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 circuit boards, circuit boards fast proofing, quality assurance, reasonable prices. Bonded Copper PCB is obtained through the etching process. Bonded Copper has a base plate and a copper foil, ten-layer circuit board proofing, plates base commonly used insulating material such as glass fiber and covered with a layer of copper foil (usually oxygen-free copper). After etching the copper foil remaining after a section of the twists and turns of copper, these foils called traces. These trace function is equivalent to the circuit diagram of those connections, which are responsible for the pin components are connected together. Foil drilled with holes for mounting electronic components, called drilling. And for the component leads soldered copper is called pads. 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 plywood professional supplier, Guangdong circuit board, providing customers high-precision, high-quality circuit board in Shenzhen, 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 is divided into three categories, circuit board design issues, namely the paper substrate, composite substrate and FR-4 board three categories, its properties and uses are different, which is currently the FR-4 mainstream. The computer we use every day all the PCB board, and are based on FR-4 as raw material. What circuit boards, Newell record (certified), Shenzhen, Guangdong board consists of Newell Electronic Technology Limited. Newell Shenzhen Electronic Technology Co., Ltd. (www.yipcb.com) (www.yipcb.com) is a professional "pcb board" company. Since its inception, we adhere to the "good faith, sound management" approach, the courage to participate in healthy competition in the market, so that the "division Snyder, Newell a" brand has a good reputation. We adhere to the "service first, customer first" principle, so that record Newell won the trust of customers all of the printed circuit board, and establish a good corporate image.
