New MEMS Probe Card Technologies for Challenging Wafer Tests Needs

The advent of new applications such as 5G/6G communications, automotive electronics, artificial intelligence, etc., resulting in many wafer-level tests challenges. These challenges include high-speed tests, tri-temperature tests, fine-pitch pad/pillar, high-power (low-voltage high-current), etc.

We will present some possible solutions with new generation MEMS probe card technologies to meet these challenging issues. The technological solutions include adaptive interposers, CTE matching space transformers, coaxial MEMS probes, Kelvin MEMS probes, etc. STAr’s many new advancements have enabled us to work closely with customers to develop dedicated MEMS probe cards for new test requirements while lowering COT (Cost-of-Tests) continuously.
