Ohh kayy. Unleaded solder melts at a higher temp, which is more difficult to generate/maintain. The higher temp can damage components. Additionally, unleaded solder can produce tin whiskers over time.
I get that leaded solder is easier to use, but just because something is easier does not make it better. It’s possible that 0% of the aerosols generated by leaded soldering contain lead particles (although it’s more likely the low end of a distribution), but you’re still introducing lead to your body by handling it and the environment by using it.
I’ve heard plenty of arguments against unleaded solder at IPC and IEEE events, but they exclusively come from professionals who have been in the industry for a long time. I’ve never heard a single person from a younger generation of EEs advocate for leaded solder.
I can see you fall into that category. I completely respect your opinion, and I value any insights you can provide. Recent and prospective EEs cannot grow in this esoteric industry without help from people with your level of experience. I just wish you would frame it as:
“I prefer leaded solder because X, Y and Z. Try it out and make an informed decision for yourself”
Rather than using your position of experience and authority to assert your views by making claims like
