The assembly process of electronic wiring harness must be carried out very carefully, because any defect in the production and assembly process will lead to the failure of the whole product, which will lead to accidents. Although manufacturers know the seriousness, they still make some common mistakes in the production and assembly of wiring harness. Below Hong Ruisheng Electronics lists six common mistakes made by wire harness manufacturers in the production and assembly of electronic wire harness.

1. Preparing wires

Preparing wires must be carefully and accurately executed, because it determines the overall efficiency and performance of components. Many manufacturers made mistakes in the first stage and chose the wrong wires, which were cut and peeled at the end.

2. Failure to follow assembly drawings

Failure to follow assembly drawings may lead to many problems when connecting wires in chassis. Wire harness manufacturers usually connect wires incorrectly, which causes failure of conductor components and the whole system. The assembly drawings must be strictly followed in order to avoid such errors.

3. Defects in crimping

The crimping process involves connecting the wiring harness to the wiring harness, which is the most critical step in the wiring harness assembly. If improperly performed, it will lead to open or short circuit. If many manufacturers do this at will, there will be a product failure.

4. incorrect welding

Improper welding is another major area where manufacturers make mistakes. Improper welding of wires and terminals can lead to thermal damage. When performing this operation, please use correct welding equipment and correct welding temperature.

5. Lack of wires and incorrect hardware

In order to meet the project schedule, some harness manufacturers may tend to overlook the wires that are critical in assembly. This may lead to faults in harness assemblies. In addition, manufacturers may use incorrect hardware, including brackets, fixtures, washers or screws, to assemble harnesses.

6. incorrect wiring

The final step in harness assembly is to tie wires with plastic straps. Sometimes the harness manufacturer will wrap them too tightly to damage the wires. On the other hand, if it is loose, it may not hold the bundle properly, so the manufacturer must ensure that the tie is fastened around the wire in the right way.
