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 of some acceleration solution may contain a reducing agent, copper sink can be adsorbed into the slot and activated palladium particles together in the production of plate surface quick start electroless copper deposition reaction. We spend a lot of time before the discussion process rather than chemical copper itself, the reason is to ensure that the chemical deposition of copper, many processing steps to be carefully implemented. Copper is a chemical copper process chemistry final result, it is precisely because of this, some unexpected results occur, often due to a number of factors beyond its control. Schedule also includes a discussion of our production process diagram 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 of heavy copper circuit board delamination you, to provide customers with high-precision, high-quality advantages of Shenzhen board Shen copper circuit board, quality assurance, reasonable prices. A printed circuit board mask hole copper thicker plating process, the process comprising the steps of:-drilled vias, etc., and has made water holes have dried electrically conductive surface of the printed circuit boards; printed circuit board Shen copper surface coated with an insulating layer circuit board stability, and dried; the coated printed circuit board insulating layer circuit board, the need to calculate the surface area of ??the plating aperture hole, multiplied to reach the hole copper plating thickness plating density and the time required to calculate the hole copper plating current density values; for hole printed circuit boards were thicker plating hole; the hole has been thickened plated printed circuit board surface roughness; for hole copper thickness has reached the required printed circuit Clean plate, into the graphic production process. This technology can increase productivity plating production lines, reducing the production of printed circuit board copper resource consumption and reduce chemical use water resources, energy resources; the advantages of easy-precision circuit board manufacturing printed circuit board copper sink | Hunan Shen copper circuit board | Newell record provided by the Department of Shenzhen-Electronic Technology Co., Ltd. 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. The company better work attitude and constantly improving innovative ideas will lead Newell invasive and you hand into the brilliant, for a better future!
