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 is single-sided double-sided circuit board manufacturers to extend, when a single-layer wiring can not meet the needs of electronic products, it is necessary to use a double-sided. There has sided copper traces, and can pass through the hole to guide the line between the two layers, so as to form the desired network connection. Multilayer means insulating material having three or more conductive pattern layer therebetween to separated laminated, and during which the conductive pattern of the printed circuit board interconnections required. Multi-layer circuit boards of electronic information technology to high-speed, multi-function, high-capacity, small size, thin, lightweight product development direction. Board by feature points, then into soft board (FPC), hard board (PCB), Rigid-Flex PCB (FPCB). 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, professional supplier of circuit board testing the quality of 2-40 layer plywood, to provide high-precision, high-quality circuit board in Shenzhen, quality assurance board, at reasonable prices. Modern double-sided PCB board material is copper clad printed circuit board type, also known as CCL (Copper clad laminate) CCL. CCL is the core of the PCB. CCL depending on the substrate material is divided into three categories, namely, paper board, composite substrate and FR-4 board three categories, its properties and uses are different, which is the current mainstream FR-4. The computer we use every day all the PCB board, and are based on FR-4 as raw material. Flexible circuit board _ _ Newell record board is supplied by Shenzhen Electronic Technology Co., Ltd. Newell.
