Basically, flux makes the solder change perfectly to the shape of the contact, and stick nice. Flux makes solder turn into the T1000 from Terminator 2.
@@Ilegator Yes. The difference is that rosin core solder already contains flux. But you'll have to apply the solder into the joint. Flux cleans the joint surfaces and protects the joint from oxidation, which is what we see when the solder starts looking like crumpled tinfoil, looks cloudy and forms spikes. But the flux diminishes fast when heated, so the joint has to be perfect the first try. For SMD soldering, you *can* apply fresh solder and the flux will make a good joint. But it's easier to apply the solder to the iron, apply flux on the joint itself and dab the iron tip onto the joint and let the flux do its job. By the time you bring the tip to the joint, the flux from the core is already gone, which is why you'll have to apply flux paste.
@A person who never keeps mouth shut When u desolder , do u need to use flux ? I need to fix a balls up i did , i bridged to joints... I never knew about flux at the time
For those that are confused: Flux is to be used in two cases. The first is with surface mount devices as it is exceptionally difficult if not impossible to solder a surface mount device to a board with a wire of solder. It is much easier to coat on some flux paste and then attach a little solder to the end of the iron and tap the flux paste. The second time to use flux paste is if your solder wire doesn't have a good amount of flux already in the core of the wire. Sometimes your solder will get spiky when you've corrected it too much and flux helps shape the solder into a desirable shape after you've fucked up too much. Also, in the case of Surface mount devices, you can buy flux paste that has solder in it. There exists specialized ovens for this type of paste with a very exact and precise heating and cooling curve. You basically apply paste to the pads on your board, put your components down and then throw the board in the oven to melt the solder and your done. This helps cut down on the amount of time it takes to place all of your SMDs (you can use a stencil) and solder them all down as well as lowers how god damn tedious that process can be.
So if I'm soldering components to a PCB and my solder has a rosin core, I don't really need to add any flux unless I mess up the join and need to redo it?
flux is a mix of components that is acid, especially under high temperatures, the reason we use it is for removing oxidation so the solder mix can get a clean contact, if you dont use flux there might be a space between inside your connection becouse of the natural oxidation of metals, that can make the contact unstable and might even slip out, thankfully most solder wires come with some ammount of it, so using extra flux is somewhat not needed but its good pratice on some cases
At 370 degrees, everything sticks fine for me. I only use flux when I desolder. If I have a smd/set component, I use solder paste, like you said. A decent adjustable iron makes all the difference in the world.
I wish I had known this about 20 years ago! I eventually learned the role of flux and why solder did what it does, but it was some hard, frustrating lessons. This explains in a bit over 7 minutes what took me years of on and off experimenting. I'd give up and not touch electronics for months at a time, eventually years at a time, just because I couldn't get good soldering. This is one of the lessons I felt should have been taught to me in school. I even took several college classes in electronics and soldering wasn't even taught. I'm keeping this video handy so I can send it to people who I teach electronics concepts to. It'll be a huge help.
It's crazy ain't it? We had flux in our electronics course, but not a good explanation of what it does and how to use it, clearly demonstrated here in 7 minutes hahhaa
I've been soldering for decades, even so it was not at all clear to me what point was trying to be made through much of the video. To use flux? Sure, but what point is being made from 1:30 - 2:30? To prove flux evaporates? Is the goal just to get a shiny ball that looks wonderful? And I kept wondering, with all that flux being applied, why didn't the solder wick to the end of the wire? The graphics were truly cryptic. What is meant here by solid solder and liquid solder? Is it all flux-core solder, being applied differently? Where solid = applied from wire to heated joint, and liquid = applied first to soldering iron??? Ok, being critical, but with slightly more effort to explain - IN ENGLISH - it could have been done in 30 seconds, as Michael Noble pointed out. ;>)
Solder Type : Solid = Built-in flux inside the lead is not used up yet. Solder Type : Liquid = Because you use heat pre-place the lead as a blob (on solder iron's tip, or place on PCB), the lead had gone through liquid state once. The flux inside had been used and maybe insufficient when you actually join things. At time soldering = At the moment when 2 things you wanna join touch each other. At time soldering, solder : Solid = At the moment when 2 things you wanna join touch each other, you then bring fresh lead into play the last. In this type of soldering, you can use the built-in flux for a while before you need to add more if you are able to make it quick. If you need to adjust things for 2-3 times though, you may need to add more flux.
