One Team from R&D to Mass Production
The entire Micro Pogo lifecycle stays in one pair of hands — research, design and manufacturing iterate together from day one, so nothing is lost in handoffs between suppliers.
R&D — Simulation First
SI, mechanical and thermal simulation validate concepts before hardware is built — covering impedance, insertion loss, return loss, crosstalk, contact stress and durability. This approach helps identify potential design risks and optimize performance at an early stage.
Design — Built for Manufacture
QFD, DFMEA and DFM methodologies with full DVP/EVP validation plans turn requirements into 0.35 mm ultra-fine-pitch micro-structures — customized for AI server, semiconductor test and other demanding applications. The team that designs knows exactly how it will be made.
Manufacturing — Batch-Stable at Scale
Precision machining and crimping deliver 10+ billion units per year with batch-stable consistency. Plating, assembly and testing are fully in-house on self-developed automated lines, with SAP-integrated production management supporting process control.
