It's like watching a coked up engineering version of Bob Ross' "The Joy of Painting." I love it!
+Nicholas DeLessio I'm laughing so hard TY! I'm twitching now myself!!! The joy of painting with crack........:)
That explains why EEVblog give me ASMR sensations.
It is very very inspiring indeed, really brings across how much fun in fact there really is in doing electronics :-)

"Now let's just add in a happy little solder joint... There"
In a pinch, if you need a small diameter solder but you only have the larger diameter solder, a trick I personally discovered is to simply pull and stretch a length of the solder, making it a smaller diameter; the rosin core stretches with it too -- it really works quite well!
Wow! You have a real life wire stretcher!
I thought I was the only one who did this! lol
@@mikestribling7574 Great! You're the only other person I know of who also said they discovered that trick!😃
You know, I was watching the first Matrix movie today, thinking that would be so awesome if you could just instantly download the ability to do anything into your head with their technology. Then I realized, TH-cam is pretty close to just that.
@@mondo_burrito Lol. I don't remember this video or leaving this comment so I'd say chances are high.
What I really appreciate about the 3 soldering tutorials is the reinforcement it has provided the methods I have been using. Been soldering electronics for about 30-ish years, and it is nice to know I am not the only one who feels soldering results are a testament to quality, care and workmanship.
Long time viewer, think I joined on EEVBlog #8...I think you've done and continue to do a massive service for the community and I'm happy to buy you a sandwich to keep you going.
Don't even listen to these negative people. You've covered absolutely everything that was necessary. All your warnings and comments were necessary. Thanks for spending time and sharing with us.
Thank you for your time in giving us all your version of How To Soldering Parts 1,2 & 3.Have a nice day.
Just wanted to say thank you. This video is how I learned to do SMD soldering and has opened up a whole new world for my modular synth. I really appreciate it.
Dave, just wanted to say: your tutorial on how to do SMT work helped me to put together a board of my own design recently. Thanks for doing this video! Super helpful!
I think it's great the way the presenter is perpetually surprised, joking aside awesome enthusiasm, nice to see.
Just went, desoldered and resoldered my LCD display after watching your videos, with amazing results. Thanks a lot!
Took a Pace certified surface mount class in college and some of the solder connections would not meet the certification requirement. His technique is spot on. Recommend cleaning pads and adding flux earlier in the process, last I checked flux isn't that expensive. Excellent drag attempt, try using a smaller tip.. Decent solder paste example. 1st 2 pins looked lacking but was corrected prior to adding heat. ADD FLUX, ADD FLUX, ADD FLUX.
Dave: Thankyou for posting this vid - I it's an old one now but I find myself rewatching this every few months or so, when I've let those fine-tuned skills atrophy and I need a refresher :)
Thanks for sharing the tricks to make this stuff! :)
Thanks for making this approachable. Very glad you showed both how to do i right and what can go wrong. Having a something to compare on your own is invaluable!
Thank you so much for those soldering tutorials... I'm a beginner in electronics, and after several attemps over the years I always sucked bad at soldering. Now, 5 minutes ago, I finished soldering 14 wires on an SMD chip (destroying 3 other chips in the process but still), which I never thought would be possible for my clumsy self. All thanks to you! Cheers from Canada!
Dave- thanks for publishing this. It was really informative, and to be honest until I watched your video I didn’t realize this sort of thing was possible at home. It’s really opened up doors to me, and thanks to your efforts it helped inspire me to build my Lidar project that I’ve just put up on my own channel and have been talking about on your forum. Thanks again, and much appreciated!
Dave, THANK YOU … SO MUCH for your tireless and very well prepared video. You show a great deal of enthusiasm and encouragement for the newbies. I sincerely appreciate your fun, honest, thorough and encouraging tone in these videos. Absolutely wonderful series and in general, your videos are GREAT and really show how much you care about your audience and the passion shows. THANK YOU! I learned a great deal.
I must have watched these 10 times ova now ,such a great set of tutorials .Thank you !!!
Easily the best videos on hand soldering for beginners, I have ever seen.
Brilliant.
Excellent video! I recently needed to assemble some prototype PCBs (high power LED drivers) - my components included some 0805s, some SOT23s and a few SOD323s. I spoke to a professional friend who gave me some general good advice (he described "tack and re-flow" and gave me some lead-free thin solder). Then I found Dave's video which actually showed me how. It was enough to give me the confidence and technique to do it...and all three boards worked first time. Thanks Dave & EEVblog!
