I have here two different pieces of copper that are from a standard [inaudible 00:09] power supply. One common soldering job might be to put a connector on something like this.
This piece of wire has been stripped and sitting out in the air for a long time and I wanted you to see how it looks when compared with something that's just recently stripped. And holding them side by side, you can see that the one in my right hand is much, much cleaner and shinier. It has a pinkish appearance of nice, clean copper whereas, the one on the left not as copper colored.
The copper that has been exposed to air for a long times forms an oxide layer on its surface and that oxide layer tends to disrupt the alloying process of soldering. So it's important to be able to get rid of that oxide layer before you begin soldering.
There are two ways to do that. The first is to mechanically remove it. You can do that by using sand paper to abrade away the oxide. And the other way is to chemically remove it and for that, we would use our rosin core.
So let me show you how it looks when we tin solder to the clean copper wire. Begin by adding some rosin, placing it in our vice, and heating it with our iron. See the smoke forming as the flux burns off and we have a nicely tinned piece of copper.
Now, if we try to do the same process with the oxidized copper, we're going to run into trouble. Add our flux. Okay, here we go. Now, as we heat the joint see that our solder is still tries to find its way in there. It doesn't make quite the same contact that we had with the other. Just for comparison, I'll hold them side by side. You see little bits of brown left over? That's copper that hasn't been properly soldered and the reason for that is the oxides that have formed on its surface tend to disrupt that alloying process. So in order to make a better solder joint, what we need to do is we need to remove that oxide layer.
What we'll do is we'll cut a new piece of wire. Strip and use our sand paper. Twisting the wire. Adding our flux. Applying heat and our solder wicks its way between the wires for a nice, clean tinned copper wire. And there you have it. - Навчання та стиль
After I watched this video, I went back and took apart all the wiring I ever did and fixed it the proper way....Thanks a ton!!!
More like common soldering mistake
was gunna say. where is the second or third mistake?
The biggest mistake here is the lack of a understanding macro shots with the camera.
+Scott Rader I was thinking similar, especially because so many people use phones/tablets. On my PC maximizing the screen helped satisfy my curiosity.
+Scott Rader Lls!
honestly, using auto focus on something that lays within a set range may have made this worse... it isn't tracking the focus points well at all XD
I just spit toothpaste everywhere.......
I needed that..... 😂😂😂😂😂😂
@@matthewlunatick420 it's useful information and I appreciate their effort, but integrity of instruction with something this detailed warrants the need for super sharp visuals.. glad you got a kick out of it; just wanting them to improve for next time
"Common Mistakes". Only saw 1 mistake. I guess the other is the camera work. Anywhoo thankies for the video, I'll keep it in mind.
Someone get this guy a book on soldering, macro camera work, and how to cut sandpaper into small pieces.
A bigger mistake was going through all the trouble, time and energy "sanding the wire" instead of just snipping the end and stripping off the insulation and having a nice fresh end to work with.
Sometimes you can't do that, so he's showing how to fix it.
I can't see how people find fault with this video. It is fine. The man did a good job of explaining and demonstrating the process. I know more than I did before. Thanks.
It's the internet. People find fault with everything... :(
Just kids that are pissed off that it didn't work the first time they did it, so they blame the guy.
I learnt stuff even though it was pretty badly made. It's understandable how it isn't exactly up to a great standard, but still sort of helpful.
the title implies that the video is fairly comprehensive about soldering mistakes, and that it describes more than one type of mistake.
but it doesn't deliver.
I'm an EE with a PhD in flux rheology and another in soldering alloys. I have over 40 years of professional experience soldering everything from hand-built custom spy satellite motherboards to sonar modules in nuclear subs. The tool I use the most is a soldering hydrogen torch with an iridium-plated tungsten tip. I usually clear oxydation by sweeping the wires and components with a YAG laser under a nitrogen atmosphere. If I'm soldering underwater, I prefer to use a focused induction or an ultrasonic tip depending on the salinity and oxygen concentration of the water. If I'm soldering for space, I usually solder with an alloy of 74% gold, 24% lead and 2% tin to prevent ionisation damage. I think this video was ok for beginners even if it ignores a few more advanced techniques.
i like cereal
yeah the only way to cook breakfast is by using a top secret automated kitchen that the military is developing. everybody else is a chump and should just jump off a tall bridge.
