cup below) and for the weight of the cable pulling the hot air iron into the stand instead of pulling it off of it like in the video at 4:50. 🧐
Hall Effect type thing. I inherited mine without the stand so was unaware they auto switch off when in a stand. Drove me nuts while trying to replace the voice coil on a big woofer. Damn thing kept turning off when ever I brought it near the speaker. Had me stumped for awhile.
It's great to see collaborative youtubing. Well done sir Dave!
I bought a Quick 861DA about 8 weeks before Louis got his... i'd been deliberating on it for weeks. Glad I made the right choice. Wholly justified by your review too Dave. Odd thing is I get the same light flicker as Louis.. keep up the good work :)
Dave Approves !
That's why I bought one myself.
Questions, would the fact that it is higher temp inside of the Nozzle have anything todo with the loss of heat as the air travels to the component? I am looking at get a rework station. Never used one.
Compare Quick 861DW with Best BST-863, and with NT 762E, low price product to one category.
Quick 861 DW and Best BST863, inside the same, the parameters are the same, but the price is lower twice at BST 863. Do a comparative review.
When I read the title I thought "Quick" was referring to the review itself, and I was thinking "37 minutes isn't a quick review..."
Thought the same. "classic Dave, puts the word "quick" in a 30+min video" :D
As for hacking it, I have replaced the firmware of a solder station with proper PID control as well as zero cross switchin on the triac. Also display of the real temperature vs. the set. Note that afaik the atten shows the real temperature only when it is in power down mode, when it thinks its up to temperature it never shows any overshoot, but when you then put it down, it suddenly does.
Regarding the loctite on the ground screw, I have seen some where this caused it to have no contact as it crawled in between.
The quick uses a remarkably well-tuned PID for temperature control. Dave's experimental methodology (sort of vaguely stuffing a thermocouple bead into the nozzle) is, well, poor. I set up a proper jig to hold the handpiece with the thermocouple in free air 5mm from the nozzle outlet so I could test/offset it properly shortly after I got it, and aside from the time taken to bring the nozzle up to temperature, the output is astonishingly accurate. Within ~5 degrees for the whole range, getting more accurate as the temperatures got hotter (up to the limit of my thermocouple anyway)
So when he says 'it must be lying about temperature, it can't be that stable' I believe he is mistaken.
Have you posted the Firmware?
All reviews said cheap blower not so good and only for ocasional work, but thats what i needed so i bought it for 50 dolars. Impressive, especially for the price. Now your review is first where i see how capable cheap one is. True its slower, but with so much headroom on the temp i dont bother i will be needing more expensive any time if ever.
And one if best parts with my cheap station is it stacks perfectly with my other tools!
9:43 Isnt that sleeving around the wires for heat protection?
Can you see this thing overshoot glowing red hot at about 26:13 in the reflection of the pcb? That would be at least 650°C
It's just like most tools and equipment, the more you use something, the more you can warrant spending on it. I think the cheapi would be adequate for most hobbyists but obviously the one that's 4 times the price is going to be better
I came here to see the 858d in action because I just bought one and wanted to know how it would stack up against a professional machine. Thanks for the video. It really helped and I think I can do my amateur stuff with the 858d just fine. I just need to be a bit more patient. Great stuff!
Not even watched it yet, but thank you Louis been waiting for this since he mentioned he sent you one. I have been trying to get a filter right to kill the feedback that messes with the lights since I got mine.
I got mine QUICK 861DW a few days ago. For my unpleasant surprise, the airflow controll on this brand new unit seemed to be stuck on max. level. If I went below 112, the fan just stopped and a few beeps later it showed "ERR" message on the display. Upon closer inspection of the motor driver board, I noticed that the R59 timing resistor is simply missing. Since my attempts to measure the value of the C53 were unsuccesfull, I just assumed it to be 10nF. According the MC33035DW datasheet, fig.1, with 10nF cap @ 25khz, the timing resistor should be around 4,7k. so I teporarily soldered one in between pins 8 and 10, and voila...no more error messages and the airflow controll appears to be working just fine too. But just in case, could someone please look at the original value of the R59 on the motor drive board and post it here?? thanks very much...
The Atten cost me around $39 American. Same experience, but Atten is adequate, and it's good for for heat shrink, and heat polishing acrylic for DIY light pipes.
Louis will not know different settings he just put heat to max and regulates with distance. :)
tuxontour :-D
:)
at 26:00 - you would've been less than 27 seconds as shown at 27:00 because you weren't heating up the rear pad... the solder on the side did become liquid, and then you focused on the front instead of more in the rear. It probably would've done better if you hung around the large pad more because when you started getting area hitting it from that side it came right off.
