Buried hole is a through hole between the inner layer buried vias boards, lamination, you can not see it does not have to occupy the area of ??the outer, upper and lower sides of the hole in the inner layers of the board, in other words buried inside the board The Blind hole is applied to the surface layer and one or a plurality of communication buried vias board costs inner layer, the hole in the side is the side of the board, and then through to the interior of the board of date. , Branch Snyder Department of International Ltd. Shenzhen-Electronic Technology Co., Ltd. - The Department of Electronic Technology Company is a professional custom single-pane, double sided, 2-40 layer multilayer professional providers, to provide customers with high-precision, Shenzhen circuit board quality, quality assurance buried vias boards offer reasonable prices. From a design standpoint buried vias PCB copper sink hole, a through-hole is mainly composed of two parts, one in the middle of drilling (drill hole), and second, the drilling pad area around the small decision over pore size. Obviously, high-speed, high-density PCB design, designers always want vias as small as possible, so that the board can leave more wiring space, in addition, smaller vias, its own parasitic capacitance The smaller, more suitable for high-speed circuits.
