Dear Technetters ; Is MIL-S-13949H still effective? Nowadays, our domestic customers strongly request various thickness of prepregs and copper clad laminate for multilayer PCBs. The nominal thickness in our catalogue which is designed considering adequate resin content to styles for 2116, 1080, 7628, .... etc is not valid any more. My opinion is against to those requests that ignore adequate resin content recommended in MIL-S-13949H. But if so, quit this job ?
