The reflow soldering of through-hole components using solder paste in a convection oven process is called intrusive soldering. The goal of the reflow process is for the solder paste to reach the eutectic temperature at which the particular solder alloy undergoes a phase change to a liquid or molten state. At this … See more Reflow soldering is a process in which a solder paste (a sticky mixture of powdered solder and flux) is used to temporarily attach one or thousands of tiny electrical components to their contact pads, after which the entire … See more The second section, thermal soak, is typically a 60 to 120 second exposure for removal of solder paste volatiles and activation of the See more The last zone is a cooling zone to gradually cool the processed board and solidify the solder joints.
