Branch Snyder Department of International Ltd. Shenzhen-Electronic Technology Co., Ltd. - The Department of Electronic Technology Company is a professional custom single-sided, double-sided, 2-40 layer plywood professional supplier buried vias board Which is good to provide customers with high-precision, high-quality circuit board in Shenzhen, quality assurance, reasonable prices. In the four-layer board, the two layers in the middle layer is mainly used to take the power supply (VCC) and ground (GND) of buried vias boards superiority, board member if more density, then the inner layer can also take some general The signal line can be used in the main element layer (the main element layer is typically at the top level) of the adjacent inner layers do strata, the whole floor for copper, then another inner layer used for the main alignment layer, the second element layer (sub-component layer is typically at the bottom) can also take some lines, Branch Snyder Department of International Ltd. Shenzhen-Electronic Technology Co., Ltd. - The Department of Electronic Technology Company is a professional custom single-sided, double-sided, 2-40 layer Multilayer professional supplier, to provide customers with high-precision, high-quality circuit board in Shenzhen, quality assurance, reasonable prices. From a design point of view, a through-hole is mainly composed of two parts, one in the middle of drilling (drill hole), and second, the drilling pad area around buried vias boards, determines the size of small vias . Obviously, high-speed, high-density PCB design, designers always want vias as small as possible six buried vias board, so the board could leave more wiring space, in addition, smaller vias , its own parasitic capacitance is also smaller, more suitable for high-speed circuits.
