Quatris Electroglas Prober

The expert for electroglas prober

Modern semiconductor production demands consistent, accurate and reliable probing for high-volume, low-cost manufacturing. Chipmakers need production-ready wafer probers that get the job done, enabling productivity and yield in any test environment.

Electroglas was the first company to produce a production worthy automatic wafer prober. Electroglas’ range of 200mm and 300mm probers were the first to offer customers such breakthroughs as frictionless motion, non-contact edge sensing, and fiducial alignment to optimize manufacturing processes and achieve higher throughput.
