PS For future reference, does this sort of exposed PCB trace (pad?) used for electrical connection take solder well?
I can’t tell if you have gold plate or just raw copper (probably gold. But in either case, yes, it is solderable. You can think a little bit about how they manufacture the boards. First the print on the green solder resist, then they dunk it into an electroplating bath for a gold finish, or a dunk it in solder for HASL. It would be a lot of trouble to go through (=$$$) to individually mask off that part of the board for some special process.
Is this one-piece battery-to-PCB "clip" standard (for easy replacement) or a custom piece? +PCB pad ? (discuss.tchncs.de)
