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, reasonable prices. What is a gold-plated: the entire board gold. Generally refers to the [IPG] [electroless nickel gold plate], [electrolytic gold], [Gold], [] electroless nickel gold plate, with soft gold and hard gold (generally used as Goldfinger) distinction. Skin effect refers to: a high frequency alternating current gold-plated circuit boards, the current will tend to focus on the wire surface flow. Gold-plated circuit board according to the first manufacturer to calculate 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, multi-layer 2-40 Laminates professional providers, to provide customers with high-precision, high-quality circuit board in Shenzhen, quality assurance, reasonable prices. Gold-plated circuit layer stiffened reason. After copper plating, no thorough removal of the surface film, so after washing directly into the nickel-plating tank plating operations. Therefore, nickel plating layer was separated from the copper surface. Why would the micro-film it? Because copper plating solution containing a certain amount of additives such as brighteners, leveling agents, wetting agents and the like, it refers to a small amount of additive, it does not significantly change the nature of the electrolyte in the bath, but significant improvement the nature of the production of gold-plated circuit board coating, but the coating surface will be adsorbed Such additives and other organic substances, these organic materials in the copper surface through adsorption very firmly, very difficult to use a general flow of the washing water to remove gold-plated circuit boards binding, must be equipped with a dedicated processing solution is clear processing for some time, in order to achieve satisfactory surface effects. These invisible because the transparent film, the bonding strength directly affect the nickel layer and the copper surface. Gold-plated circuit board standard, Newell record (certified), Shenzhen Gold-plated circuit board is provided by the Department of Shenzhen-Electronic Technology Co., Ltd.
