Snyder International Ltd. Shenzhen Branch Newell Electronic Technology Co., Ltd. The company is a custom 2-40 layer PCB board professional supplier of sheet main services provided are HDI boards, finger board, Bluetooth module board, half plate, through the orifice plate, rigid-flex board, plywood and other series of panels, printed circuit board appear before the interconnection between electronic components are relying on direct wire connection to achieve. And now, the circuit panel just as effective experimental tools exist; printed circuit boards in the electronics industry has occupied the position of absolute rule. 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 computer motherboard and graphics card mostly use 4-layer PCB board, there are some 6-layer circuit board recycling, or even 8 layer board. Vias (via) we just mentioned circuit board design, if used in the double-sided board, then they all went through the entire board. However, in the multilayer which, if you want to connect some of the circuit board, the pilot hole will waste space some lines of other layers. The use of buried vias (Buried via) and blind holes (Blind vias) technology to avoid this problem. Blind hole is connected to the surface layers of the internal PCB PCB, do not have to penetrate the entire board. Identification of the printed circuit board buried vias only connect internal PCB, so just do not see from the surface of | Yunnan board | Newell Newell hit by the Shenzhen Electronic Technology Limited. Newell Shenzhen Electronic Technology Co., Ltd. (www.yipcb.com) (www.yipcb.com) strong, credible, a printed wiring board in Shenzhen, Guangdong and other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Newell invasive and you hand into the brilliant, for a better future!
