One of the primary mistakes can be differentiating the product's wiring harness or individual cables. However, this section focuses exclusively on "technical and qualitative errors". The most frequently occurring errors in the cable harness production are: Wrong dimensioning of the cables Wrong tool Differences between assembled cables and documentation Not maintained documentation of revisions The correction of errors on the finished cable, in the worst case already in the application, are often disproportionately costly. For this reason, it is of particular importance to ensure the required quality with proactive measures and thus minimize the potential for errors.   For the correct dimensioning of cables, the first step is to know the environmental surroundings and thus the exact requirements. Based on this, cross-sections, sheathing, protective measures, etc. can be derived. Therefore, no savings should be made at this point of cable assembly.   The use of the appropriate tool serves several purposes. Even before the actual production, the use of the right CAD software significantly reduces the potential for errors. By using software, colliding components and discrepancies can already be identified. Furthermore, many potential, mental errors are eliminated. An example of this would be the automatic calculation of additional lengths due to bending radii.   Planning alone is not enough to produce a high-quality assembled cable. Thus, it is equally important to use the right aids and tools for the respective degree of automation during production. One possible solution is a managed tool database. The database contains, for example, original pliers and crimp applicators for the corresponding contacts.   The use of aids is particularly useful for production steps that are difficult to automate. For the laying of assembled cables, the construction of laying boards or cable sieves has proven its worth.   Deviations of the finished cable from the corresponding documentation should be noticed before leaving the factory. The best option for us at Linner is the automated 100% testing of cables. In such a test, each cable is tested via a test station before shipment. After the test adapter and the test program have been created once, the test is completed easily.   With the delivery of the cable harnesses, our customers naturally receive the corresponding test protocols for the respective batch.