Hey man.. thanks for this video.. I had the opportunity to move from a job conformal coating PCBSs to a career in electronics repair and technician work. my one weakness was SMT work. being a hobbiest (instead of a tertiary qualified graduate) I'd only really ever worked through hole.. Thanks to the quick guides you made I now have a much better position.. Thank you Sir. I do hope to buy you a beer some day :)
I about to have to reflow a a 32pin ZIF flat cable connector. I think this video has given me the courage to give it a try. Saving a $650 DJI Isnpire 1 transmitter with a $2 part sounds like a plan :)
all dave's smd tutorials really helped me with my boards.
Thumbs up for rescuing this video Dave :) I am perfectly comfortable with soldering, but I still enjoyed every minute of this video. Thanks!
I fucking love every bloody video this lad has out. People flak all over and mull about
Oh his voice is too high. blah blah you're not explaining everything blah blah
I for one have learned so god damn much about my trade just by following his direction and knowledge
Cheers
+Johnny Codemunch
I'm such an electronics noob myself, and have very little knowledge of components, soldering, schematics and DC designs; yet for the past 2 weeks of viewing almost every single video on Dave's channel, it's inspired me to spend over £600 (GBP) on a mini electronics lab so far, and I'm still buying stuff for it.
You can learn so much from this channel. The advice is fantastic, the content is informative, the guides are understandable, the knowledge gained is insane. Even for a newcomer. You can start from nothing and end up with such a vast array of electronics design/engineering knowledge from just viewing Dave's videos and the EEV Blog forum. Finally starting a project on creating a homemade DC power supply, thanks to this channel
+Kyle247l
I too have just restarted playing with electronics again at
the age of 71. The problem is I keep buying bits, then view his videos, only to
learn that what I have bought is utter, utter garbage.
Cliff Woolston
aha. Same here. Terrible solder, terrible flux, terrible desoldering braid, and a plug-in iron, while using an actual heat gun as a rework tool, but I'm only 20 years old right now, and I made these mistakes at 15 years old. We all learn from our mistakes though!
+Cliff Woolston At least if it's utter garbage you don't have to be careful when using it.
я тоже охуел! fuck
Try tinning all the pads before you solder a big chip, then just press each pin into the solder with a dry iron. The results are as good as reflow, I've done thousands now!
Great series!
Thanks to your soldering tutorials I can now properly solder stuff. I've been using a soldering iron since I was a little boy but nobody taught me the right technique. And thanks to now being able to solder the right way I could repair my bricked Asus eee PC netbook which overheated during BIOS update. I could desolder the SO-8 flash chip, rewrite it with the help of a Raspberry Pi and solder it back in without damaging the chip or mainboard. All thanks to your excellent videos Dave! ;)
Thank you, Dave! I have been following your channel for years but have never left a comment.
I learned to solder at 10 (I repaired my NES clone), but my soldering always sucked. Most of the time I didn't like the end results. Watching your soldering tutorial was like a final blow for me: something clicked in my had. After watching the last part of the tutorial I took a cheap Chinese Arduino Nano clone which came with unsoldered pins and tried to solder them in following your advices. The end result is beautiful: it looks as if the pins were soldered by the manufacturer.
Am I so grateful that I cannot describe it!
Blessings from Ukraine!
I love you, Dave: "Stevie Wonder could solder this thing" :D
Great tutorial, thanks Dave.
A classic video. Exactly how I got my start: by watching the best on the Internet! Thank you for continuing to make great videos!
All three video's are fantastic! Basically learn to solder in 90 mins.Aomething that always intimadated me. Now I have all the confidence I need to do a project of any kind. Great job Dave and thank you!
Thanks for the tutorial. I feel really confident about doing this now. Thanks again.
J
Best soldering tutorial ever. Thanks.
Thanks for this series of videos! - It's been a few years since I last soldered anything and wanted to actually get my technique right rather than just trying every method until it works.
once again you've taught me truck loads. thanks a lot. im going to get myself a chisel iron and flux. your videos are awesome.
You are the Bob Ross of soldering, and I mean that in the best possible way! I was intimidated by my first through-hole kit, which went swimmingly after watching the first two vids. Now I've received another very simple kit, but with a few SMT resistors, and I was intimidated again. Not any more after watching your vid. Thanks!
very nice and easy too understand Dave. Enjoyed the video and subbed.