13:28 the cable's copper seems to move inside the crimp. If those are not made correctly, can became quite loose.
At 26:36 you can see the solder under the other D-PAK chip flowing, but not the one with the heat right on top of it.. Weird.
Just FYI, this thing is about 150 euro shipped from AliExpress. This is without a sale going on so you could shave off another 10-20 euro.
Hello, you seem very knowledgeable of this product. I have this station as well and it's no longer heating properly. I replaced the heating element, and it did not fix it. It's barley heating at all. What is the most likely part that's causing it to not regulate the temp?
Here's my thinking.... You set the minimum temperature needed for the desolder and then adjust the power/speed with airflow, since the the heating power carried by the airstream is depended on temperature and airflow on equal proportion.
Radiated switching will also be highly unlikely as the unit uses MOC3041 to drive the Triacs and that is a ZVC Opto Coupler for the heater. Having watched Louis' video, The Hakko also created flickering so I would have a serious look at the mains wiring. High loads on his mains seems to cause the issue. Just my 2c worth.
I'm not sure if I'm a fan of the CH1, CH2 and CH3 buttons, I'd prefer maybe a left/right or up/down cycle button to switch between presets stored in flash. That way you could have many more presets.
You can now get an 858d for 35$
Ditto. Works pretty well for hobbiest level. Been a great addition to my workbench.
Chryseus Do you happen to have a link to the CFW? Thanks!
Louis is a legend
I was using a heat gun in my server room to test some temperature alarm points and noticed the lights flickering too, I think it's because these type of devices just modulate on/off instead of just adjusting the voltage to the element.
If I understand correctly the 1meg ohm resistor from line to ground, supposedly for noise is something which was done to audio equipment in the 1960s-1970s. It creates a live chassis situation. I'd snip that out.
You have misunderstood the video. This is a high value inline resistor used to safely ground the earth strap socket at the back of the chassis. It isn't connected to the live supply in any way.
When it gets hot those nozzles have a tendency to fall out
I ended up drilling a small hole in the collar and tapping it to put a small screw to retain the nozzle
Angled nozzles are handy if you’re trying to use a heat gun under magnifying equipment.
Not a fan of the comparisons with a much larger nozzle on the lower powered station, kinda unfair... but hey
Yeah and he is moving the Atten ways more, he moves it all around the place while he keeps the Quick steady on the places needs to be heated up, that made all the difference: different nozzles and moving ways too much. I for my own expirience can say I like this Atten/Ayouye etc. around 10 bucks airgun ways more than all the ones with the blower inside the housing, I just hate those fat heavy tubes, the cheapos are ways more handy and for me they worked on changing smartphone parts ways better. Also Louis Rossmann is not god and free from failures, he is an image addict, all depends from the price, money has the most value for him, this is exactly what he is telling all the time, if you put a pile of shit on his table with a high price sticked into it, he also will say it's gold. Anyway, compared to the Atten, which costs up from 30€, the Quick is ways too expensive, just look inside it and you can count the prices for the single parts, I just can't get over 100€ for the parts plus the handpiece, stand and work its maximum 180€.
I’m not a fan of those hand pieces with the noisy blower in them. I prefer the blower pump inside the unit like the Aoyue which means the hand piece can be a bit smaller. But I agree the comparison to the Atten using a larger nozzle was unfair.
Mhh ok, thats what all say, but I think a little more noise is more tolerable than the heavy hoses, but ok.
it's not meant to be fair... it's meant to show you the difference between a "good enough for 9/10 people" and "professional grade" so you can see whether its worth spending the extra money.
30% more power for 5 times the price, ...what happened to economies of scale? (Same goes for solder stations. Double the heat transfer for just 6 times the price?)
This isn't like optimizing power to weight ratio of an engine, This is basically just a simple doubling [size or count] of the main power regulators the controls basically remain the same.
Nice fair review Dave. Stand was being used backwards, recessed bin area will catch tip when removed hot.
Type-K thermocouple can go from -270 °C to +1260 °C (www.thermocoupleinfo.com/type-k-thermocouple.htm), but it's just the metal wires, not the plastic insulation. So, at higher temperatures you can get the end of the insulation slightly burned, but the thermocouple will be OK and accurate.
I think the flickering lights is the heating element cycling. No Zero crossing switch.
