Topic: Copper thickness

Why does de the strike bath, rochelle and acid copper have different layer thickness?

Strike up to 2.5 microns

Rochelle up to 8 microns

Acid or High efficiency:  any


It is because beyond this thickness the coating is spongy?

Re: Copper thickness

I believe it has to do with bath efficiency.  As the bath efficiency goes higher, the rate of deposition goes up as well.  I suppose you could plate any thickness in a strike bath, but it may take you a significant amount of time.  If I had to guess, I would say that the thickness rating given on the chart are just suggestions.
