Abstract:
1. An electronic device comprising: a substrate; a circuit layer on said substrate and comprising at least one solder pad; a liquid crystal polymer (LCP) solder mask on said substrate and having at least one aperture aligned with said at least one solder pad; a fused seam between said substrate and said LCP solder mask; solder in the at least one aperture; at least one circuit component electrically coupled to said at least one solder pad via said solder; a first dielectric layer stack comprising a first plurality of dielectric layers on said LCP solder mask and having at least one aperture aligned with said at least one solder pad; a first LCP outer sealing layer on said first dielectric layer stack; a second dielectric layer stack comprising a second plurality of dielectric layers on said substrate on a side thereof opposite said LCP solder mask; and a second LCP outer sealing layer on said second dielectric layer stack.
