ABSTRACT:
Rigid-flex printed circuit boards (PCBs) are fabricated by an improved and simplified process to form the PCBs from rigid-flex PCB subassemblies with both rigid and flex sections incorporating suitable insulator materials. The flex sections of the PCB subassemblies are protectively covered by insulating layers formed by deposition of a liquid precursor for the insulator material and curing of the liquid precursor to form the insulating layers.
