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 providers, to provide customers with high-precision, high Shenzhen circuit board quality, quality assurance board image at reasonable prices. Subsequently, there were plywood, it can greatly increase the wiring area. MLB spend more single or double-sided circuit board. A few pieces of plywood using double-sided, and put a layer of insulation after sticky prison (nip) between each board. Board layers on behalf of several layers separate wiring layers, layers are generally even, and includes the outermost layers. Common are 4-8 layer structure, but technically it can be done close to 100 layers of PCB board 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 circuit board proofing professional supplier, to provide customers with high-precision, high-quality circuit board in Shenzhen, quality assurance integrated circuit boards, and reasonable prices. The difference between 4-layer laminates and 6/8 way is by observing the blind hole. Because the graphics card and the motherboard used is 1,4 layer 4-layer alignment, the other layers for other purposes (ground and power). So, with double plate as a guide hole will be pierced board. If some holes in the front panel appears, but could not find the back of the board, then it must be a 6/8 shelves. If you can find, nature is 4 layers. In multilayer PCB, in addition to the alignment layer, in general, the whole floor will have a direct connection on the ground and the power supply. So we will be classified as such layers power level (Power) or ground plane (Ground). If the parts on the PCB require different power supply, generally have two or more of such PCB power and ground layers.
