Soldering Tips (no pun intended) for Beginners!
schmitt trigger:
Excellent write up. You have covered all bases.
Very difficult to add anything meaningful to this comprehensive list, but here I go:
I also use no-clean flux for virtually everything.
However for low leakage circuits, or the ones which one requires to conformal coat to use on very humid environments, I then use water washable flux.
Wash them first with very warm tap water, and then rinse them with DI water.

Back then it was expensive to create and distribute training films, so people thought and planned what was necessary, and didn't have a lot of talking heads um-ing an ah-ing.

Thanks for the link! This is great for anyone who needs basic lessons. While my post is not meant to be a lesson and just be tips & tidbits, I'll still stick this link in there so people can go get some lessons if they feel like they need them. Great find!

Awesome, I'm glad you found my list to be comprehensive and full, as I want to make sure I cover as many bases on it as I can so I can give as much help as possible.
As for your tip, I may add that in. The only thing that I'm hesitating about is that this tip is for more advanced soldering, where a person takes into consideration the little details and environmental limitations - whereas my list is for those who don't care too much about the tiny details yet and just want to solder. I will say though, I will take your tip into consideration. Thanks! :D

You are welcome.
As previously mentioned, I struggled to add a meaningful addition to your comprehensive list.
Another tip (he, he, this was intentional ;D):
Perhaps you would like to add an advanced tips sidebar, for those occasions where you may want to discuss an advanced technique.
JustMeHere:
Solder from the tip to the joint is fine as long as you do it right. Soldering SMD almost requires this. Just use flux.

--- Quote from: WyverntekGameRepairs on December 14, 2019, 03:46:06 pm ---- Use leaded solder wherever possible. You may have heard that leaded solder kills you, but this is very exaggerated. Yes, you do have a chance of getting poisoned from leaded solder, but only if you stick your nose right up in the fumes every time you solder for about a year and then lick your fingers of the stains the solder leaves behind when you touch and rub it. You have to really ingest it and absorb it into your body for it to cause you harm. I know plenty of people who have used leaded solder their entire lives, but never had any significant health problems from it. Leaded solder is far better and safer than lead-free solder. Lead free solder has carcinogenic (cancer-causing) chemicals to make it melt better. Unlike Thallium, Antimony (one of the metallic elements used in lead free solder) is not poisonous on its own. However, when mixed with the other chemicals found in lead-free solder, it can and will become carcinogenic enough to poison you from the fumes alone. Lead-free solder is also more brittle than leaded solder, and does not make good joints unless you have melted it at the proper temperature.

Afaik the boiling point of metals is much higher than the melting one, so lead, which unlike antimony is bioaccumulative, has been banned for environmental reasons (due to poor waste management) rather than for direct toxicity. The health risk of solder fumes comes from the flux vapors and degradation byproducts.
