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. Modern materials are double-sided PCB board CCL, also known as CCL (Copper clad laminate) CCL. CCL is the core of the PCB. CCL depending on the substrate material into three categories Guangdong circuit board, respectively, the paper substrate, composite substrate and FR-4 circuit board substrate principle three categories, its properties and uses are different, which is FR-4 the current mainstream. The computer we use every day all the PCB board, and are based on FR-4 as raw material. Branch Snyder Department of International Ltd.

For ordinary graphics card and motherboard, the use of 4 layers can basically meet the needs. 6 laminates and cost about twice as 4-layer board. 8 layers is four times the 4-layer board. So most manufacturers are in a 4-layer PCB. This is to some extent, is a cost, but the expense of solution stability. Because if you use 6-layer, you can have ample wiring space, there are more ground and power supply options being considered. So do not be too harsh on the alignment too closely. Thus, electromagnetic interference between line width and line will be fully taken into account. Stability board naturally much better than 4 layers of similar products. Of course, it also depends on whether the products are brand-name manufacturers gold extraction circuit board, because the wiring engineer level is also crucial. So many times, small factories 6-layer product will be much worse than the 4-layer board manufacturers. 8 laminates because many layers, the wiring is relatively difficult and therefore, it is difficult to consider very well. Therefore, with the exception of some giant's flagship graphics card, 8 layer product is still very small.
