The circuit schematic, with a variety of specific symbols representing different electronic components, and connect them with lines. An electronic engineer can clearly see the circuit works and the various functions of each part and connections through these symbols. If the circuit design is correct, then four gold-plated circuit boards, you only need to prepare the necessary electronic components, then connect them with wires can work Section Snyder Department of International Ltd. Shenzhen-Electronic Technology Co., Ltd. - Department of Electronic Technology Company is a professional custom single-pane, double sided, 2-40 layer multilayer professional providers, to provide customers with high-precision, high-quality Shenzhen circuit board, gold-plated circuit board color quality assurance reasons, and reasonable price . Surface of the circuit board processing there are many, Shen gold, silver, gold etc. craft gold-plate and gold plate is now commonly used in circuit board manufacturing processes. With a more integrated IC, IC foot the more dense. The vertical HASL process is difficult to become thin pads blow smooth, which gives the SMT placement brings the difficulty; another HASL's stand (shelf life) is very short. The gold plate just to solve these problems. The method of reduction reaction by chemical oxidation layer coating, generally thicker, a chemical nickel gold layer deposition method can achieve a thicker layer of gold, usually called gold-plating of gold in the 1840 Elkingtons invention the cyanide gold-plated patent, creating a gold-plated technology precedent. Gold-plated technology not only effectively use features six gilded gold circuit board, and the key parts of the gold used is needed is a festival gold new technology, high economic efficiency, there is a wide range of practical value; in decorative plating and electronics widely used in industry; four gold-plated circuit board | Shenzhen gold-plated circuit board | Newell record (view) provided by the Department of Shenzhen-Electronic Technology Co., Ltd. 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.
