Sensors Stimulus

MEMS/Sensors Stimulus Units

SPEA handlers are complemented by the widest range of test units, so to combine in a single equipment all the elements of handling, contacting, and complete testing of MEMS and other devices. SPEA test units can include physical MEMS stimulus, contacting unit, and the required test resources.

Everything is designed and manufactured directly by SPEA for the integrated working, providing best technical performance, cost optimization, one-shot factory integration.

The cost of test is greatly reduced, thanks to the high throughput, lower investment, short application development time and rapid accomodation of different applications.
