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. Decorative gilt is applied first and most extensive and the most amount of depletion gilded hard multilayer circuit board applications, mostly for decorative gilt gold plating, gold plating low hardness, poor wear resistance, while a single color, reach the rich colorful color effect. According to the requirements of color, resulting in a gold alloy plating: as gold and copper, silver, gold palladium circuit board design software, gold nickel, gold, cobalt circuit board, gold chrome, gold and bismuth; effectively improve the coating's gloss and color, but also greatly enhance the hardness and wear resistance 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-density multi-storey Laminates professional providers, to provide customers with high-precision, high-quality circuit board in Shenzhen, quality assurance, reasonable prices. Palladium ions residual liquid in fact, under normal circumstances, activation brought out in the secondary countercurrent washing process can be washed. Adsorption of trace elements on the substrate, the nickel-plated cylinder enough to cause bleeding occurs. On the other hand, if you say no normal factors leading to activation of the substrate absorb large amount of residue, sulfuric acid or hydrochloric acid can not wash it off, only to adjust palladium or nickel cylinders cylinders from roots. Increase after dipping and countercurrent washing, its role is to avoid too much content in the water and affect Pd Ni cylinder.
