Splet11. apr. 2024 · A via is a copper-plated hole that creates an electric connection between different layers of a PCB. Normally, any type of via such as through-hole, microvia, blind, and buried can be filled. First, the hole wall is plated to make it conductive. Later, the barrel is filled with conductive (copper) or non-conductive (resin) material. SpletThis is a common type of Xbox One controller PCB. It has one conductive copper layer above the substrate and electrical parts on a single side of the board. Besides, conductive paths cannot intersect or overlap in single-sided Xbox One controller PCBs. Double-sided Xbox One controller PCB.
