Greetings everyone, I have two customers, both of whom use pulse plating to fabricate boards. One has a continuous copper deposit and the other has multiple bands or layers of plating - very visible after microetch. The plating deposit on the banded product has cracks after Thermal Stress. In my limited experience I have not seen pulse plating result in such definite bands. My question is - would bands be expected and "normal" in some pulse plating operations?
