Generally, the main wire is welded or straight welded during the welding process. What are the wire harness welding steps?
The wire processing factory generally adopts the soldering welding method, the right hand holding the iron iron, and the left hand holding the solder wire, the operation steps are as follows:
1. Stripping: Stripping with wire stripper should pay attention to the single wire should not hurt the wire, multistranded wire and shield wire, otherwise it will affect the quality of the joint, pay attention to the wire core when peeling the multi-strand wire Spiral. The stripping length is operated according to the process data requirements.
2. Pre-welding: Pre-welding is a key step in wire bonding. When the wire is hung, it should be rotated on the side of the tin. The direction of rotation is the same as the direction of screwing. For the stranded wire, pay attention to the “wicking effect”, that is, the solder enters the insulating layer. Inside, the cord becomes hard and easily causes joint failure.
3. Heating: First heat the component leads and pads with the preheated Lotte head.
4. Wire feeding: Hold the tin wire left and right and send it to the welded part that has been heated.
5. Leaving: After the solder wire melts and flows slowly to two-thirds of the area of the pad, the solder wire and the iron head are quickly removed.
6. Solidification: After the anti-evacuation of the iron head, do not shake the components and the circuit board. The solder joint should be naturally solidified. For the components that are easily burnt, the welding can be blown to accelerate the solidification.
7. Inspection: Check the welding quality, require a moderate amount of solder joints, smooth solder joints, and firm soldering.
