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, reasonable prices electromagnetic compatibility is an electronic device is still able to coordinate the various electromagnetic environments, the ability to work effectively. The purpose is to make the electronic device can inhibit a variety of outside interference circuit board electronic module, the electronic device can work in a specific electromagnetic environment, while reducing the electronic device itself electromagnetic interference with other electronic devices. 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 quality phone module circuit board circuit board, quality assurance, 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 circuit board module combines power, then it must be a 6/8 shelves. If you can find, nature is 4 layers. In multilayer PCB circuit board module, 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.
