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 electroless copper circuit board proofing, as providing customers with high precision, high quality Shenzhen board, quality assurance, reasonable prices. And MLB216 --- decontamination after clearing the residual MnO2, NaOH and potassium permanganate, to ensure that the hole wall is the best condition, which can effectively avoid plating voids, poor bonding hole wall electroless copper layer and pollution subsequent processing bath and other issues; Shen copper section one: the whole plate by drilling holes in two parts ① treatment is still covered by the inner wall surface of the substrate foil ② After drilling the formation of an epoxy fiberglass Kenai Germany - The 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 electroless copper circuit board manufacturers to provide customers high-precision, high-quality circuit board in Shenzhen, quality assurance, reasonable prices. Degreasing entire hole with a surface active agent ends, respectively, even long structure hydrophobic and hydrophilic groups of the basic law, the time when the solution. Surfactant into a water-based root deliberately choose a surfactant hydrophobic group on its end just negatively charged, positively charged hydrophilic group at one end, so that when the plate member into the aqueous solution of the hydrophobic group to avoid, to the board focus electroless copper circuit board, if the board has to penetrate into the soil matrix a hydrophobic group root electroless copper circuit board copper thickness standard, to be removed at this time the plate surface a layer of surfactant distribution, it is indeed a hydrophobic base tightly adsorbed hydrophilic groups outwardly facing side of the plate positively charged water, so the board will not only clean but also with a layer of positively charged, you can start to complete the mission of the adsorption of colloidal palladium electroless copper circuit board Benefits | Newell Year | Shenzhen electroless copper circuit board by the Department of Shenzhen-Electronic Technology Limited.
