Depends on the solder and the component, for wires there is no way to hurt it so you can crank up for efficiency, and for sensitive components you need to be more careful.
It’s actually much harder to make a good solder joint with lead free solder, so be kind to yourself about it. No harm in re-doing a joint.
- WalterBright 4y agoYou can melt the insulation off the wires :-/ Anyhow, I never fried a part with the iron. Heated the wire just enough to flow the solder, and applied heat only barely long enough. To avoid needing a third hand for some joints, I'd pre-fill the hole with solder. Then heat it up again till it melted, and push the wire in.
- MarkMarine 4y agoYou can get a cold joint that way. I went through the through-hole solder training for lead free solder, for manufacturing aerospace components back in the day. #1 thing they teach is not to do things like that, you need to heat the component and let the solder flow to the joint around the component, never heat the solder itself or pre-solder, etc.
