Hi Guys, Time for my silly question that requires silly answers (or not so silly answers). Is there a MIL Spec approved OSP, preferably one that works? Don't ask me which MIL Spec. but you could share that info. We intend to use this on copper over polyimide film. The copper would be electro depostied foil.
