Compared with the solder wire welding method, the dip soldering method has many advantages, as follows:
First of all, in terms of welding quality, as long as the part below the surface of the tin liquid is immersed, the tin will be tinned, and the tin will be tinned 360 degrees at one time. The welding quality is very reliable. There is a large contact area between the lead wire and the aluminum enameled wire on the solder joint. Compared with the terminals), the resistance is much smaller than other places in the loop.
