@HopelessDemigod @vk6flab yeah, I know, but it's _luxury_ toxic waste. Sigh.
I wanted to go lead-free, but felt snookered: I’ve already used leaded solder, I need to fix those joints, and the board has an almost belligerent lack of thermal relief. If I mixed leaded and non-leaded solders in these holes, I fear I'd end up with some weird amalgam I'd never get out.
@vk2tty @HopelessDemigod @vk6flab I use classic 63% lead solder with the highest flux percentage I can find for everything. I ignore whatever might be there already. Never had a problem.
If I need to solder steel or stainless steel or nickel I use Ruby flux and my regular solder. No problem. People are stunned to see me solder copper wires to stainless steel dinner forks, nickel plated US quarters, US nickels. Easy peasy.
