In high-speed signal transmission scenarios for computing chips and AI servers, the density of miniature Pogo pins keeps rising. Issues such as impedance discontinuity, signal loss and crosstalk at high frequencies can easily compromise the communication stability of the whole system.
Top-Link integrates signal integrity simulation into the full R&D workflow of Micro Pogo products, adopting a simulation-first design optimization approach. During the project phase, engineers leverage professional simulation platforms to carry out broadband electrical simulation of interconnect channels. The simulation covers six core high-speed metrics: characteristic impedance, insertion loss, return loss, near-end crosstalk (NEXT), far-end crosstalk (FEXT) and differential-to-common mode conversion (SDC). It precisely regulates channel impedance and stabilizes it within the target range of 85±5%Ω to mitigate signal reflection. Within the broadband frequency range, it controls signal transmission loss, suppresses crosstalk between channels and differential-to-common mode noise conversion, and avoids signal distortion and electromagnetic interference under high-frequency conditions.
Engineers predict potential high-frequency failure risks from simulation results, and iteratively optimize pin structure, pin array layout and shielding design to ensure the product meets stringent high-speed specifications across the target frequency band.
Different from the traditional “prototype-test-revise” iteration cycle, simulation-driven R&D greatly improves design certainty. It guarantees the signal quality of Micro Pogo pins with miniature form factors and high-density layouts, while enabling faster responses to customized requirements. Top-Link delivers reliable domestic miniature Pogo interconnect solutions for advanced chip testing and high-speed board-to-board interconnect applications.
