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 Shenzhen circuit board quality, quality assurance, gold-plated circuit board protection board, the price is reasonable. What is a gold-plated: the entire board gold. Generally refers to the [IPG] [electroless nickel gold plate], [gold] gold-plated circuit board electrolysis, [Gold] gold-plated circuit boards stretch, [electroless nickel gold plate], with soft gold and hard gold (generally used as gold finger) distinction. Skin effect refers to: a high frequency alternating current will tend to focus on the wire surface flow. Gold-plated circuit board wiring according to the calculation principles, the skin depth and frequency-dependent families 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 circuit board in Shenzhen, quality assurance, reasonable prices. As the chemical deposition of nickel metal, which itself has catalytic ability. Because of its catalytic capability inferior to palladium crystals, so the initial reaction is mainly palladium during catalysis. When the deposition of nickel palladium crystal completely covered, if the activity of the nickel cylinder insufficient, chemical deposition will stop, then drain plated problem arises. Such infiltration and leakage of nickel plated cylinder serious shortage of activity generated by plating different, because the former has been deposited about 20μ 'thin nickel plated Pad bits thus drain after immersion gold appear white rough gold surface, which absolutely no chemical nickel deposition, look to blackened copper.
