Wolfgang -

There are a number of fabricators that can do selective plating for high
current areas of a PCB. One, I have worked with, claims to be able to plate
up to 0.031" thickness. Contact me off-line if you need contact information
I will see if I can find it.

        Subject:        [TN] boards for high current loads

        Hello

        I have a number of requests on my desk where customers need some
areas of
        boards with very thick copper (6 to 12 ounces for some heavy duty
current)
        and the rest of the board with standard fineline features.

        Heavy duty plating ?? double imaging ?? etching through a bunch of
copper ?
        none are attractive options.
        Any and all ideas on alternate processes would be appreciated.

        Thanks, Wolfgang
