1. Wire cutting: check whether the standard type of wire is correct; Whether the standard meets the requirements.

2. Peeling: check whether the peeling opening is uniform, core wire and group wire cannot be peeled, and whether the peeling standard is correct.

3. Marshalling disposal: whether the trimming standard is correct, whether the trimming is uniform, and whether the core wire can not be damaged during trimming.

4. Peel the endothelium: check whether the peeling opening is flush; Whether the peeling standard is correct; No core wire peeling and copper wire breaking; The insulator cannot fall off when half stripping.

5. Sleeve shortening pipe: check whether the specification and model of shortening pipe are correct.

6. Prepare for soldering: check whether the temperature of the tin furnace is correct; Whether the copper wire of the core wire is well sorted before soldering, and whether it has the appearance of bifurcation, bending, discount, etc; Check whether the copper wire is bifurcated, big end, uneven, and the insulation skin is scalded after preparing for soldering.

7. Solder: check whether the temperature of electric soldering iron is correct; Do not burn the insulation layer. The solder joints shall be lubricated and free of solder joints. False or false soldering is not allowed.

8. Terminal pressure: whether the standards of terminals and wires are correct; Whether the terminal is pressed with bell mouth, tilted, and whether the insulation skin and core wire are exposed too long or too short.
