Frequency 1Hz, apply 1N stroke pressure, monitor resistance drift within ± 2.5mΩ range. Verify the safety boundary of mechanical and electrical redundancy.
Lateral vibration impact assessment: Zero break under 10g peak acceleration. Simulate sine wave scanning test through a vibration table, with a frequency range of 10Hz to 2,000Hz. The peak acceleration is 10g, and the dynamic sampling voltage is monitored for each contact fluctuation. Zero contact intermittent throughout the entire process, commonly used 3 pin connectors for UAVs and high-speed motion modules.
High and low temperature impact test: No contact failure after 300 cycles from -55℃ to 125℃. The thermal shock test should be switched between -55℃ and +125℃, with more than 300 cycles. There is no abnormal fluctuation in the resistance before and after detection, and the safety of thermal expansion and contraction in extreme environments is very high.
Dustproof and anti fouling performance evaluation: Normal contact after 72 hours of exposure to ISO Class 9 dust environment. After static exposure for 72 hours under graphite powder and micro powder dust, perform insertion and electrical testing. The signal is stable without fluctuations, and the Pogo pins’ ability to resist foreign object interference meets the requirements.
Thickness and uniformity testing of electroplating layer: The gold plating thickness is controlled at 1μm ± 0.03 μm, with a cross batch error of less than 5%. Use XRF fluorescence spectroscopy to perform batch by batch sampling to ensure uniform coating in the contact area. Electroplating consistency ensures multi batch stability and avoids contact performance deviation between batches.
Insertion force testing: Insertion force <2.5N, retention force >0.6N, stroke consistency ±0.05mm. Test insertion force to adapt to automated assembly processes. No additional compressive stress will be generated on the board, and the 3 pin connectors are stably fixed in both male and female sockets.