@3:25 - thats a shot from Louis towards Jessa from ipadrehab (who ordered these 45° nozzles first but Louis got them b4 her)
honestly that temp memory feature on the quick is useful. I have an older cheaper model and switching between desoldering temps and lower temps for just melting stuff or shrink is a pain, many of times have I grabbed mine without thinking just to hit some heat shrink and its set at 400C
people also like the
Quick 957DW+ for $113, only 580W and 100LPM air, some issues with transformer coming loose (vertically mounted-Doh!) but good if all together
Still way off my budget. I'll stick with my hair dryer I guess.
Justin Spencer Save your nickels. This will save you a huge amount of headaches.
Didn't used to be. Louis endorsed it and the price goes up. Soon it'll go for the same as a Hakko station.
But, when you're buying tools, it's good to pay more and research thoroughly.
I got the Quick 857DW, so far it's been great.
This one's a forum classic, many many people have been recommending it for a long time.
for quick control the Atten dial knobs win made up for i guess with the 3 presets
Just use any old heat-bed (kettle, whatever) and you will do everything with cheap hotair/soldering station. Temp. driver is a must, with some stm8 at least, ntc and relay, still cheap and effective. The other way is to preheat. Remember, both tools aren't complicated, at least chinese fan-fun won't blow your elements as you might expect from quick set too high with its flow.
At one-fourth the price, the Atten looks perfectly adequate for most home users. I would expect that a slightly smaller nozzle would concentrate the heat probably increase performance slightly.
Actually, gas soldering irons with the hot air tip can do the same especially good when repairing something in situ. A good example of this is the iroda solder pro with hot air attachment
It's funny watching dave do a similar job to Louis, but without adding 6 gallons of flux to the board before desoldering :)
I've used Aoyue 968 for the last 11 years. Had to replace the soldering iron part of the station, but as for that, it's been a trooper. My only complaint is there is some radio noise around 150Mhz and again at 155Mhz that interferes with my testing of radios. I usually have to program the radios to something else so it doesn't get interference.
Easy way to semi-bypass the RCD, (though is potentially dangerous in the wrong hands) disconnect the appliance earth and connect it to the neutral. (its still earthed via MEN) make sure you 100% check phase/neutral polarity. Any potential leakage to "real" earth will still trip the RCD, but current in the earth wire wont. handy for PAT testing on construction sites.
This sounds suicidal at best. In many (most) countries, there is no difference between live / neutral in mains wiring, it's just a convention with no practical importance. It's literally a 50/50 chance you'd be connecting earth to live.
Someone please explain how the same tempeature and max airflo rate can produce such dramatically different results.
The math/physics suggests a variable that is beyond the machines; for the machines are delivering the same product = hot air :same temp :same max airflow rate... 3+4=7. What are the variables here that can account for almost 2x the time needed to get the solder to flow?
The flicker is a LOW FREQUENCY behavior. An EMI filter does not even start having any effect on it. I have had my battles with brush type DC motors commutation noise and the best EMI filters were only marginally effective, so I studied the things a bit. The first thing to realize is that all the filter characterization is done at 50 ohm in and 50 ohm out impedance. So, “your mileage is likely to vary”. Then the best filter I ever measured started its attenuation at 8 kHz. The commutation noise base frequency varies with the speed from nearly zero to some kilohertz. Only the harmonics get attenuated.
A brushless drive produces its own corresponding commutation. The difference though is a lack of real sparks and thereby less harmonic and especially non-harmonic noise.
As already stated, the low frequency variations causing light flicker is a different story. When the load current varies well below 50 or 60 Hz line frequency, you get voltage variation imposed to the power line due to the wiring size and length (resistance) and probably even more by the feeding transformer impedance (mostly inductance). As the movie industry found early on, the subjective flicker is really bad below about 25 Hz. So, they “cheated” by opening the projector shutter 3 times on each movie frame.
Because SCR and Triac drives caused harmonic noise, some people designed mainly for temperature control systems that turned the heating on and off for half or full line cycles. And you can guess what happened: Huge flicker complaints, of course.
I had to laugh at the "LEAD FREE" stencil.
I just picked this up as a side fun project to learn. I can't seem to desolder smd leds for some reason. Either I'm not getting it hot enough or I am afraid of torching stuff..lol this is my first time and I have mulitple PCB's that are dead and just practice on. I can't seem to get the hang of it yet. I know how to solder normally but totally new to hot air rework stations.
My issue with the 858d is the handle. I have safety concerns regarding it.
