Function of Threaded Pogo Pins
Plunger
Acts as contact tip with 20 shapes, providing electrical connection to mating surfaces of client’s device. Typically made of hard gold-plated alloy for low contact resistance ≤ 50 mΩ) and strong wear resistance.
Spring
Provides force to maintain consistent contact pressure. Typical force range ≥20gf, custom force ≥5gf. Working stroke ≥0.10 mm, mechanical durability ≥ 10,000 cycles), up to 1M cycles.
Barrel
Supports and guides the plunger and spring, maintaining structural integrity. Made of brass with gold/nickel plating for corrosion resistance and conductivity.
Threaded Screw
Provides mounting and fixation by male or female thread. Typically its position is on barrel inside or outside. Threaded design ensures secure and detachable installation. Common standard thread sizes M2.0–M10.0; length customized per mounting requirements.
Installation Design and Precautions of Threaded Pogo Pins
Thread pre-tightening force control: During installation, the torque should be controlled between 0.5-0.8Nm to avoid spring deformation or material cracking caused by over-tightening. Suggest using torque tools for operation to improve consistency.
Anti-vibration and anti-loosening structure: Anti-loosening glue or locking nuts should be added in high-vibration environments. Through MIL-STD-810G testing, the threads remain tight and the contact is reliable during long-term operation. The M2.5 screw can withstand vibration for ≥5,000 cycles without loosening under the action of 0.4N.m.
Through hole tolerance matching: It is recommended to install a hole diameter of thread outer diameter +0.05mm. Coaxial errors exceeding 0.10mm will significantly increase the risk of probe side loading, resulting in travel jamming or poor contact. Complies with ISO 2768-f to prevent contact instability and mechanical stress concentration caused by eccentric installation.
Current and thermal effect control: Insufficient rebound force can lead to unstable electrical contact, while excessive rebound force will increase wear or fatigue of the mating structure. It is recommended to conduct thermal simulation when using current exceeding 5A. Ensure that the interface temperature rise is below 30℃ to prevent local overheating from causing structural failure or resistance drift.
Coating wear and impedance monitoring: Thread repeated assembly ≤10 times, using ≥0.5μm nickel gold coating to prevent contact resistance from increasing. It is recommended to conduct regular low-voltage testing to maintain impedance<50mΩ.
Reliability Test of Threaded Pogo Pins:
Mechanical life cycle test:
Perform ≥10,000 insertion and extraction cycles on threaded pogo pins to evaluate their mechanical durability. Observe the changes in insertion and extraction force and the trend curve of contact resistance to monitor contact wear. The structural continuity and fatigue life performance meet the requirements of long-period connection applications.
Contact resistance stability test:
The initial contact resistance should be ≤50mΩ, and the change after 100 insertions and removals should not exceed ± 20%. Continuously monitor resistance stability through the four wire method. Reflecting the consistency of coating uniformity and spring pressure retention performance in dynamic connections.
Stability test in constant humid and hot environment:
Keep the pogo pin at 40℃ and 95%RH humidity for 96 hours. Test its electrical performance and mechanical integrity. Observe structural abnormalities caused by coating corrosion, spring fatigue, and insulation material moisture absorption and expansion.
Salt spray corrosion test:
According to ASTM B117, the threaded pogo pins were exposed to a 5% NaCl salt spray environment for 96 hours. Test corrosion resistance of pogo pin surface coating. Conduct contact resistance measurement and surface SEM inspection after testing. To evaluate the quality of metal oxidation treatment and long-term electrical performance retention.
Vibration and impact test:
Perform sine vibration testing at 10-500Hz and 30g acceleration impact testing. This simulates the physical impacts encountered in transportation, assembly, and terminal applications. Monitor whether the contact instantaneous frequency is less than 1μs to ensure signal continuity.
Thermal shock test:
Perform 100 thermal shock cycles on pogo pins between -40℃ and+85℃. Observe the changes in contact properties of materials after thermal expansion and contraction. Verify the consistency of interface connections between multiple metallic materials and the risk of low-temperature stress cracking.
Current carrying capacity test:
Continuously apply rated current of 3A or 5A and monitor the temperature rise for 1 hour, with a limit not exceeding 30K. Measure the resistance drift as an indirect indicator of the integrity of the conductive path.
Material composition analysis:
EDX and ICP-OES were used for elemental analysis of pogo pin spring and housing materials. Confirm compliance with RoHS/REACH restriction standards and avoid prohibited elements such as lead and cadmium. Simultaneously ensuring material stability and long-term environmental reliability.
Plating thickness consistency test:
Non destructive testing of Ni/Au plating thickness. Require Au layer ≥ 0.1μm, Ni layer ≥ 3.5μm, and uniformity error ≤±10%. Verify its wear resistance and contact resistance stability under long-term use.
Compression rebound performance test:
Test the rebound rate of the spring after being compressed to its maximum stroke. Require a recovery distance of ≥90% of the original and no permanent deformation. Using laser displacement sensors for sampling ensures that the mechanical recovery ability after multiple loading meets the conditions for repeated use.
