Abstract: A printed circuit board (PCB) has multiple layers, where select portions of one or more conductive layers, referred to as core circuitry, form a semi-flexible PCB portion that is protected by an exposed prepreg layer. The semi-flexible PCB portion having an exposed prepreg layer is formed using a dummy core process that leaves the exposed prepreg layer smooth and undamaged. The core circuitry is part of a core structure. The semi-flexible PCB portion is an extension of the remaining adjacent multiple layer PCB. The remaining portion of the multiple layer PCB is rigid. The core structure is common to both the semi-flexible PCB portion and the remaining rigid PCB portion.

Abstract: A selective segment via plating process for manufacturing a circuit board selectively interconnects inner conductive layers as separate segments within the same via. Plating resist is applied to a conductive layer of an inner core and then stripped off after an electroless plating process. Stripping of the electroless plating on the plating resist results in a plating discontinuity on the via wall. In a subsequent electroplating process, the plug non-conductive layer can not be plated due to the plating discontinuity. The resulting circuit board structure has separate electrically interconnected segments within the via.
