Hi Technetters, I am trying to get opinions on how to do electroless copper plating on BT and Teflon materials. Specifically, what are the parameters that I would have to change in my current process for the new materials, or do I have to consider a totally new chemistry. We are currently running Shipley 3000 electroless copper. Any ideas are welcome.
