I’ve been looking everywhere for flexible copper sheets to do flex PCBs and would definately buy a lot if it become available on SF.
Doing research all I can find is flexible copper laminate often called Pyralux, Kapton, DuPont, Polyimide copper-clad or flex copper. However, I cannot find any of it for sale anywhere. The only thing I can find is Kapton tape with single sided copper, but with it being tape it is only 18mm wide, and extreeeemly expensive.
Does anyone know anywhere that sells flexible copper sheets for home production?