@@Niyaz916 You probably have a new tip. The first thing you should do with a new tip is put it in the iron, and tightly wrap solder around the tip a few times, put it in the holder, change the heat to high, and plug it in. Wait quite a while. The loops of solder should melt and drip off leaving a nice shiny "seasoned" tip. Then let it cool down (or use it). Always leave that sliver solder residue on your tips. You can wipe off excess blobs with a wet sponge.
As a newbie, THANK YOU SO MUCH!!! I've seen so many soldering tutorials that either say "just use flux" or "there's flux in the solder", but this is the first one I've seen that really shows the effect it has, and this explains many of my frustrations figuring out how to solder.
True, always use flux. But when soldering THT parts, the flux core inside the solder is enough. Always try to get a good joint without unnecessarily using extra flux and prevent unnecessary cleaning.
I don't usually like instructional videos with no talking (just music and text) BUT this video helped me clearly understand one of the soldering mistakes I've been making for nearly 40 years. Excellent! The camera angle on the matrix board was very artistic too.
Flux is your best friend! I highly recommend the gel type flux over the liquid pens. The gel gives you more working time and stays in the area you're trying to reflow (until heated, of course). I regularly solder surface mount ARM microprocessors, and have drowned boards in flux when reflowing a component two or three times over. If you think that you've used too much flux, you'll be fine. Impossible to overdo it in my experience. When your components are soldered, ensure that all that extra flux is washed off with 99% isopropyl alcohol or PCB flux remover. Flux can be slightly conductive, with the possibility of causing fine pitch SMD components to function unreliably. 3 minutes of scrubbing with an ESD brush and isopropyl will remove the majority of the remaining flux residue. Soldering can be both very rewarding and very frustrating. If you feel like you're getting impatient/about to put your head through the wall, set the board aside and come back to it with a clear head.
Man, that explains my failure. I burned an esp32, despite double-checking and washing its joints. probably because the flux underneath the element could not be removed and it ordered the MCU to operate on 1.8V instead of the given 3.3V... Thanks for brightening me up :)
"Set the board aside and come back to it with a clear head" this. So many times ive found my self doing a project and having invested hours of work into it and because of my impatience, id end up ruining it. Once I realized that when I start getting frustated to step away, things came out alot better and ended up being a far superior end product.
To be honest I really didn't know why I needed Flux because I always added more solder when it started to get a cold joint but thank you so much for taking the time to make this video and I really like that thing you put on the side of the video of how much flux is left that was really cool and help me understand it.
The flux inside the wire is always preferable, in my opinion, since it solidifies instead of living a liquid residue. I always add some flux, but as little as I can, only to improve wetting. Anyway, your excellent video proves the point!
When soldering small stuff with 0.3mm solder wire or smaller external flux is almost required though.. I usually use an alcohol solved liquid flux with a bonpen as applicator, it's usually possible to only put flux on the actual parts so that there is little to none residue at all.. There are of course situations where you might want other kinds of flux but for almost all situations I prefer the alcohol based ones. en.bonkote.co.jp/product/peripherals/bonpen.html
Such a great demonstration. What I took away from this is that flux aids the transfer of the solder onto whatever surface its being put onto, it evaporates as it is heated and without it it causes the solder to not adhere properly (you can see that with the small tail of solder that sticks up after removing the iron from 2:03 onward) and a telltale sign of not having enough flux on a solder joint is when it is not reflective or when it doesn't flow to fill the size of the pad/lead.
Flux is magic, even with rosin core solder, I still put just a wee bit on tabs before soldering, it's the difference between mirror like joints and grey blobs. It also keeps it from creeping and bridging gaps it you start first by making a pool of flux, a little electrical cleaner when you are done and it's good to go.
Hi, just wanted to say I learned a bunch with your video. I could not stop staring at the resin melting and the soldering wire fighting agaisnt each other. Each time you flick the tip and soldering material moves it just reminds me of huge mountain taking different shapes or hyperbolic intersection of a plane forming cones. It is so beautiful. I’ve found my craft!
you gave me so much courage over soldering . now i feel very confident on soldering anything. actually i solder lens sensors , camera motherboard, smd stuff. i feel no fear because of you . thank you. 🤗
Another one here who’s been soldering for years and this has just brought so much knowledge to my solder game. Typical approach here was just to balls more solder onto the tip when liquid soldering when I should have been using flux !!
i have built many things over the last 13 years and repaired many more over the last 20. being self taught has its advantages and disadvantages based on the circle your around. today this video has explained a problem i have been asking people and google for years. "How do i get rid of the tips"? I guess my question was to simple and i hadn't done enough research. Thank You very much for this video!!