Wow! I just watched your video and did my first SMT ever: SOT23. Thank you so much for the demo. Best 15 minutes ever!
This is an awesome video. It has prepared me for an FM transmitter project. Now I feel more confident about soldering the components to the board. Thank you.
"Stevie Wonder could solder these" hahahahahahahaaaa.... 1st joke i have ever heard in a tech vid.. wade a be Davie.
+Greg D I was thinking that I could land a helicopter on those pads. I'm used to doing ultra-fine pitch stuff you need to do under a microscope.
+Andrew the Celt do you hold the iron with your hand or like a robot and joy stick?
nicholas feltman by hand. With practice you can do components with 10mil leads
But can Michael Fox solder that? That's the question.
@@andrewthecelt3794 would you say 0805 is doable if one has never smd soldered before? (seeing the size of these things i'm kinda worried i wont be able to make ut without practicing a ton first?)
Ahhh, David-san! Flux on and Flux off!
Thank you Dave. I'm glad TH-cam worked out this time with the upload.
I love you Man! Your enthousiasm is contagious and inspiring. You've taught me so much already these past weeks, watching several of your tutorials a day. You're my favourite teacher at the moment, can't get enough of your stuff :-D
more of these tutorials please :)
17:08 did you just kiss your wife? xD
LOL
LOL... well spotted (or.. Heard)
Kissed his wife, are you crazy?
He kissed the soldering station, of course!
@@JC-wh7jj nope . Kissed the soldering iron tip. Way hotter than the wife 😅 😂
Great tutorial, I'm not really new to soldering, but never done such precise SMD soldering. Going to solder a new BIOS chip to revive an old laptop of mine. Lets see how it turns out! Can't wait!
Really awesome video dude. Learned lots of new things. Liquid flux, dragging method, more info about hot air and solder paste. That tip that holds the solder... never heard of that and been in electronics for 36 years. You have a very nice way of explaining the subject.
Stevie Wonder could solder this thing!
Incredible voice
It is infective. I got british from that. Took me several minutes to cure that off.
+Len P ..he's Australian
Jordan Johnson, I know. And you are one of these independence guys?
like "linus tech tips"... after somes mintues i must stop the video ah ah
This is the first of Dave's videos that I saw. Found it when researching hand SMD soldering. Great video, thanks Dave! You're right: it is a piece of cake! I've done 0402 components and even some QFN packages (with hot air) and it's great fun! :)
Based on your video, I bought a well tip for surface mount soldering - works great! It makes drag soldering so much easier. Thanks for the great videos.
You are a very nice teacher. I like your vedios. :)
it is "videos", v - i - d - e - o - s.
Yeah, that was two years ago. Now I spell correctly. :D
how much heat does components like that withstand?
+Kentrt lots most are a minimum of 800f
The peak temp in our oven is set at 245 ºC most components are rated at 260 nowadays. That's lead free process. Offcourse when soldering by hand there's a thing called temperature shock but that never appears to be a problem. The most sensitive are the electrolites which are sometimes rated at 240 something then you need a special oven program to solder them. Sometimes we use 'hats' made of kapton tape to shield the elco's a bit. Some time ago there was an order containing those really old philips rectangular flat lying electrolites at the lead free temp those things popped like popcorn.
And sometimes some electrolites are soldered by hand afterwards but it's getting more rare thankfully.
I love how Dave materializes in.
Hi Dave thank you for the last 3 Soldering Tutorial's I really thought it would be impossible to solder surface mount components. Thanks for all the tips Dave. Kind regards Steve.
+EEVBlog,
When you say 350, do you mean 350 C?
Morahman7vnNo2 Thanks!
Does that extra flux from the flux pen need to be removed when you're finished soldering?
Some types need to be cleaned up after soldering, but most of them evaporates perfectly leaving no appreciable rosin layer. They are called no-clean types.
Péter Kiss
thanks for that tip! I'm new to this and the idea of cleaning flux off a pcb with water and an esd brush really scares me
You should do that with pure alcohol (denaturated ethil) instead of water.
aha! thanks again Péter Kiss
neppy5 It depends. Usually not but if you need to conformal your pcb then you will need to remove the flux residue. No clean fluxes still leave a residue that can be cleaned off for a better conformal coating. Most hobby boards will not need conformal coating.
lol You make it look so easy. I’m okay at it now, but the first couple times... yeah. Life advice worth considering. If a new task is frustrating you, put it all down for a bit and step back for a few.
Great video.
