  • Multilayer combined rigid and flex printed circuits
    Patent number: 4800461
    Abstract: Multilayer rigid flex printed circuits are fabricated by a novel process to provide structures having rigid sections incorporating insulator materials which, when subjected to elevated temperatures, do not expand sufficiently in the Z direction to cause difficulties, including delamination and cracking of plated through barrels. The flex section includes flexible insulator materials which extend to but not a substantial distance into the rigid section.
