Wire Harness Inspection & Rework Services
Ensuring Reliable Connections and Safe Operations
Wire harnesses are critical components in heavy trucking, aerospace, telecommunications, medical devices, and other high-performance industries. A single defect—whether insufficient soldering, improper crimping, wire damage, or incorrect wire gauge—can cause electrical failures, safety hazards, and costly production delays.
The importance of wire harness and cable harness inspection cannot be overstated, as defects in wire harnesses and cable harnesses can cause malfunctions, safety hazards, or even system failures. Quality Liaison Services (QLS) provides wire harness inspection services to catch and resolve these defects before they lead to larger issues. By ensuring that wire harnesses are properly inspected and tested, manufacturers can ensure that their products meet quality and safety standards and avoid costly recalls and repairs. With a team of IPC/WHMA-A-620 Certified Inspection Specialists (CIS)—a qualification most competitors lack—QLS ensures every harness meets strict industry and customer-specific standards.
Comprehensive Wire Harness Testing Services
Our wire harness testing services cover a wide range of industries, including automotive, aerospace, telecommunications, and medical devices. We can inspect wire harnesses of various sizes, ensuring that every connection and component is thoroughly checked for any defects or issues. Each inspection follows customer-provided work instructions, ensuring thorough evaluations that align with specific production and quality requirements. Our wire harness inspection services include:
- Visual Inspection – Detects frayed wires, weak solder joints, incorrect crimps, missing components, and improper wire gauge-to-terminal pairings.
- Continuity Testing – Verifies electrical flow to prevent faulty connections.
- Labeling and Identification – Ensures compliance with IPC/WHMA-A-620 standards and customer specifications.
- Defect Documentation and Reporting – Provides a detailed record of inspection findings to support corrective actions and quality tracking.
Wire Harness Rework Services
Defective wire harnesses don’t always require full replacement. Our wire harness rework services help manufacturers salvage and restore faulty harnesses to meet specifications and maintain production schedules. We handle:
- Crimping Corrections – Fixing poorly crimped terminals for secure electrical connections.
- Wire and Terminal Replacements – Addressing damaged or incorrectly sized wires and connectors.
- Soldering Adjustments – Repairing weak or faulty solder joints to prevent connectivity failures.
