Applications of Spring Loaded Pogo Pins

Automated testing platform: Conduct periodic electrical connection testing on functional modules of deep groove structures. Vertical limit space for industrial control motherboards, fixtures, complex backplane interfaces, etc. Avoid traditional probes being unable to make deep contact.

Quick plug verification of electric tool module: supports contact structure testing with high stroke impact resistance. High durability substitute connectors for interfaces of high vibration modules such as hammers and drills that are repeatedly plugged and unplugged, and subjected to electrical testing.

Compensation scheme for contact point pressure of medical imaging equipment: ensuring long-term stable conductivity. Maintainability testing points for CT, X-ray, and MRI peripheral auxiliary boards. Requires a large stroke and stable elasticity to compensate for the effects of thermal expansion and contraction.

Elastic connection of BMS module terminals for new energy vehicles: deep battery slot wiring, cross shell connection or through insulated plastic parts. Has high compression ratio and arc resistance performance.

Aerospace high-frequency assembly and disassembly maintenance system: non-welded connection points for electrical connections or high seismic environments. Ground detection of airborne equipment, dynamic monitoring interface for encapsulated internal modules.

Industrial robot gripper replacement interface: high-frequency plug-in terminal block. Fast switching of signals/power from different end effectors requires high elastic contact. Traditional hard connections have high maintenance costs.

Wearable device aging testing platform: Conduct non-destructive electrical testing on deep hole shells. Verify the functionality of electrodes embedded in thick shell materials to avoid misjudgment or rework.

Charging pile module level detection interface: large tolerance compensation and stable plugging and unplugging life. Automatic tooling inspection for components with differences in size between American and European standards, compatible with different supply chain tolerances.

Transfer point of signal circuit for heavy industry equipment: design of electrical contacts for deep well bolt channels. The connection design of mining machines, presses and other components that require probes to penetrate deeply without affecting structural integrity.

Non permanent contact points of laboratory grade precision instruments: prevent micro probes from bending or insufficient contact. For internal board testing positions of spectrometers and oscilloscopes, long stroke spring loaded pogo pins are preferred to ensure consistency.

Maintenance port for rail transit signal system: deep hole elastic access design for enclosed cabin. Rapid detection of control panels inside enclosed compartments without the need to disassemble multiple structural components.

Electrical investigation of military radar systems: capable of maintaining conductivity even in non-linear connections. The module inspection port with waterproof shell and metal packaging requires spring loaded pogo pins to be insertable and maintain stable elastic contact.

FQA

Can spring loaded pogo pins be inserted into copper plated PCB through holes ≥3mm without causing board warping or soldering voids?

It can be achieved. We support the design of pin tail step matching, and the size and tolerance control of the insertion section are based on the recommended values of IPC-2222. At the same time, the tail limit structure is used to avoid stress concentration in the welding area, which has been stably applied in 1.60mm thick PCBs.

Can spring loaded pogo pins withstand repeated insertion and extraction or impact vibration without loosening or pogo pin displacement after compression installation?

The matching accuracy between barrel tail and the through-hole is controlled within the range of ±0.02mm. The pressure holding force can reach 50N, and it has passed simulated transportation, drop experiments, and 10Hz~500Hz 3-axis sweep vibration tests. No structural displacement occurs after assembly.

Will continuous power on of 3A or more during full stroke of spring loaded pogo pins cause abnormal heating or spring failure?

can’t. All current path components are made of low resistance copper alloy material and treated with ≥ 0.5μm thick gold +3μm nickel composite electroplating. Under 5A steady-state operation, the heat rise is ≤ 20℃. The selection of springs is based on the optimization of thermal fatigue curves, with no attenuation of force values after continuous power on testing for more than 100 hours.

Can multiple Spring loaded pogo pins be modularly arranged and installed to ensure pitch tolerance and end face coplanarity?

Of course I support it. It can be designed as a modular carrier array structure, with a pitch support of ≥1.00mm and a tolerance of <±0.05mm. The coplanarity of the end face is controlled by fixture reference pressing and maintained within ±0.03mm. Suitable for multi-point synchronous contact or board to board elastic connection structures.

Is there a verifiable batch consistency record and material traceability path for spring loaded pogo pins?

Yes. All spring loaded pogo pins are encoded with marked source material, machining, and assembly batch information. Support the export of batch data packages throughout the entire process (including XRF material testing reports, coating thickness reports, and compression fatigue spectra). Meets ISO 9001 and industrial grade traceability system.
