IPC/WHMA-A-620
Crimping, soldering, and wire harness assembly inspected per IPC/WHMA-A-620 acceptance criteria.
Quality Control
100% Tested Wire Harness Quality Assurance
Every wire harness and cable assembly from ENJOE goes through a comprehensive quality control process - from incoming material inspection to final shipment inspection.
QC Process
8-Step Quality Control Process
Our quality control covers every stage of the wire harness manufacturing process, ensuring each product meets your specification.
1
Incoming Material Inspection
Verify wire gauge, connector models, terminal specifications, and jacket material against BOM before production begins
2
Wire Cutting & Stripping Inspection
Check cut length tolerance, strip length precision, and wire end quality on every batch
3
Crimping Quality Control
Inspect crimp height, crimp width, bell mouth, and terminal positioning according to IPC/WHMA-A-620 standards
4
Continuity Testing
100% electrical continuity test on every wire harness to verify correct point-to-point connections
5
Insulation Testing
Insulation resistance and hi-pot testing to ensure no short circuits or dielectric breakdown
6
Pull Force Testing
Crimp pull-force testing on crimped terminals to verify mechanical strength meets specification
7
Visual Inspection
Check for correct labeling, color coding, connector orientation, tie-wrap placement, and overall workmanship
8
Final Inspection Before Shipment
Comprehensive final check including packaging, labeling, documentation, and sample retention before dispatch
