UltraFLEXplus
The World’s Leading Semiconductor Test Platform
The UltraFLEXplus combines new instrument and software capabilities with a revolutionary tester infrastructure that provides a step-function improvement in throughput and engineering efficiency – all while leveraging the cumulative test IP developed over the UltraFLEX’s long history.

Advantages
Fastest Time to Production
IG-XL software compatibility and the new Broadside Applications Interface enables test engineers to be more productive from the start and reduce the time to production by more than 20%.
Highest Throughput
The new UltraFLEXplus architecture increases site counts and improves parallel test efficiency, increasing overall throughput and reducing the number of test cells required by 15%-50%.
Scalable Architecture
The UltraFLEXplus can be redeployed for multiple product lines and upgraded for future product requirements, increasing reuse and extending the asset’s useful life.
