| Detailed Product Description: | 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 prices, to provide customers with high-precision, high-quality circuit board in Shenzhen, quality assurance, Guangdong gold-plated circuit board, at reasonable prices. Activating the role of the copper precipitated on the surface layer of palladium, nickel starting as catalytic reactions of nuclei. Its forming process was chemically Pd and Cu in the displacement reaction. From the displacement reaction, the reaction rate of Pd and Cu will become slower, when Pd and Cu completely covered (without considering the sparse hole-dip), a substitution reaction will stop, but the actual production, it is impossible to The copper surface completely unnecessary activation (the copper surface completely covered). From a cost perspective, which makes Pd consumption soared sharply. More importantly, this is likely to cause serious quality problems diffusion coating and the like. 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, eight gold-plated circuit boards, as providing customers with high precision, high quality Shenzhen board, quality assurance, reasonable prices. What is a gold-plated: the entire board gold. Generally refers to the [IPG] [board] nickel plating, gold-plated circuit board manufacturers, the [electrolytic gold], [Gold], [] electroless nickel gold plate, with soft gold and hard gold (generally used as a cheat ) distinction. Skin effect refers to: a high frequency alternating current will tend to focus on the wire surface flow. According to calculations, the skin depth and frequency related to how to select gold-plated circuit board | Guangdong gold-plated circuit board | Newell record provided by the Department of Shenzhen-Electronic Technology Co., Ltd.
