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, gold-plated circuit board sourcing and 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 multilayer professional providers, to provide customers with high-precision, high-quality circuit board in Shenzhen, quality assurance Shenzhen gold-plated circuit board, at reasonable prices. Decorative gilt is applied first and most extensive and the most amount of depletion gilded applications, mostly for decorative gilt gold plating, gold plating low hardness, poor wear resistance, while a single color, reach a variety of color effects. According to the requirements of color, resulting in a gold alloy plating: as gold and copper, silver, gold palladium, gold and gold-circuit board, gold-nickel, gold-plated circuit board technology, gold, cobalt, gold chrome, gold and bismuth; effectively improve the plating luster and color, but also greatly enhance the hardness and wear resistance of the six gold-plated circuit boards gold-plated circuit board _ _ Shenzhen Newell Year (View) - The Department of Shenzhen Electronic Technology Co., Ltd. provided by.
