Performance Test of Spring Contact Pins
Accurate electrical performance testing: ultra-low contact resistance<50mΩ, stable signal transmission without packet loss, suitable for high-frequency and high-speed data applications.
Elastic fatigue life test: No performance degradation after continuous compression of ≥10,000 times, meeting the reliability verification requirements of high-frequency connectors.
Salt spray corrosion test: Through 96 hours of neutral salt spray test, ensure stable conductivity even in harsh industrial/marine/medical environments.
Temperature rise test @ rated current: Under 10A conditions, the temperature rise is less than 30℃, ensuring continuous high current operation without burning the PIN.
Positioning accuracy tolerance detection: End to end coaxiality is controlled within ± 0.05mm to ensure seamless alignment of precision connectors and zero errors in automatic assembly.
Surface coating thickness scanning: Gold plating ≥1.27μm, with a full inspection uniformity of 98%+, extending contact life and reducing wear rate.
Insertion and extraction force curve tracking test: The first insertion force is controlled at 20-80g, and the pull-out force rebound consistency is excellent, suitable for automated testing fixtures.
