Leaded vs Lead-Free Solder

The cluster centers on discussions of soldering techniques for electronics, emphasizing preferences for leaded solder due to its ease of use, better joints, and lower melting point compared to challenging lead-free alternatives, along with tips on tools, flux, irons, and safety.

Try soldering without flux and tell me tools don't matter ;/

Taking a guess, probably has something to do with batteries heating up and solder having a low melting point.

Good excuse to break out the soldering iron.

get a fume extractor if you solder, and especially if you desolder old boards. then, only solder with lead-free solder.

> Get leaded solder when possible.I've had good results with SnBi soldering wire - it has low melting temperature and you don't have to be so careful with hand washing (I think ;) I got mine from LCSC shipped from China, but it seems [0] you can now get it in US.[0] https://www.walmart.com/ip/Mechanic-Lead

Couldn't they just use lead solder on the IoT circuit board?

Use lead solder, like NASA does: easier to use, and no whisker issues. Just wash your hands afterwards

If you hate soldering with it, it's lead free

How does it feel to use? It's unfortunate but tin + lead solder is just better than the other options on the market.

Anybody have tips on how to get to this level of solder-fu?