He has pretty much every tip you can conceive. He likes the one he is using.
SMD soldering is really a bear when you have a hangover :)
For surface mount soldering, the secret to success is not thin solder, as most amateurs think, but using very liberal amounts of flux. Applying flux first and touching the pad/component with a tinned tip (which needn't be fine at all really) gives you perfect solder joints fast. Big fan of these videos but there's always room for improvement. :)
EEVblog Hi Dave, I am enjoying this video series on soldering very much. My dad taught me to solder by giving me old electronics and an old Weller RED iron to struggle with, and would let me sit there till I had stripped that board clean , shows him and re-assembled it as it was. Man, that was a steep learning curve.
My Reward - MY choice of project from DiCK HeadSmith's Funway 2 book and the book it'self. And I bult them all.
The Shortwave Radio was the most interesting one I found in that book, the most complicated, etc. but it had infinite treakability.
You should do this one as a video, or even a Jaycar kit vid just to show that it can be done.
Dick Smith Funway kits REALLY opened up the scene to people back in that era, from young kids right through to adults.
Started to dabble with the Jaycar kits later on down the track but when everything became PIC this and PIC that, I began to lose interest since you could no longer build something without programming it first.
You have me reminiscing of my training for my (now expired) soldering cert. We used that exact drag method when we had to solder the our 100 pin QFP IC. I don't know what the pitch was, but it was a tight pitch. We were running at almost 400 Celsius.
use decaff
psoriasisman I don't drink coffee.
psoriasisman Don't be an ass. This is a good video, and the accent is cool.

psoriasisman cause then you´ll get psoriasis.
tnpsegim dont drink soda
good Tutorial :))
Very nice video! I started out with applying solder on pads and tack as shown in the video. Doing some (400+) 40 pin + IC's, I've learned to apply a tinning layer of solder on one leg, not the pad, then its easy to place the IC absolutely centered. Then Touch the iron to the tinned leg centered holding it in place and finally fully soldered in about 20 seconds, looking like a machine did it. Maybe one day I'll make a video showing this described and other tips I've learned on the job.
I love your soldering tutorial series. Very informative and well done!!
awesome
now desolder it
Did you know? if you dont align the components on the pad and the value written on them with the markings on the board, the electrons wont flow properly
Basileus s
I thought I was the only one that realized this, glad somebody else did as well.
The camera was in his way, no doubt.
@EEVblog - great stuff Dave, really love your practical tutorials and teardowns - Thumbs up from me!
I like his detailed illustrations and explanation.
Good video but please don´t be offended, The tip used to solder SMD items in this video is TOO BIG!!!, with a small solder tip you can get a better solder quality!!!
I would disagree. The chisel tip is right for the soic8 as it heats both the leg and the pad simultaneously. The 'well' (or wave) tip is perfect for the fine pitch IC. I think you may also be being tricked by the magnification.
Ian Montgomery The tip used to solder a pic24fj256ga106-i/pt 64 pin (each pin has 0.22 mm )must be as shown in the link lines below 1/64" conical tip to avoid jointed leads on the SMD PIC:
paceworldwide.com/products/tips-and-nozzles/soldering-iron-tips/ps90-tips/ps90-soldering-tips/164-in-conical-tip-357.
Mi comment is due to I saw when you´re are soldering the PIC and 2 leads are jointed with solder (min 20:20)
Regards!!!
eduarsan1
We use wave/well tips (these have a 4.5mm well) for QFP hand soldering (we usually use a placement machine except for protos) or alternatively we will use hot air.
If you have a lot of flux over the leads you wish to solder then the job becomes easier.
Stevie Wonder could sew on this thing xD
You're an awesome teacher! I enjoyed all your soldering videos and they will greatly help a noobie like myself. I love your energy in this vids! Thanks!!
So cute watching vids by Baby Dave. Audio has come a long way since these early vids. Keep on keeping on Mr EEVblog
You almost sing/rap when you talk.
This is no reflow soldring! For reflow soldering you need a soldering paste and a reflow oven. When you heat up parts like in this video, most of them are damaged after your soldering.
*****
I agree with you. Reflow should lessen the prospect of heat damage to components too.
Ian Montgomery
This is defenetly not a resoldering process. The reflow soldering is a defined process where you use a soldering paste and an ofen to solder the components to their soldering pads. When you use a soldering iron it's not a reflow soldering, even if the soldering tin is liquid again. Use google if you don't trust me. You will not find any description with a soldering iron and soldering tin (manual solder) using the word "reflow".
