silvering circuits…

I’ve gotten pretty good at cutting circuit boards on the CNC mill, but soldering to the bare copper is difficult. Someone on the pcb-gcode forum suggested Cool-Amp silver plating powder. Victor just cut a circuit board for his experimental dot matrix mind control rig, so we decided to try it. Here’s what the plated board looks like:

He’s soldering it up now, I’m curious to know if it’ll be any easier to solder. The powder was a little $, but each application only takes a minuscule amount, so the 4oz container I bought should last for hundreds of boards.


UPDATE: It worked great! Some pics:
