Quality inspection is critical for ejector header connectors (commonly known as IDC connector types with locking mechanisms) to ensure reliable performance in electronic applications. Here's a systematic approach to quality control:
Key Inspection Areas:
Visual Inspection: Check housing for cracks/deformation, verify pin alignment, confirm ejector header locking mechanism integrity, and inspect markings.
Dimensional Verification: Measure critical dimensions including pitch specifications for 2.54mm Pitch Ejector Header, 2.0mm Pitch Ejector Header, and 1.27mm Pitch Ejector Header models using calipers, optical comparators, and pin gauges.
Mechanical Testing: Test pin retention force, measure mating/unmating force of the ejector header connector, and evaluate locking mechanism durability through repeated cycling.
Electrical Performance: Verify contact resistance (typically <50mΩ), insulation resistance (>100MΩ), and withstand voltage according to specifications.
Material Compliance: Confirm material specifications and RoHS compliance through supplier documentation or laboratory testing.