Neither my electronic teacher thought me when & how to use flux 😑😑 But this guy thought me in 7 minutes !!!! Most satisfying video ever !!!! I think u just earned a subscriber
In other words.. flux is your friend in soldering. I've made a habit to add flux to whatever i solder and works great.. form soldering SMD's to soldering sheetmetal. Actually in sheetmetal soldering is required to use flux as the tin/lead bar does not have any flux in it. - i use borax when soldering big stuf, smd no clean type flux for smd work, and for general wires and connectors i use my blend of rosin/IPA made into a liquidy-gelly type of flux.. a lot of mess afterward but good enough for general splices and connectors.
I’ve soldered so many things in my life. But I’ve never really known why I used flux or if I should use flux. This video answered the question without even talking.
I've learned more from this video than I have from the 5+ hours of other videos out there on TH-cam. I now actually have a decent logical understanding of how things will react and what to do when I don't get the result I want. Thank you.
I clicked like 3 times I hope that many beginners will start watching this video. After watching the video, I found out why soldering didn't work well. thank you 😍😍😍
actually the flux is there to prevent oxidation so i'd say it's the exact other way around... flux when you're heating up something and then applying solder (heating up causes oxidation) and no need for flux when you're just applying the solder... i'd probably use it in both cases just to be sure tho
Oxides form in the presence of oxygen, heat not needed (but it helps). The flux is a "reducing agent", not in the "it reduces their formation", but in the Redox sense (check wikipedia for that word). It actually drives off the oxygen, turning oxides into the straight metal again.
Some don’t believe in using extra flux of any kind. What a duh idea! I can’t press the importance of extra flux use each and every time you solder. The key point in this is to use only the same type flux as the solder’s flux core. It matters not the flux’s state, liquid, gel or paste, what matters is that it matches the flux type, R, RA, RMA or others. There is also the area of starting with clean surfaces of the PCB, leads and wire. Starting clean and finishing clean is what separates the ones who understand the high quality, high reliability soldering. You cannot under evaluate the importance of flux in any case regardless of the level of involvement of your soldering. Flux use is what separates the ones who know and care from the ones who don’t know or care. Learning this importance matters as your project or your job depend on the quality of your work as well as the quantity. Extra flux is what separates the ones who know from the ones who are lost and need guidance to empower them and allow them to improve themselves.
It is mandatory to clean the flux? or only those that are corrosive? because I never heard of them causing any problems with the rosin type (in circuits that handle low frequencies). Rosin type, aka Colophony a natural pine resing. I also heard about fluxing the pcb to protect it. , I don't know... I never did.
Usually says No clean flux if it is ok to just leave it. I think Mikes electric stuff or something like that has a video explaining different types of solder and flux. I rarely remove flux and never seen a issue
+tullgutten hey thank you for sharing knowledge, to be honest I never used real natural colophony, what I used was an "activated" resin that comes in a can like shoe polish, from the brand ThermoPasty "Kalafonia, aktywna do lutowania", to be more specific. Recently I saw a video of "how to make homemade flux" and use it to cover a circuit made in a prototype pcb to protect it from moisture... Well I'm about to do several experiments with high - low frequency, high - low voltage and high - low current to see what happens, greetings
Anybody else love the music just as much as the material?!? AWESOME TRACKS this author has. I keep coming back to the vid for the music, even tho i got learned by the flux material.
This is really eye opening. Flux is magic. I wish this appeared on my soldering tutorial searches. It was only recommended to me now, ~4 months later. But never too late! I still haven't used the flux I have 😁 my solder lead has flux in it, but sometimes my joints get all messed up. So flux is the secret ingredient huh...
Instructions are hard to follow, but this is a VERY Important distinction to make. Molten vs Cold solder at time-of-Soldering. Thankyou for sharing it.
