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. 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 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 is removed, must be equipped with a dedicated processing solution must time clear process, six gold-plated circuit boards, 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. 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 plywood professional supplier, gold circuit board cost prices providing customers with high precision, high quality Shenzhen board, quality assurance, reasonable prices. Surface of the circuit board processing there are many, gold-plated circuit board details of the deal, Shen gold, silver, gold etc. craft gold-plate and gold plate is now commonly used in circuit board manufacturing processes. With a more integrated 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's stand (shelf life) is very short. The gold plate just to solve these problems. The method of reduction reaction by chemical oxidation layer coating, generally thicker, a chemical nickel gold layer deposition method can achieve a thicker layer of gold, usually called gold-plating of gold in the 1840 Elkingtons invention the cyanide gold-plated patent, Shenzhen gold-plated circuit boards, creating a gold-plated technology precedent. Gold-plated technology not only efficient use of gold properties, and the key parts needed to use gold, gold is a festival of new technology, high economic efficiency, there is a wide range of practical value; widely used in decorative plating and electronics industries; Gold-plated circuit board manufacturer in Shenzhen _ Newell Year (online consultation) _ gold-plated circuit boards Shenzhen Department Shenzhen-Electronic Technology Co., Ltd. provided by.
