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 Shenzhen Gold-plated circuit board prices, to provide customers with high-precision, high-quality circuit board in Shenzhen, the Shenzhen Gold-plated circuit board quality assurance price, the price is reasonable. 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. 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, to provide customers with high-precision high quality Shenzhen board, quality assurance, reasonable prices. Water tank into a small amount of Pd Ni-cylinder, the cylinder will not have much impact on the nickel, so do not be too concerned about the short time after the activation of water, under normal circumstances, the total time of two water control in 1 ~ 3min better . It is particularly important that the water can not be used after the activation of an ultrasonic device, otherwise, not only lead to large-scale leakage plating, and surface alloying problem persists gilded board costs, Newell Year (online consultation), gold-plated circuit board in Shenzhen by the Shenzhen Municipal Newell Electronic Technology Limited.
