Need Plating on Plastic? |
|
![]() |
Letter 6038 Twin moulded non conducting plastic also getting plated.. We have received a twin material ABS - polycarbonate logo to be Satin nickel plated only on the grey ABS portion. Our problem is that the blue polycarbonate, supposedly nonconducting material is also getting partially / fully covered with plating. What are we doing wrong ; is it the chromic acid etch, or the silver nitrate based activation or the electroless copper. How can we avoid coating the blue polycarbonate ?
I think the only real difference between ABS and polycarbonate from a plating perspective is that ABS etches better for better adhesion of the plating; there is nothing inherent in the polycarbonate that prevents it from becoming activated and getting plated. I haven't worked on a similar job, so I could be completely wrong, but I don't think you'll solve this problem through chemistry adjustments, but only by masking at some point.
