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 storey density multilayer professional supplier, to provide customers with high-precision high quality Shenzhen board, quality assurance, what is gold-plated circuit board, at reasonable prices. The most important factor affecting the activity of the nickel content of the stabilizer cylinders, commonly used stabilizer is Pb (CH3COO) 2, or thiourea, there are two simultaneous use. The role of stabilizer is selectively control chemical nickel, and an appropriate amount of stabilizer the copper surface activation can occur after a good nickel deposit and the substrate or green oil fraction not produce chemical deposition. When the stabilizer content is low, the selective chemical nickel deteriorates, PCB surface portions are slightly active nickel deposits occur, then surface alloying problem occurs. When the high content of the stabilizer, selective chemical deposition too, PCB leakage copper surface activation effect only good bit only happen copper nickel deposit, so the phenomenon appears to be leaking portion Pad bits plated Snyder International Limited Shenzhen Branch - The Department of Electronic Science and Technology Co., Ltd. - The Department of Electronic Technology Company is a professional custom single-pane, double sided, 2-40 layer plywood professional supplier, gold-plated circuit boards multilayer principle, to provide customers with high-precision, high-quality Shenzhen circuit board, quality assurance, Shenzhen gold-plated circuit board, at reasonable prices. Gilt has two functions: one is the wear and the other is corrosion-resistant. From these two effects you can know in what situation the board was gilded. That is insertion portion: and conductive rubber in contact with the place: work in electronic equipment highly corrosive environments. Businesses are trying to reduce the need gilded area, because gold is very expensive, after all! Gold-plated circuit board Which is good, Shenzhen gold-plated circuit boards, 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!
