hi-temp platable plastic
(OP)
Hello all,
I looking for a platable plastic thats capable of 125c. Unfortunately, PC/ABS blends are boarderline. Can any one recommend a high-temp platable plastic that is easily capable of 125c.

RE: hi-temp platable plastic
Glass filled PC/ABS might do, but the glass will give a poor finish and may induce stress that will be attacked preferentially in the plating pre-treatment solutions.
Are you plating for performance or for looks.

Plated plastic and conductive paint don't work reliably for shielding....
... not because they're not adequately conductive, but because you can't produce and maintain a reliable ground connection to the conductive film.

However, why is the ground connection unreliable. I would have a ring terminal screwed directly on the board thru the shield sandwiching the PCB conductive pad to the conductive side of the shield. You must know something I dont...can you please go into detail. Thanks...

Once you have your coating of electro less nickel or electro less copper, you can build up with any metal that can be applied by electroplating of metal to any thickness you like, so long as you are prepared to pay the price.

Eventually, you end up with nickel plated steel rimmed with rows of closely spaced fingers that are in turn mechanically held in contact with a ground plane. Or containers closed by continuous solder seams or fusion welds.
All of these wonderful, cheap, easy, quick shielding methods work just fine in the engineering laboratory. Put them together with real line assemblers and expose them to the customer's real environment, and all the money you saved on wonderful, cheap, etc. goes out again, greatly magnified, as warranty costs.
