Low cost PCB through-hole plating
Ricardo Trombetta shared a tutorial on how to plate the holes using copper hypophosphite pyrolysis to activate the holes:
This video shows how to activate a PCB holes surfaces before electroplating. The holes are activated using a low cost copper hypophosphite based solution and the electroplating is made using an acid bath that is copper sulfate based.
