Need plating on ceramic boards. | 31 August, 1999

****************************************** ***************** HELP! *************** ******************************************

We are having a special ceramic smt board made. The boards are 16-up arrays that have smt pads on both sides. Only three vias per board from side A to side B. We have located a ceramic facility that can score the ceramic as needed, put down the thick film Silver pattern and pull it thru the vias for conductivity. The panels are 4.5" x 4.5" x .040" alumina.

We NEED a plater that can plate on: 50 micro inch Nickel, then 0.008" Copper (+/-.002), then 75 to 200 micro inches Nickel, and finally 200 to 500 micro inches Tin.

ANY help would be greatly appreciated.
