Bringing MEMS Testing to the Next Level

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

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 1.5×1.5 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.”

High Current meets Strip Test: Multitest launches HC Contactor for high parallel test

Multitest announces that its new high power Kelvin contactor for strip test successfully passed a long term evaluation for a high volume automotive application at an Asian manufacturing site of a global IDM. The outstanding yield and contactor pin lifespan enable extraordinary OEE (overall equipment efficiency) and a lower overall cost of test. The evaluation ran for over a year using a SO150 package for a high current automotive application requiring very high volumes. The results proved the outstanding performance of this contacting solution: >99% first pass yield and a contact pin life span of more than 1 million insertions. The Multitest High Current Strip Contactor addresses two critical requirements: high power carrying capability and the limited space in a high parallel test set up. Usually, strip contactors are based on vertical probe designs, which cannot meet the electrical and thermal requirements of high current applications. The new contactor is based on the established Multitest ecoAmp Cantilever design and deliveries superior electrical performance and temperature accuracy.

Enabling Test for High Voltage Applications

MT9510 pick and place handler for testing up to 10 kV

Rosenheim (Germany), August 2015: Multitest has shipped the first MT9510 pick and place handler for testing high voltage applications up to 10 kV (peak). A complete solution can be provided through Multitest’s Plug & Yield program which includes a Multitest high power contactor. The entire set up has been optimized to meet the challenges of cost-efficient and reliable high voltage testing.

The Multitest high voltage solution will be deployed for the automotive market (hybrid cars) andfor consumer market applications.

The Multitest MT9510,a kitable tri-temp pick and place handler, is established as the benchmark test handler in the automotive market due to its superior temperature performance in the full ambient/hot/cold range and the broad variety of additional optional features.

The high voltage set up uses a standard MT9510 base unit. All application specific requirements are covered with the design of the dedicated high voltage conversion kit. This way the greatest flexibility at the test floor, best return on investment and lowest cost of test are achieved. With its favorable cost structure the MT9510 high voltage solution also meets the targets of more cost-sensitive applications in the consumer market.
