This video shows some soldering basics.
I discuss mainly the importance of getting good solder/flux coils vs bad ones. Cheap solder separates from the flux and balls up before you can really work it onto the circuitboard.
High-quality solder flows into the board where it is supposed to go. Unless your soldering iron is too hot for your materials, in which case you might evaporate the flux before it can reach the board (careful with your temperature).
I demonstrate the frustration at not even being able to solder with cheap materials.
Another issue is, for example, even if you do manage to get the solder attached, if it is balled up, it may break off like it actually did in my laptop power button.
The importance of spending another couple of dollars on good solder can't be expressed enough.
Since this video was made, I have soldered more and been tutored by the best. I would like to note that I should have tinned the iron more. Tinning means putting solder on the iron. It makes the flow from the solder to the board easier if there is more on the iron. This is the procedure: tin --> clean with sponge/metal sponge --> re-tin --> solder --> clean --> repeat.
Also, tin before putting back your iron, as a bare iron rusts much more quickly; it is fine to store it with solder on the tip.
I thought it was something about the way I was working, I've been soldering off and on since the 80's and until a couple of years ago I had never had the issue with the solder "balling up ". Now that you mention it the soldering iron set I was using was cheap!! Now I'm not having any issues since I purchased solder and flux separately and it (I felt) was a little costy (I'm Frugal?). So all the time it was cheap solder. Thanks so much.
I'm glad it was useful for you! Thank you for commenting. 🙏💝
The 1st solder didn't have flux mixed in. But I do agree they are still not good😊
Update: According to my friends at the local makerspace where I purchased the USB soldering iron, I cannot just connect the USB soldering iron into the computer or a USB adapter. Apparently, I must use a USB portable battery.
one more tip allways good clear that boards "pins" with alcohol before soldering you will not believe how its going fast. and ofc every 1 or 2 solders clean solder tip add little iron and there you go :)
Soldering is hard to do. I tried soldering my car speaker wires, because ai usually just twist wires and use glue heatshrink. The solder worked great with rosin flux on it first. The speaker wires in the car at the stereo, just dropped off. Nothing worked, it still kept balling up and dropping off, so I just used my twist method with the heatshrink. I can't solder, so I just gave up.
Hi! Sometimes, if your workflow works, it is best! Although, in this case, I guess that over time things could come apart under the shrinkwrap... Anyway, to give some explanation for what might have happened, I think you used too much rosin and contaminated your connection. I just read that solder flux, or resin, can contaminate your joints if you use too much. If you still have the heart, don't give up! Decent rolls of solder that already have flux in them (and I have used) cost $5-$7 USD. Not expensive, and you don't have to worry about using too much resin. Also, before doing a job, I practice a few times on wires and things that won't be used, just so thaty hands get the hang of it again. That way, when I do the job, I am less likely to mess up... Good luck, Chas S!
Hey.Those Cheap kits are nice that they got multimeter solderiing iron wick and some of them they got rosin flux the problem on those cheap kits is the Solder is the worst quility they put there you just througth it to the bin.That you can do is to make one nice flux 50% kolophonium Dust 50% isopropyl alchohol up to 90 degrees inside a small bottle mix it and you got a nice one flux for decades because rock rosin is cheap (not blue alchohol it will not work).The second is to buy one good solder spool 60/40 lead is around 15-20euro and that its.
Wow! Thank you so much for the recipe!!
You might also try setting the iron to a higher temperature. It's true that too much heat can damage components, but 572 degrees (F)/300 (C) might just be a little low. I usually start at about 650 degrees (F)/343 (C), with lead-based solder. Sometimes, I go higher. Keep in mind that while applying too much heat isn't good, having a lower temperature may require you to keep the iron on the pad too long, which may also damage the component.
I hope you don’t give up on your soldering. These things do take some practice but it’s a great skill to have and electronics is a lot of fun. The solder that wouldn’t melt looked like unleaded and didn’t appear to have enough flux you needed a much higher temperature. Not wanting to Be rude but the equipment your using wasn’t very good. Try to use a lead solder with a rosin flux from a known brand.
Hi! Thanks for your comment! I know my materials aren't very good, but that's the situation at the moment. I'm not giving up. The person liked their present, and it works, so I'm happy.
The only soldering iron I found which works great, which I haven't found, is the V-Type one, where you clamp the work in the iron, and it heats it up, and the solder flows perfectly on your work. That type isn't for board work tho. Probably the one I saw my friend soldering car stereo wires with it, came from snap-on or mac tools I'm assuming. It was 1991 so I don't remember too much about asking where he got it. Gotta be online somewhere, but probably has a specific name for it is why I don't find any, and probably too much out of my price range anyway !
Edit: I don't solder enough to spend that kind of money for a good one.
i just bought my cheap kit today and i am thinking of giving up already. the solder never melt like in the other videos and i am very upset :(
Yes, it is very frustrating. According to my friends who are professionals, it is very important to have good solder. My best to you.
@somnyad thank you for you advice . even if did cost me an arm and a leg. I would love if you suggested me a good brand i may use. slightly above budget no problem
@@kmdex Actually, it doesn't seem to have to be expensive. But it should be more expensive than the cheapest ones. Also, they said that the tip of the soldering iron should always be cleaned and then the solder melted onto it before use. Also it should be stored with solder on the tip, and cleaned again before using. The tips easily go bad and rust, and then they do not work properly. Please let me know if this information helps you. My best wishes to you, Hassan!
@@somnyad just saw your reply. tho i did may research before but yeah you 100% right. tip tinning is the secret about it. also my soldering iron gets carbon dioxide like crazy. really appriciate your reply and best withes to you.
"happy soldering"