As the aim of this video seems to be to find and point out the common soldering mistakes committed in it, I found another one (I believe) not mentioned by others below: he talks about 'the alloying'. There is no 'alloying' when you solder. If there was the process would be called 'brazing'.
"Next week, on howcast, we'll learn how to use manual focus on a camera" lololol no, but seriously these videos are actually very helpful thank you for your help :)
Mistakes? There was only one, you watch this video expecting more than that.
May be the second mistake was exactly what you are pointing out :) Nothing to do with soldering though, so that would be yet another one, so now we have three.
Dude, just cut off the end that has been exposed for a while. :)
+Just a Visitor This is not always possible, for example when repairing already existing electronics that would result in the wire being too short if you cut the tip off and having to revire the entire thing in such case.
+Strazdas then solder in more wire
Neil Etnyre Well i guess that is a solution, but then you end up with two solder joins instead of one and solder is brittle so it cannot bend like wire does.
Didn't the guy cut and strip a new end in the video?
Never understand why people take the time to post negative comments. I found the information to be useful. My only problem is that the wires want to join are very thin and difficult to get free access to.
Or you could just cut and strip a fresh wire further down the wire ._.
Or keep your wires nice and moist inside your girlfriend.... Also a good solder iron holder..
Not when you need specific lengths and the wire is not replaceable.
or you could watch the whole video and realize he did just that!
This would have been 300% more informative if you had used a cameraman (or camerawoman) who knew how to pull focus. I'm going to guess they didn't know which direction the lens focuses because they went the complete opposite direction before focus hunting. Now, different brands turn different directions (Nikon goes opposite of Canon) so I could understand being used to one brand. Also, they need to be using a bigger monitor screen than the built in 3" on the camera. Even focus peaking on Sony Nex's don't get super thin depth of field when using 50mm 1.4 lenses. Drop it down to f/2.8 so the solder doesn't look like he's holding an earthworm.
I have a coin I wanted to make into a necklace but when I try soldering it (I never tried soldering before it seemed straight forward) the solder on the neckhoop thing and the coin kept on slipping off and wouldn't stick to the metal so I'm looking around trying to learn the basics
Videos like this are the result of huffing too many lead solder fumes.
ok i have headphone wire burn off the lacker and what im left with is oxidized black copper with bur residue how do i prep it for soldering
You guys really screwed up this video to the point where the visual information is hardly helpful at all. First, you're not zoomed in enough on the area of interest, namely, the end of the wires. They are barely visible. Second, the autofocus is jumping all over the place as you move the subject in and out of frame. Since you are focusing on a single object at a fixed distance, you should manually set the focus for that distance and leave it there.
They could also fix the f/stop to a smaller apature (eg, bigger number, 11, 13, 15) and bring in more lights to compensate.
Yes, they would lose the blur background. but since they can't keep a set distance from the lens, we might as well have more focus range to play with.
I was having a hard time soldering 0.1mm jumper copper wire, I didn't know even coated copper could oxide. Just rubed some sandpaper and solded like magic!
Yes, I am learning, but tips like this makes huge difference, I don't know why there is so much shade in the comments, that tip was superb to me. I assume people on the microsoldering field don't want competition and is always throwing hate on people that teaches these stuff, that is nasty.
I never solder with wire up. Good chance solder will flow under jacket. Always downwards or sideways. Great video. Always learning.
do I need the rosin puck if the solder wire has a rosin core?
The reason I found this was a google search regarding non-corrosive flux for soldering stranded copper wire; The problem if have found is that flux "no clean" tends, through capillary action, tends to wick up the strands, inside of the insulation, leaving blue-green corrosion of the strands, inside the insulation (discovered when disassembling/stripping insulation). To date, have been using Topnik RF-800... applied very sparingly with syringe... station temp set to about 290C, using Sn60Pb40 (SW26/3/2,5%) fluxless solder.... use IPA to clean fingertips, prior to twisting strands together... acetone seems to make the situation worse.
Anyone know how to solder stranded wire between two EL wire cables so that it goes EL wire, stranded wire, EL wire, inverter, power?
hello hope you respond to my comment i have a problem when i try to solder microphone wires small thin wires with colored insulate the thing is ... solder does not stick to them it keeps falling off i have no problem with other copper wires but with these it's a nightmare
whats a good soldering iron to buy for jewellery ?
Interesting knowledge :) thank you very much
Thanks! Very informative.
how long did you leave the solder iron to heat up ?
