Whether on your manufacturing floor or at your customer’s site, wire harnesses are vital to ensuring electrical performance across industries like automotive, aerospace, medical devices, and telecommunications. Even a minor defect, such as a weak solder joint, improper crimp, or damaged wire, can result in total system failures, costly delays, and dangerous safety issues.
At QLS, we deliver third-party wire harness inspection and repair services that help OEMs and their suppliers proactively detect and resolve these issues before they escalate. Equipped with IPC/WHMA-A-620 certification, our inspection specialists are trained to ensure that every wire harness meets your unique specifications and the most rigorous industry standards.
Prevent Failures with Certified Wire Harness Inspection
Defects in wire harnesses are a leading cause of malfunctions and product recalls. That’s why QLS thoroughly inspects and tests every single component.
Visual Inspection
We identify frayed wires, loose or incorrect crimps, missing components, poor insulation, and mismatched wire gauge-to-terminal combinations.
Continuity Testing
Our technicians confirm consistent electrical flow through all circuits, detect open or shorted connections, and ensure functional integrity under load.
Labeling & Identification
We verify that all labels, markings, and wire IDs comply with IPC/WHMA-A-620 standards and customer specs to ensure traceability and accuracy.
Defect Documentation
We generate comprehensive inspection reports with visual proof and detailed notes to support corrective actions and long-term quality tracking.
Extend the Life of Your Wire Harnesses
Replacing defective wire harnesses isn’t always necessary or cost-effective. QLS provides expert repair and rework services to restore damaged wire harnesses to functionality and compliance, helping you reduce replacement costs and get production moving again.
Crimping Corrections
We rework poorly crimped terminals to restore full electrical contact, reduce resistance, and ensure reliable signal and power transmission.
Wire & Terminal Replacements
We remove and replace damaged, misrouted, or incorrectly sized wires and connectors to meet design and safety specifications.
Soldering Adjustments
We repair or reflow weak, cold, or cracked solder joints to improve conductivity, mechanical strength, and long-term wire harness durability.
We perform rework either on-site at your location or at the QLS Wire Harness Hospital™ in North Carolina. Our dedicated facility is equipped with specialized tools and staffed by highly trained technicians to restore damaged wire harnesses to specification quickly and reliably.
