Cable Assembly Testing & Quality Control
Comprehensive testing and quality control for every cable assembly and wire harness. ISO/IATF certified facilities with rigorous inspection protocols.
Standard Testing Procedures
Every cable assembly and wire harness undergoes rigorous electrical and mechanical testing to ensure quality, reliability, and compliance with specifications.
Continuity Testing
Verifies all electrical connections are complete and wired correctly. Detects open circuits, shorts, and miswired connections.
Insulation Resistance
Measures insulation quality between conductors and ground. Ensures proper isolation and prevents electrical leakage.
Hi-Pot Testing
Dielectric withstand test applies high voltage to verify insulation can handle voltage stress without breakdown.
Visual Inspection
100% visual inspection for workmanship, proper assembly, correct labeling, and physical damage.
Pull Testing
Mechanical pull tests on crimped terminals and connectors to verify proper crimp quality and retention force.
Dimensional Check
Verify cable lengths, connector positions, and overall dimensions match specifications and tolerances.

Frequently Asked Questions
What testing is included with every cable assembly?▼
100% of our cable assemblies undergo continuity testing, insulation resistance testing, and hi-pot (dielectric withstand) testing. These tests verify proper connections, insulation quality, and electrical safety before shipment.
Can you perform custom testing procedures?▼
Yes, we can implement custom testing procedures based on your specifications or industry standards. This includes mechanical stress tests, environmental testing, signal integrity tests, and more. Provide your test plan and we'll execute it.
Do you provide test reports and certifications?▼
Every shipment includes detailed test reports documenting all testing performed, pass/fail criteria, and measured values. We can also provide certificates of conformance, material certifications, and compliance documentation as needed.
What quality certifications do you hold?▼
Our facilities are ISO 9001:2015 and IATF 16949:2016 certified. We maintain strict quality management systems and can manufacture to industry-specific standards like CE, AS/NZS, and RoHS compliance.
How do you handle failed test units?▼
Failed units are quarantined, root cause analysis is performed, and corrective actions are implemented. We rework defective units when possible or replace them at no charge. Quality issues are tracked and analyzed for continuous improvement.
Can I witness testing or inspect products before shipment?▼
Absolutely! We welcome customer visits for witness testing and final inspection. You can also request video documentation of testing procedures or arrange third-party inspection services.
What is your typical defect rate?▼
Our defect rate is consistently below 0.1% thanks to rigorous testing and quality control. We track quality metrics closely and implement continuous improvement programs to maintain the highest standards.