Help I melted off the copper contacts off the circuit board because i kept re-applying the soder wtf do i do?
Or you could use a more aggressive flux. A wire (unlike a PCB trace!) can handle it. Then was off the residue and you're done.
I have been soldering over 50 years but I have probably made that mistake ,it's a good refresher video thanks
Why go to the extra step, hassle and mess of goopy flux when all the solder I've ever seen has flux already in it?
Why not simply strip away the sheathe and expose a new wire?
Thanks for sharing video.. Makes sense and to the point.. cheers
I watch this video when I need to fall asleep thanks!
Great info!
Nice, but how do you solder to bare metal upside down?
You can see the one in my right hand.... NO.. no we can't HOLD STILL!!!
Is that Candy Crush music in the background??? Sweet!!
Another mistake was twisting the wires. You only need to follow the twist, not bulk it up. His soldering was just about OK!
u could just use resen core solder
Could you not just cut off and strip the end to expose fresh wire??
Not when you are working in a situation where that is not possible.
if the wire housing became permeable from oxygen/light exposure, then the whole length of stranded wire will be pretty well oxidized and stripping it will be a fools errand.
A common mistake is using a conical tip.
Didn't see him join the wires, plenty of room for error there.
what kind of soldering iron tip is best? I go through a tip about every 2 weeks. I use a soldering iron about 1 hour 5 days a week. I did find out tho that my solder that I was using had acid in the core.. oops. besides that, are you supposed to get more time out of a tip?
+Alpha Nerd
Make your own tips, save money. Search DIY solder tips on youtube.
They are all made the same way, essentially. Some expensive tips use more iron coating on their copper core tips. But, copper DIY tips will work. You just have to learn how to care for the tip better to get longer life out of them.
James Pian I have tried that in the past. I don't like the way the heat transfer is changed. It just doesn't work for me. I would rather pay $1 a piece for them.
+Alpha Nerd im very happy with this one , 300 degree in 4 second From DC plug,
but you need 24 V and 3 A www.banggood.com/TS100-Digital-OLED-Programable-Interface-DC-5525-Soldering-Iron-Station-Built-in-STM32-Chip-p-984214.html?p=J031143423240201512X
I work for a company that manufactures circuit boards, so I solder every day (five days a week). I usually replace my tip every few months... it just depends on what you're doing, how often you tin the tip, how you take care of it, what kind it is, etc. A couple of weeks seems like a pretty short amount of time, though.
Rachel Bonneau Thanks for the reply! I figured out what the issue was. I was using a Weller iron. It seemed that there tips did not last long. Although it was also mainly to do with the fact that after I looked back at some of my joints, I saw a lot of cerossion. So I looked at the roll of solder that I was using (my dads 20 year old roll that was sitting in the basement and he swares he was using it for CB radios) and turns out there was acid in it. So after I got a new craftsman and was dilligent with keeping it in tip top shape, I got around 2 months per tip out of it like you said!
What? You are a professor?
I have been soldering for years and have done thousands of solder joints and I recently tried to solder some copper wire that I freshly stripped only minutes before and even with flux the solder would not stick to the wire!
im trying to solder a wire very small it wont just stick to the wire
You never tinned your iron tip.
If you listen to him for a while he starts to sound like Kermit the Frog.
where did that fume extractor go????
When you get your flux, how do you turn it into a liquid? because I bought one that was in a round container and isn't melted. So are you supposed to melt it somehow?
+Venture Foro You just dip your wire strands into it
+Venture Foro Sometimes Flux crystalizes (especially if its been stored coldly). thats ok, just heat it up a bit and it will become semi-liquid. Ive seen people even using the soldering iron itself for this exercise with fine results.
yeah I dip the soldering iron into the flux really fast and it melts a lot a flux for the job. thanks
Wouldn't the flux contained in solder take care of it?
Normally yes; most solder contain sufficient flux within the core to not need any additional.
But for some special projects, such as those involving surface mount components (SMC) in which you're working with microscopic multitudes of leads, additional flux might be necessary.
Same rosin like what you put on a bow for a stringed instrument?
nope. it's tree juice.
Does anybody know if I can use a paperclip for solder?
if you melt the paperclip i guess but youd probably melt everything else
No, solder is made so that it has a low melting point
+BuddyBros255 an average soldering iron does not heat at high enough temperatures to melt a paperclip.
thank you!
