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, gold-plated circuit board recycling to provide customers with high-precision, high-quality circuit board in Shenzhen, six gold-plated circuit boards, quality assurance, reasonable prices. As for the operating control of nickel-cylinder, in terms of temperature, different series Nickel different potions its control. Under normal circumstances, the nickel cylinder operating range 86 ± 5 ℃, and some potions control in 81 ± 5 ℃. In production, the specific set according to the results of the test plate to set the different types of system boards, there may operate at different temperatures. Operating range generally yield a system board only ± 2 ℃, individual system boards may also be less than ± 1 ℃. In the concentration control, the use of the control to regulate the Ni content of the other components, when the Ni concentration is below the set value, automatically starts tonic solution added to make up a certain amount of consumption of Ni, while the other components are based on Ni fill rata amount added simultaneously.

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, then part leakage occurs Pad bits plated gold-plated circuit board recycling phenomenon _ Newell Year (Online) _ Shenzhen gold plated circuit board is provided by the Department of Shenzhen-Electronic Technology Co., Ltd.
