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. All components on the PCB have the same temperature at the end of this zone should be, otherwise go to the reflux temperature zone because parts will produce a variety of uneven faulty welding. Usually the active temperature range is generally 120 ~ 150 ℃, if the temperature of the active region is set too high, flux (cream) activation is not enough time, the slope of the temperature curve is incremented upward slope. Although some manufacturers allow the paste activated during some of the increase in temperature, the Shenzhen circuit board technology, but the ideal temperature curve should be smooth temperature Branch Snyder Department of International Ltd. Shenzhen-Electronic Technology Co., Ltd. - The Department of Electronic We are a technology company specializing in custom single-sided, double-sided, 2-40 storey density multilayer professional supplier of printed circuit board technology, to provide high-precision, high-quality circuit board in Shenzhen, quality assurance, reasonable price . Adopting quality hot air leveling process semi-finished products, the stripping of tin-lead alloy plating quality HASL decide the merits of the level. Therefore, to be processed in accordance with strict technology requirements. To ensure the quality of stripping you'll have to do the following aspects: the process according to the provisions of the deployment of stripping solution and analyzed; this ensures safe operation, you must use the water jacket heating, mobile phone circuit board technology, especially in large quantities stripping When, to ensure the consistency and stability of temperature; stripping process will consume a lot of chemical components within the solution, it must always be supplemented in accordance with a certain amount; in the ventilation of the parts of the stripping process; by stripping clean substrate must be carefully inspection, particularly holes
