MEMS Stimulus for SPEA Pick & Place Test Handlers
SPEA handlers are complemented by the widest range of stimulus units, so to combine in a single machine all the elements of handling, contacting, and complete testing of MEMS and other devices. SPEA stimulus 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 by the high throughput, lower investment, short application development time and rapid accommodation of different applications.