Doesn't flux remove the oxide already? If you've got flux, do you really still need to sandpaper the wire?
Ive never sandpapered it. It seems like a minor factor as to the quality of your soldering
so now what? How do we get them soldered together?
transcript: [inaudible 00:09] "wall brick"
Just please use a more deeper DOF when shooting that type of a close up video ..
sandpaper to clean multistranded wire ?
using flux with flux cored solder ?
just lol
dunno what you do for a living but it's not soldering
How are you able to determine that the solder wire had a flux core?
He said it was rosin cored solder in the video. He didn't seem to know that rosin IS flux right enough.
+nexus1g
if you can't infer from him calling the tub of goo both "flux" and "rosin" that the rosin cored solder has flux, then you've got issues.
I thought this video was supposed to be about common soldering mistakes... not oxide layers or whatever.
All clean
could have used this tip in my electronic fabrication class
Didn't quite understand, so what would be the chemical removing of oxide here?
I believe its the flux that removes the oxide and then allows a clean contact to solder.
RideRedRacer
Oh, right. I missed it, I thought he showed the flux, but then took something else -- English is not my native language.
+TrueBlogge777
I thought I understood it, but now I am back again to this video, and I believe I now finally REALLY understand: what confused me is the guy in the video saying that one of the two ways of eliminating the oxide layer is a "chemical one" - with rosin (flux, as I understand), but then goes on showing us the opposite - the rosin didn't do anything to that oxidized wire.
So you are saying that he meant that rosin could only help to eliminate oxide layer from a relatively clean wire? If that's correct, then it wasn't very wise of him not to mention this little detail...
Crazy... Is it just me or his explanation was indeed kind of confusing?
it didnt mention any soldering mistakes did it?
Why not just cut the end off? You'd only lose a cm of wire.
I agree with cutting the end off, makes sense.
Since you are getting new clean copper after doing this, why would you need to sandpaper it??
+Chris McTavish you don't always have a cm to spare
+Chris McTavish you don't always have a cm to spare
Yup that's also thing with my full time job, im soldering sockets and other stuff and wires come to me in specified lengths, so they need to stay in that dimensions no cutting or some other crazy stuff... lel
That´s what she said...
Sorry, are you saying Sorder and Sordering? with an R?
Thanks for sharing video.. Makes sense....
My soldering iron tip is not working propperly like when it was new.
How do I prevent this and how can I make it good again?
keep it clean
use a wet sponge to remove oxides that have formed on it and then put some solder on it before using it
Felix St
Okay strange I have done that every time with my new soldering iron
dip the tip in the flux then dip the wire in the liquid flux apply solder it worked for me
awesome . Thank you :)
What do you call that tool? 1:24
The worst camera man EVER!
Why am I getting a soldering lesson from kermit the frog?
+Macaullay Hall LOL
Thank you
Step one learn basic photography first. Camera / phone on fixed mount. Light colored background.
I cannot solder copper wire to my magnets... its slippery ... so cant you teach me
it was a weird prop. for me thanks a lot :)
I remove the layer with a knife , just scrubbing gently at the wire , does the same thing
Nice
I thought you needed to add flux to the soldering iron. That maybe was a worse mistake than the oxidation.
Best solder I used is 50/50 lead and tin
5th?
Isn't the flux there to help clean the oxide layer off??
Flux can only do so much. The black bits is the oxide, which should be cleaned away.
please set your camera to manual focus or switch it to Macro -_-
11th?
nice tutorial 8th
Why use flux when it is already in the solder......
Graphic soldering stand
Sodder?
"Mistakes" means many of them... like in plural....
How do I solder to a smooth metal surface!?
Depending on the metal, you may have to use a high acid content flux and solder and also rough up the area to be soldered. I think flux for copper piping is quite acidic.
@@anthonytaylor8465 The metal in question is aluminum.
@@voldy3565 sorry it's a little. But at work, we have to solder earth leads to aluminium and we abraid the surface and use high acid flux. Something called Rx I think
awesome video, screw the haters. let them make their own videos
Insulting comments are like publicity. And bad publicity is good publicity.👍
Mistakes?
am I old ? where is my glasses? it's so blurly.
1:07 clean copper wire? I can solder it easily even without flux.
How so?
Cut away and solder again, what make you so difficult?! 💥😡👊🏻
