Reflow soldering is a solder that connect SMD or SMC with PCB by meltingthe solder utilize external heat source make solder reflow and solidify the solder bycooling it (while adopting the soldering paste ).Reliable connection of variouscomponents is attainable when the temperature section of flow oven is setupsuitably.The traditional approach of experimentally analysing production defectswould be costly and virtually impossible for the temperature field model is not builthomeland inside .An alternative to t...
