The disclosure relates to systems and methods for using additive manufacturing techniques for fabricating ball grid array (BGA) surface mounting pads (SMP), and surface mounted technology devices (SMT) package sockets. More specifically, the disclosure relates to additive manufacturing methods for additively manufactured electronic (AME) circuits such as a printed circuit board (PCB), and/or flexible printed circuit (FPC), and/or high-density interconnect printed circuit board (HDIPCB) each having integrated raised and/or sunk BGA SMP, and or surface mounting sockets for SMT device(s) defined therein, and methods of coupling surface mounted devices such as BGA and/or SMT thereto.

A circuit board is manufactured by mounting a first circuit layer, mounting a conductive bump on the first circuit layer, covering the first circuit layer with a first dielectric layer which exposes the conductive bump, mounting a second dielectric layer on the first dielectric layer with a second dielectric layer opening that exposes the conductive bump, and finally, mounting a second circuit layer on the surface of the second dielectric layer and in the second dielectric layer opening. Since the surface roughness of the second dielectric layer and the second dielectric layer opening is low, it is unlikely to form nano voids between the second dielectric layer and the second circuit layer, and the second circuit layer may be attached to the second dielectric layer firmly, which is an advantage for fine line circuit disposal.
