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 circuit boards, circuit boards common problem solving, quality assurance, reasonable prices. Before soldering BGA, solder circuit board process, PCB and BGA to be in 80 ℃ ~ 90 ℃, 10 to 20 hours in a thermostatic oven baking conditions, the goal is in addition to wave, different bake properly adjusted more moisture level roast temperature and time. Not opened the PCB and BGA can be directly soldered. In particular, during all of the following, circuit board process, to wear an antistatic wrist strap or gloves to avoid damage from static electricity may have caused the chip division Snyder Department of International Ltd. Shenzhen-Electronic Technology Co., Ltd. Newell Year Electronic Technologies is a professional custom single-pane, double panel, 2-40 storey density multilayer professional supplier, to provide customers with high-precision, high-quality circuit board in Shenzhen, quality assurance, reasonable prices. Welding roughly divided into preheating, insulation, reflux, cooled four intervals (different BGA rework station work to do slightly different) regardless of lead solder or lead-free solder, solder balls are melted stage recirculation zone, Guangdong circuit board technology , but different temperatures, a graph can be seen as reflux before a slow warming and heat process. Understand this basic principle, any BGA rework station can be so.
