Performance Test of Spring Loaded Pins
Contact resistance testing: measured under standard load compression ≤50mΩ, stability evaluated through 10,000 cycles of testing and data curve attached.
Elastic curve calibration: Provide a complete force response curve within the range of 1.00mm to compression limit, supporting ± 5gf tolerance verification.
Travel stability test: Conduct 10,000 reciprocating strokes at the rated maximum compression displacement without any jamming or structural failure records.
Coating wear resistance test: After completing the spring loaded pins according to ASTM B571 standard, at least 80% of the effective contact area should be free of substrate exposure.
End welding reliability test: The tail of the solder cup is welded with lead-free tin material for tensile testing, with a minimum holding force of >10N.
High frequency mating life test: For rapid contact, the contact impedance drift should be ≤5% after ≥20 times/minute and 10,000 times of plugging and unplugging.
Spring loaded pins salt spray test: Conduct a 48 hour salt spray test according to IEC 60068-2-11, and the contact resistance change rate after the test is less than 10%.
Vibration and impact testing: Complies with Method 204D (vibration) and Method 213B (impact) requirements of MIL-STD-202G standard.
Continuity detection of conductivity: Spring loaded pins achieve stable conductivity throughout the entire compression stroke, with a response time of ≤10μs and no interruption points.
Hot cycle test: Alternating 100 cycles in an environment from -40℃ to+85℃, the contact performance of spring loaded pins does not degrade.
Dimensional stability and repeatability verification: high-precision laser measurement of the total length, tolerance range, compression displacement, etc. of spring loaded pins. Attached is a batch deviation chart.
