Bringing MEMS Testing to the Next Level


Installation of first complete Xcerra turn-key test cell for MEMS in Asia



Norwood – Xcerra finalized the installation of a complete test cell for 3/6DOF inertial and navigation MEMS applications at an Asian customer. The test cell leverages proven Xcerra expertise in highly parallel test of sensor devices, delivered through the LTX-Credence and Multitest semiconductor test brands. The customer benefits from the pre-validated test cell set-up, with integrated test program and optimization support, to rapidly realize outstanding test efficiency and target yield performance.



The Xcerra MEMS test cell ideally combines the cost of test advantages of highly-parallel, high-throughput testing with the flexibility of the scalable base equipment.



The Multitest InStrip handler with the exchangeable InFlipM MEMS stimulus and interface options and high-density Mercury contactors is combined with the Diamondx tester using DPIN96 digital pins; this combination supports the fast test and calibration of 3DOF magnetometers at 204 sites in parallel on strip, as well as 2/3DOF accelerometers at 216 sites in parallel, using the Multitest InCarrier solution for wafer level package test at about 1.5x1.5 mm device size. Changing between the applications requires less than 30 minutes to swap the test interfaces, the handler conversion kit and the test program. 



Peter Cockburn, Senior Product Manager Test Cell Innovation, explains: "The project was driven by an Asian fabless customer, who searched for a highly parallel test solution at an OSAT to support the aggressive production ramp and cost of test reduction goals for his mobility MEMS applications. With the Xcerra Test Cell Solution, the fabless customer is now able to outsource his test in a highly efficient way. In addition the OSAT can fully leverage the flexibility of the Xcerra Test Cell Solution for further business opportunities."