@@cookedpotato ya. case in point, i just put away my groceries and flux really helped. I'll probably use flux tomorrow also. and next time i solder after watching this use it before during and after soldering. and maybe a few times during. I should buy stock in flux.
jeebus...why didnt I know this? Havent tried it yet, but Ive sloping melted solder onto joints that wont stick for like a day now. Im thinking this might help. Thanks. EDIT: All I can say is "wow". Your advice and actually SEEING it get done, made the job simple and even possible. When I was pushing solder around not sticking...over heating the switch...turned into POW. Stick, quick and beautiful joint. It took all of five minutes too. I wanted to solder more stuff..,.just for fun. Really...thank you. Flux and a clean tip and good solder made it so much easier. I THOUGHT I just sucked. Almost gave up.

After watching the video, I found out why soldering didn't work well.
thank you 😍😍😍
1:24 The PERFECT way to show when you need flux. Bravo.
One of the basic need of soldering components, wether they are big or small.
Nice video
Fantastic my friend, thank you for the nothing left to question explanation!👍👍👍
There's something deeply satisfying about watching something being soldered properly.
At first, it's "why is this on recommended page?", but after watcing this, I've learned something good.
I learned a very important lesson from you. Thank you for sharing your knowledge for us.
i use cheap flux core solder, my connections are always perfect and it saves a lot of time.
The most informative videos on soldering I've ever seen. Great job.
only use demonstration texts and background music, but *very clear and informative*
+1 like and subcribed.

Even with flux core solder I still like to use a little paste flux. It just makes things flow so much better.
actually the flux is there to prevent oxidation so i'd say it's the exact other way around... flux when you're heating up something and then applying solder (heating up causes oxidation) and no need for flux when you're just applying the solder... i'd probably use it in both cases just to be sure tho
Oxides form in the presence of oxygen, heat not needed (but it helps). The flux is a "reducing agent", not in the "it reduces their formation", but in the Redox sense (check wikipedia for that word). It actually drives off the oxygen, turning oxides into the straight metal again.
I only see your soldering videos because it's soo satisfying to watch 🥰
oooo now i get it why people use flux when soldering microprocessor.... thanks for ur video
Great instructional video. Appreciate the simple, straightforward diagram at the end.
Some don’t believe in using extra flux of any kind. What a duh idea! I can’t press the importance of extra flux use each and every time you solder. The key point in this is to use only the same type flux as the solder’s flux core. It matters not the flux’s state, liquid, gel or paste, what matters is that it matches the flux type, R, RA, RMA or others. There is also the area of starting with clean surfaces of the PCB, leads and wire. Starting clean and finishing clean is what separates the ones who understand the high quality, high reliability soldering. You cannot under evaluate the importance of flux in any case regardless of the level of involvement of your soldering. Flux use is what separates the ones who know and care from the ones who don’t know or care. Learning this importance matters as your project or your job depend on the quality of your work as well as the quantity. Extra flux is what separates the ones who know from the ones who are lost and need guidance to empower them and allow them to improve themselves.
What a brilliant video.. Informative, concise, and imminently relaxing. Well done!
*Thank you for this very amazing and educational video...Keep up the good work!*
I can not FATHOM just HOW MUCH this video is gonna help me in the future!!
It is mandatory to clean the flux? or only those that are corrosive? because I never heard of them causing any problems with the rosin type (in circuits that handle low frequencies). Rosin type, aka Colophony a natural pine resing.
I also heard about fluxing the pcb to protect it. , I don't know... I never did.
Usually says No clean flux if it is ok to just leave it.
I think Mikes electric stuff or something like that has a video explaining different types of solder and flux.
I rarely remove flux and never seen a issue
Organic flux MUST be cleaned after what i remember
+tullgutten hey thank you for sharing knowledge, to be honest I never used real natural colophony, what I used was an "activated" resin that comes in a can like shoe polish, from the brand ThermoPasty "Kalafonia, aktywna do lutowania", to be more specific. Recently I saw a video of "how to make homemade flux" and use it to cover a circuit made in a prototype pcb to protect it from moisture... Well I'm about to do several experiments with high - low frequency, high - low voltage and high - low current to see what happens, greetings
Been soldering for car projects for yrs and i just learned about flux.. thank you so much for this video
nice ! i do not speak english but i understand yours videos
This video answered some questions I didn't know how to ask. This was extremely helpful, thank you!
2:28 relax 😌
Free Videos 👍😊
Anybody else love the music just as much as the material?!? AWESOME TRACKS this author has. I keep coming back to the vid for the music, even tho i got learned by the flux material.
