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?

Thanks for your help
