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 quality gold-plated circuit boards Shenzhen thicker the higher the price, quality assurance, reasonable prices. With the increasing integration of 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 of standby life (shelf life) is very short. So now most of the boards are heavy with gold or gold and silver processing method of the 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 of special gold-plated circuit boards, to provide customers with high-precision, high-quality circuit board in Shenzhen, quality assurance, reasonable prices. Nickel deposition reaction seen in metal deposition while accompanied by the deposition of elemental phosphorus. And with the increase of PH value, the deposition rate of nickel is speeding up, slowing phosphorus precipitation rate, the result is P content of the nickel-phosphorus alloy is reduced. On the contrary, with the lower PH value, P content of the nickel phosphorus gold rises. Chemical nickel deposit, the phosphorus content is generally between 7 to 11 percent change. Corrosion resistance superior to nickel-phosphorus alloy electroplated nickel, its hardness is also higher than the nickel plating.
