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. 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, if the board has to penetrate into the soil matrix a hydrophobic group root surface of the plate to be removed at this time at the distribution layer of a surfactant, it does a hydrophobic group firmly adsorbed water in the plate facing side with a positive Why hydrophilic groups outwardly electric circuit board copper, so the board will not only clean but also with a layer of positively charged, you can start to complete the mission of the palladium colloid adsorbed Branch Snyder Department of International Ltd. Shenzhen-Electronic Technology Co., Ltd. - The Department of Electronic Technology Company is a professional custom single-pane, double sided, 2-40 layer multilayer professional providers, to provide customers with high-precision, high-quality multi-layer circuit boards Shenzhen circuit board copper considerations, quality assurance, reasonable prices. Problems surface tension regardless of size hole printed circuit board copper should pay attention to what, anything is possible residual air bubbles, and the surface tension of the hole invasion has a significant influence. So the use of relatively high temperature operations, helping to lower the surface tension and remove air bubbles. As for concentration problems, in order to reduce consumption and the use of a slightly lower concentration, as long as the device properly designed, in fact, higher concentrations can also operate and faster. In the process, it must first hole wall invasion, later to make the syrup into the role of the circuit board copper, or air residues, the subsequent process more difficult to enter the hole, the residues can not be removed ..
