The wire harness manufacturing process can be challenging given the manual assembly tasks it involves, and the specifications that must be met. Quality standards are very high, particularly in the heavy transportation and off road vehicle and equipment sectors, with minimal error rates allowable.
Quality inspection procedures of the wire harness manufacturing process have generally focused on circuit presence and electrical continuity. This type of inspection also functions as a verification of the presence of correct electrical connectors or components and is conducted on the wire harness assembly board. However, this type of testing does not verify the presence of non-conducting elements of a harness like TPAs, boots, clips and zip ties, or the proper assembly of multi-part electrical connectors.
