The main function of reflow soldering furnace is to melt the solder paste connecting the components and circuit boards through the heat in reflow soldering furnace, which makes the components and circuit boards fused together, Then the solder pad is cooled by reflow soldering furnace to weld the chip element and PCB pad together.

Second hand reflow soldering - the main role of reflow soldering

air or nitrogen is heated to a high enough temperature and then blown to the circuit board which has been attached with the components, so that the melted materials on both sides of the components melt and bond with the motherboard.
the advantage of this process is that the temperature is easy to control.
oxidation can also be avoided during the soldering process, The manufacturing cost is also easier to control.
reflow soldering is mainly used in SMT process.
in SMT process, the primary effect of reflow soldering is to put the PCB board with components attached into the track of reflow welder, and change the solder paste from paste to liquid through high temperature and then to solid through heating, heat preservation, welding and cooling, The reflow soldering furnace is used to weld PCB and components.
it has the functions of high production efficiency, less welding defects and stable performance.
