Abstract:
1. A double-sided printed circuit board comprising: a single flexible circuit material including only two circuit layers, a first circuit layer and a second circuit layer, wherein the first circuit layer is on a first surface of the flexible circuit material and the second circuit layer is on a second surface of the flexible circuit material, wherein the second surface of the flexible circuit material is opposite the first surface of the flexible circuit material; an unclad rigid material coupled to the flexible circuit material through an adhesive material on the first surface of the flexible circuit material, wherein the rigid material acts as a stiffener for the flexible circuit material; a first opening in the rigid material extending from a top surface of the rigid material to the first circuit layer of the flexible circuit material; and a second opening in the rigid material extending from a top surface of the rigid material to the second circuit layer the flexible circuit material, wherein the second opening includes a generally uniform width from the top surface of the rigid material, through the flexible circuit material, to the second circuit layer, and wherein the second opening is sized and shaped to allow a first electrical component to be situated in the second opening.
