1. Electronic wiring harness processing and cutting: check whether the standard type of the wire is correct; whether the size meets the requirements; the cutting must be flush, the wire must not be scratched, and the wire is not dirty.


2. Stripping: Check whether the stripping port is flat, core wire, marshalling wire, etc. cannot be stripped, and the stripping scale is correct.

  3. Marshalling disposal: Is the trimming scale correct? Is the trim straight? The core wire cannot be damaged when trimming and marshalling.

  4. Stripping the inner skin: check whether the stripping port is flat; whether the stripping scale is correct; whether there is a stripped core wire or a broken copper wire; the insulator cannot fall when it is half-stripped.

  5. Set of shortened tubes: Check whether the size and type of shortened tubes are correct.

6.Prepare soldering tin: check whether the temperature of the tin furnace is correct; whether the core wire copper wire is arranged before preparing for soldering, whether there are signs of bifurcation, twists, and discounts; whether there is a copper wire bifurcation after preparing the soldering tin, The appearance of large head, uneven copper wire, and burned insulation.

  7. Soldering tin: Check whether the temperature of the electric soldering iron is correct; the insulation should not be burnt, the tin point should be lubricated, and there should be no tin tip, and false soldering or virtual soldering is not allowed.

   8. Terminal crimping: recognize whether the standards of the terminals and wires are correct; whether the crimping of the terminal is flared, skewed, whether the insulation and core wires are too long or too short.

  9. Terminal piercing: Check whether the connector and terminal type are correct; whether the terminal is damaged or deformed; whether the terminal is missing, wrongly inserted, or not pierced in place.

  10. Cable crimping: Check whether the type of connector is correct; whether the direction of the cable is correct; whether the core wire is damaged, exposed copper, or scalded; whether the crimping is in place.

  11. Blowing and shortening the tube: Is the shortening of the tube outstanding and can not burn the insulation.

12.Assembled shell: Is the shell wrong, scratched, burrs, etc., whether there are missing parts, whether the screws are unscrewed, oxidized, discolored, loose, etc., and there is no bad conformity after assembly; if the shell is there Orientation, then it must be assembled according to requirements.

  13. Labeling: Check whether the content of the label is correct, clear, and without hyphenation; whether the scale of the label is correct; whether the label is dirty or damaged; whether the orientation of the label is correct.

  14.Tie the tie: check whether the standard, color, and orientation of the tie are correct; there is no sign of cracking or looseness.

   15.Injection molding: Check whether there is dirt on the mold, whether there is material shortage, air bubbles, poor bonding, poor hardening, etc. on the molding part.

  16 plug molding: check the plug molding for damage, unevenness, lack of material, burrs, debris, flow lines, etc., and admit that the metal terminals have no defects such as deformation, damage, and copper exposure.

  17. Electrical check: check according to the check guide ticket requirements of the corresponding product.

  18. Appearance check: pay attention to all items that can be seen.
