Jan 13, 2023 at 12:20 comment added Criticizing Israel not allowed @TQQQ look at how plumbers solder copper pipes with a blowtorch! not sure if you can do that without hurting the PCB, but still
Jan 12, 2023 at 21:57 comment added Tim Williams @TQQQ With suitable equipment of course, wave soldering for example. Reflow soldering may be feasible. In my lab, I might use a hot air machine and soldering iron or two, maybe fiberglass insulating pads on the busbar to keep it hot; a torch can even be used, with great care not to burn the PCB or rosin/flux of course.

Jan 12, 2023 at 21:20 comment added Tim Williams Yes, I would prefer copper myself, preferably tin plated. Or brass or bronze I suppose, given enough cross section of course. Then bolted or soldered connections are fine, with no particular precautions.
Jan 12, 2023 at 20:58 comment added Mołot @TQQQ if you can solder them then yes. If you can't solder them, then at least you would experience less of a problem with copper to copper connection. Copper in the bars and on the PCB will have almost the same thermal expansion, for example (affected slightly by PCB substrate and bonding to it, and yet so slightly by different level of impurities). Copper is also regarded as much less prone to creeping. Thus, risk of oxidation would be much lower. And it oxidizes slower. Of course, precautions are always a prudent idea.
Jan 12, 2023 at 19:16 comment added TQQQ So would this all be solved by copper bars instead?
