Key Points for Quality Inspection of Wire Harness Processing
When conducting wire harness quality inspections, pay attention to the following key steps: 1. Wire Cutting: Verify that the wire dimensions meet the relevant requirements and that the wire model is correct. The cut edges must be neat and smooth—avoid scratching the wires—and ensure that the wires are free from any dirt or contamination. 2. Bundling and Processing: Check whether the trimming is neat and the dimensions are accurate. During the bundling and trimming process, make sure not to nick or damage the core wires.

In harness quality inspection, pay attention to the following key steps:
1. Wire Cutting: Check whether the wire dimensions meet the relevant requirements and whether the model is correct. The cut must be neat and precise, without damaging the wire, and the wire must be free of any dirt or contamination.
2. Bundle Processing: Check whether the trimming is neat and the dimensions are correct. During bundle formation, avoid cutting into the core wire.
3. Peel the outer jacket: Check whether the peeling opening is neat and whether the peeling dimensions are correct. Be careful not to damage the stranded wires or the core wires during the peeling process.
4. Stripping the inner insulation: Check whether the stripping cut is neat, whether the stripping dimensions are correct, whether the core wire has been damaged during stripping, and whether any copper strands have been broken. During partial stripping, the insulation must not come loose.
5. Shrink tubing: Carefully check whether the model and size of the shrink tubing are correct.
6. Preparing the solder: Check whether the temperature of the soldering pot is correct. Before preparing the solder, make sure to straighten the core wires and copper strands and check for any bends, splits, or kinks.
7. Soldering: Check whether the soldering iron’s temperature is correct; do not burn the insulation jacket. The solder joints should be smooth, free of sharp solder tips, and free from cold solder joints or false soldering.
8. Terminal crimping: Check whether the specifications of the terminals and wires are correct; also check whether the terminals are tilted or have any burrs.
9. Terminal Insertion: Verify that the terminal and connector models are correct; check whether the terminals are deformed or damaged; and ensure that there is no incorrect insertion, missing insertion, or incomplete insertion of the terminals.
10. Assemble the housing: Check whether the housing has scratches, incorrect assembly, or burrs; verify that no components are missing and that screws are free from oxidation, looseness, stripped threads, or discoloration. If the housing is directional, be sure to assemble it according to the specified requirements.
