how to improve the appearance quality of the printed circuit board flux resistance has become an urgent problem to be solved in every PCB factory. Factors that affect the appearance quality of solder resistance
its melting point is much higher than that of the tin solder, which results in the reduction of the weldability of the surface of the welding pad, and the non-wetting of the welding pad and the solder climbing to the welding end of the device are easy to