So we should apply flux after soldering and then provide it heat?
Look at your join. If the flux has been used up, add a bit more flux.
Simply the best demonstration of why flux cored solder never works for me. Thank you so much.
The answer... Always!
This video helped me understand why I've never had any luck with soldering. Thank you!
Satisfying vid
This is really eye opening. Flux is magic. I wish this appeared on my soldering tutorial searches. It was only recommended to me now, ~4 months later. But never too late! I still haven't used the flux I have 😁 my solder lead has flux in it, but sometimes my joints get all messed up. So flux is the secret ingredient huh...
"When not to use flux" would be a more informative video... although I am not sure the video will be very long.
Thank you for your brief and multiexpanatory videos.. I really appreciate your way of providing the facts under exact examples..
I got this on my recommended and I have no idea what’s happening
Yeah same...
Guess i habe to learn about soldering now
Instructions are hard to follow, but this is a VERY Important distinction to make. Molten vs Cold solder at time-of-Soldering.
Thankyou for sharing it.
What does “1~3 soldering” and “>3 soldering” mean..?
soldering or repeat soldering 3 times (3:52), ">3" mean greater 3 times soldering
@@johnerin2291
I was wondering the same thing. Thanks so much for the explanation!
I took ">3" to mean soldering 3 or more adjacent joints, i.e. - "goober flux once, solder many."
this was the best explanation I've ever seen. great work!
And what of the Flux Capacitor?
Also make sure to clean your solder joints after using flux.
How?
@@jjjsmith2497 Isopropyl Alcohol and a clean brush. Then dry it with a q tip or cotton ball.
@@Daa253
Thank you very much.
My soldering has sucked for years and now i know why, lol.
you got a new subscriber haha
thanks
Really love the visual demonstrations, keep up the good work :)
5:47 *cringes in extreme discomfort
6:00 *That's better*
I guess I need to buy some flux.
yes. even if you don't plan on soldering.
@@surveyguyor8958 lol yes I totally agree it would help alot in the future
But fun fact petroleum jelly can be used as flux,
@@cookedpotato ya. case in point, i just put away my groceries and flux really helped. I'll probably use flux tomorrow also. and next time i solder after watching this use it before during and after soldering. and maybe a few times during. I should buy stock in flux.
You have some of the best soldering videos on TH-cam
what was the video i like it very much thank you so much that i thing that only that why thhe solder is happen like these
The MCN-UV80 is a incrible flux for solder, i like it !
Im glad too.
Tks very much
I always flux up my joints.
Wow this made me understand the use of flux so much better. THANK YOU!!!
Cool!
Thank you this video explains a lot, soldering is an art form
teacher.which tin, you use for these jobs
I already know all this, why is this video so relaxing?
I'm here because I'm preparing for changing my shitty logitech mouse switch
What logitech mouse?
@@MirelRC g102 the switch is omron china 10m click switch, i heard that logitech fix the issue in new mouse they replace it with 20m click switch
@@wolframazer what version is with the 20m switch? G203? I am asking because I have bought last year a g203. Until now it still works.
@@MirelRC omron d2fc-f-7n
Thanks a lot, i was asking myself too many questions that why my solder wire dry so quickly before the parts even bond. That was helpful🙌🙌🙌
finally i get what flux is for!!!!! brilliant demo, have been using flux free solder and messing up with the clingy bits driving me bonkers👍😎🇬🇧😁😁😁
I Finally understand why I always see people applying that compound! Thanks for the video! It explains why my solders are totally shitty 😭
I won't get anything better than this from internet...😮😘❤️ Just wow!!!!!!
jeebus...why didnt I know this? Havent tried it yet, but Ive sloping melted solder onto joints that wont stick for like a day now. Im thinking this might help. Thanks. EDIT: All I can say is "wow". Your advice and actually SEEING it get done, made the job simple and even possible. When I was pushing solder around not sticking...over heating the switch...turned into POW. Stick, quick and beautiful joint. It took all of five minutes too. I wanted to solder more stuff..,.just for fun. Really...thank you. Flux and a clean tip and good solder made it so much easier. I THOUGHT I just sucked. Almost gave up.
Love the flux meter- GREAT demo!
One of the best soldering tutorials on youtube, thanks !
