Expanding MEMS Test Capabilities in the Chinese Market

Xcerra MEMS Test Cell at SITRI for Barometric Pressure Sensors

Xcerra, with its recognized industry-leading suite of flexible and cost-effective MEMS test cell offerings, announced today that SITRI, the Shanghai Industrial µTechnology Research Institute, has added barometric pressure sensor test and calibration to its test services offering. SITRI extends its MEMS test capabilities, based on an Xcerra Test Cell solution that includes an LTX-Credence Diamond tester, a Multitest InStrip handler and the Multitest InGyro, with the InBaro test module. The flexible and modular MEMS handling system of Multitest facilitates switching form one MEMS stimulus to another using the same base handler.

Whereas the InGyro module provides physical stimulation for inertial sensors, the InBaro supports environmental applications requiring barometric pressure conditions for calibration and testing of MEMS devices. Both set-ups feature a full temperature range from -40°C to +125°C.

The test cell for barometric test enables SITRI to provide multisite, cost efficient, accurate and reliable tri-temperature test for environmental sensors. The InBaro-based system supports very fast switching between various pressure levels, making it possible to efficiently test and calibrate at multiple pressure levels within a single insertion, ensuring fast test times even for comprehensive test cases. It can be upgraded to InHumid, which adds humidity and gas test capability to the barometric component, thereby supporting highly-integrated environmental sensors.

“The Xcerra test cell approach combines the advantages of a completely pre-validated one-stop solution with the flexibility of a modular set-up,” said Gabriela Born, Xcerra Director InMEMS and IoT Products “SITRI strategically leverages this feature to reconfigure the set-up to meet the requirements of new applications.”
