Selective dielectric resin application on circuitized core layers

摘要

A layup for multiple-layer printed circuit board manufacturing is formed according to a process that includes selectively applying a dielectric resin to a high resin demand region of a circuitized core layer without applying the dielectric resin to another region of the circuitized core layer. The process also includes partially curing the dielectric resin within the high resin demand region. The process further includes forming a layup that includes a layer of pre-impregnated (prepreg) material adjacent to the partially cured dielectric resin within the high resin demand region of the circuitized core layer.
