After passing through the soldering flux pool, the copper wire enters a tinning bath, penetrates out of the tinning bath, and is packed by taking up an integrated coil; however, since the copper wire is pulled, the angle of the discharged material is deviated, and once the angle is deviated, the thickness of the tin layer on the surface of the copper wire is uneven during discharging, so that a cable 'male-female surface' is formed.
