FAQ
Can pogo pin be stably inserted into a 0.90mm through-hole without affecting performance?
It can be achieved. The tail can be precision machined to 0.60mm ± 0.02mm, and it has a good interference fit with a 0.90mm ± 0.05mm through-hole design. The compression force and rebound performance are within the standard range, and the stability can be tested repeatedly by plugging.
Does pogo pin support size retention after reflow soldering/wave soldering?
Support. The tail design can add limit shoulders/positioning steps to effectively prevent high-temperature displacement. The material’s thermal expansion coefficient has been verified to match the PCB. High temperature treatment does not affect the stability of tail insertion.
Can pogo pins meet a compression stroke of 0.60mm while maintaining a total length of <5.00mm?
Bidirectional compression chambers or short stroke high-K spring structures can be designed as needed. Realize compression stroke of 0.5mm~0.6mm within a total length of 5.00mm, compatible with board to board/module docking.
Does pogo pin meet high-frequency signals or high current applications?
Satisfied. The measured contact impedance is less than 50mΩ, and the rated current supports a continuous current of 1-3A. Provide high-speed signal simulation support (S parameters, TDR curves, etc.), which can be used in conjunction with shielding shells for common ground optimization.
Can pogo pin customize supporting structures (positioning parts/housing) in parallel and assist in integrated design?
Executable. Support common mode development of integrated structural components (pogo pin + plastic positioning seat/FPC pressure plate). Internally, synchronous modeling and verification of assembly tolerances can be achieved, reducing the number of docking steps and improving overall assembly efficiency.