The reflow process uses low temperatures to protect the components from getting to hot.
***** I guess part of the reason is that the ovens used for SMD lines are called reflow ovens so people associate reflow only with SMD.
Martin B. Our reflow oven hits 250C for a very short time.
Yes, might be. Some components (or materials) need higher temperatures than others.
I do enjoy your enthusiasm in all your video's!!
Great stuff as usual Dave. On the D packs I prefer to apply solder to the ground plane and reflow the component onto the board and then do the legs.
Regards
Trevor
I'm sure you're aware of how Stevie Wonder lost his eyesight. He was an up and coming soldering apprentice in his dear fathers's soldering factory when one morning, as young Stevie, as they called him, was working away soldering a resistor. He had filled the well of his soldering iron with solder when, suddenly, a co-worker who possibly had too much coffee that morning, bumped into young Stevie. Solder heated to more than 1200°c splashed into his eyes leaving him not only blind, but also unable to practice his first love of hand-soldering. So try to be more sensitive about blind people's abilities. Luckily Stevie Wonder had this whole music thing to fall back on, but that shit musta hurt lika a mofo!
Wrong lol
This guy has almost 2 hours of this in 3 parts. If he wouldn't jabber so much he could cover all this info in about 20 minutes.
Thank you very much for this tutorial. You have no idea how immensely you have helped me! Fantastic job!
Nice tutorial Dave, I still do tack and solder on TQFP100 0.5mm spaced parts. Works well with the right tools.
my god!!!!! this guy talk sooooooooooooooooooo much
This is an "Crazy Aussie Bloke" and so he "has to talk much and crazy" :D It's his habit and "trademark" of these videos :) If you don't like it, there are tons of "serious" and "sad" video tutorials out there ;)
Once I saw the first EEV video I also thought "what the...." but then it became funny :D Especially the parts where he breaks something accidently or turn something apart.
TheThore
Yes I agree with You, but i still watched the videos, D is very savy and yes also very funny.
the point is, sometimes he talkes too much about obvious stuff that really yields to boring.
I also appreciate signalpath blog, mjlorton and my best fav. w2aew.
thanx.
Yes sometimes I fast forward a part, too :D But the "Bloke" is funny and educational. I may check the others out you mentioned. Thank you.
MY GOD!! Your comments are sooooooooo meaningless..
tnpsegim if you were an EE you probably would understand what my comments meant.
Great stuff. First video showing easy ways to do this for us normal folks. Thank you!
I'm doing my masters in engineering a UniMelb. I love your videos and your passion for electronics. I would be glad if you could show some BGA soldering.
Thanks and keep on doing the good work.
Thank you for your time in giving us all your version of How To Soldering Parts 1,2 & 3. very use full tips give this area....
Nice videos Dave (all of them not just the ones on soldering techniques) very informative and instructive keep 'em coming mate.
Thanks, that was exactly what I was looking for for a while now! Noone in my part of the institute can do those well!
Just buzzed through this series. Thanks for the awesome information.
Awesome tutorial, very informative. It makes me want to break out a soldering iron and solder random parts to a board!
Thank you so much for these, I've realised why all my soldering has been crap and I gave up, I always soldered the tip first, had a crap iron an was using cheap crappy solder, I can't wait to give this another go as I love building electronics kits but gave up because of my bad experience, Thank You Again!
Many thanks Dave, just tackled the little bit of SMD I needed to do. Your vid helped enormously and the little buggers don't look too bad! Phew - glad it's done :-)
Thanks for taking the time to do this, really helpful!
It's always easy when you see a professional doing it.
Try using paste solder on SMTs. Basically a mix of flux and solder beads, and you can apply to each pad with a syringe. We used that for SMTs, put the solder down, placed and held the component and then flowed the solder by hand with a micro tip iron.
Learnt heaps from your soldering tutorials so far. Awesome. *thumbs up*
If you do a lot of soldering and de-soldering, you're bound to use a lot of flux, in which case I suggest making your own. It's dirt cheap and really easy, just dissolve a pre-measured amount of rosin, also known as colophonium and pine resin, and dissolve it in a certain amount of denatured alcohol or isopropanol. You can even make flux in different concentrations that way, ranging from 40% (ideal for soaking de-soldering braid in when de-soldering SMT chips) to 85% sticky syrup.
Thanks for producing this video. It's very useful to me for my job. You have made my life easier. Great job!
