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. Gilded into hard gold plating (gold alloy) and water gold (gold) process, gold plated with soft gold bath consisting of basically the same, but more than a few hard gold tank trace metals nickel or cobalt or iron and other elements; The purpose and effect of: Guangdong gold as a precious metal gold-plated circuit board design principle, with good weldability, oxidation resistance, corrosion resistance, low contact resistance, wear resistance, and so fine features alloy; gold plating current board Citric acid is mainly gold groove bath, with its easy maintenance, easy to operate and has been widely used; water Gold content control in 1 g / l, PH value 4.5, temperature 35 degrees, Guangdong gold-plated circuit board design principles, the proportion of about 14 degrees Baume, the current density of about 1ASD; Naide International Limited Shenzhen Branch - The Department of Electronic Science and Technology Co., Ltd. - The Department of Electronic Technology Company is a professional custom single-sided, double-sided, multi-layer 2-40 board of professional providers, to provide customers with high-precision, high-quality circuit board in Shenzhen, Guangdong gold-plated circuit board design principles, quality assurance, reasonable prices. Decorative gilt is applied first and most extensive and the most amount of depletion gilded applications, mostly for decorative gilt gold plating, gold plating low hardness, poor wear resistance, while a single color, reach a variety of color effects. According to the requirements of color, resulting in a gold alloy plating: as gold and copper, gold, silver, palladium Guangdong gold gilt circuit board design principles, gold nickel, gold, cobalt, gold chrome, gold and bismuth; effectively improve the coating's gloss and color, but also greatly enhance the hardness and wear resistance of the gold-plated circuit boards gold-plated circuit boards, Guangdong gold-plated circuit boards, creating Newell Newell Shenzhen Electronic Technology Co., Ltd. provided by. Newell Shenzhen Electronic Technology Co., Ltd. (www.yipcb.com) (www.yipcb.com) strong, credible, a printed wiring board in Shenzhen, Guangdong and other industries has accumulated a large number of loyal customers.
