IPC/WHMA-A-620 provides a shared workmanship reference for cable and wire harness assemblies. In practice, the standard helps engineering, purchasing and production teams discuss conductor preparation, crimping, soldering, routing, labeling and finished-assembly condition using a common vocabulary. A successful quality plan does not rely on a final visual check alone. Process controls such as approved tooling, crimp-height verification, pull-force checks and first-article review help prevent variation before assemblies reach final inspection. WELLXEN combines documented process controls with application-specific inspection plans so that the acceptance criteria remain connected to the customer drawing and product function.
