Gaining A Competitive Advantage by Leveraging Xcerra Test Cell Integration

Xcerra to deliver a fully integrated and validated test cell for pressure sensor test

Xcerra provide a complete test cell to a major IDM in the automotive semiconductor market. The complete test cell solution includes the tester, handler, tester interface and the sensor test module from Xcerra, and a pressure supply unit from a third party. In addition to the hardware, Xcerra will develop the test program and provide full integration and validation services.

The Xcerra test cell will combine the high-throughput capability of the Multitest InMEMS/InCarrier solution with the cost-efficient LTX-Credence Diamondx tester. The solution will also include the integration of a third party pressure supply unit. With this Xcerra solution the customer will receive a fully integrated and validated test cell for pressure sensor calibration, trim and test, providing fast time-to-volume and optimal OEE and yield.

Andreas Nagy, Senior Director, Test Cell Innovation, comments, “With the fully integrated and validated Xcerra Test Cell the customer will benefit from high operational efficiency and an accelerated time to high volume production on day one. The high throughput solution will be able to contact 90 devices in parallel resulting in a significant cost of test advantage.”

Multitest Introduces mmWave Contactor

Revolutionary interface for high frequency testing in high volume production

Multitest successfully introduced an innovative contacting solution for testing of extremely high frequency semiconductors in high volume production. The Multitest mmWave Contactor offers field proven outstanding electrical performance while maintaining best mechanical characteristics.

Multitest has developed a revolutionary hybrid contacting solution that combines traditional spring probe architecture for low frequency and power I/O’s while incorporating a cantilever solution for the peripheral high frequency transceiver I/O’s. By combining spring probe and cantilever technologies Multitest has extended the reach of volume production contactors to the extremely high frequencies ranges needed by automotive radar, WiGig, and 5G backhaul devices.

Keeping the interface from test equipment to the device as short as possible while minimizing the number of transitions is how Multitest is able to minimize the loss and maintain broadband performance from DC to 81GHz (<-10dB return loss and 4dB to 6dB insertion loss typical at 81GHz).

The mmWave contactor addresses the mechanical requirements of high volume production by incorporating high compliance, robust spring probes and materials and onsite replacement compatibility. The contactor assembly can be fully serviced onsite without incurring delays due to shipping lead times or RMA queues. The entire contacting solution is mechanically assembled and each component can be removed and replaced on site.

The mmWave contactor solution from Xcerra is a field proven solution for high volume semiconductor test that has overcome the challenge of using of metal transmission lines for extremely high frequency applications..

Jason Mroczkowski, Director RF Product Development and Marketing explains: “With the advent of production volumes of extremely high frequency semiconductors, it begs the question, ‘How will you test it?’. The experts at Multitest have considered all factors ranging from impedance discontinuities to stackup tolerances and their impact on RF performance at mmWave frequencies. Xcerra is the only supplier offering a complete test cell solution for volume production of automotive radar devices up to 81GHz. This test cell includes the tester, handler, and interface components required for a true high volume production test of mmWave devices. A critical component of this hardware is the Multitest mmWave Contactor. To date there are many lab and low volume solutions for extremely high frequency semiconductor test, but none exist for true high volume production test of mmWave devices. Until now.”

Compliant Connectors Designed to the Project Specifications

Everett Charles Technologies leverage RF simulation expertise to optimize electrical performance of custom connector solutions

Everett Charles Technologies’ (ECT) Compliant Connectors Team successfully developed a custom solution for a demanding medical application in the area of video imaging and endoscopic data. Combining decades of experience in probes with ECT’s expert capability of RF simulation, the solution fully met the mechanical, electrical and environmental specifications while keeping to the customer’s project schedule.

This customer faced a major challenge related to a connector requirement. The connector had to fit into a tightly confined area. Therefore the connector design needed to be very compact. The application was in a very dirty environment. The connector needed to be field cleanable and withstand the environmental conditions. As an added complication, the connector had to maintain a 100 Ohm impedance for proper signal transmission. Finally a life of ten thousands of insertions was required.

ECT provided a custom solution designed to the parameters including high speed signal transmission and mechanical life meeting all electrical and mechanical challenges while keeping to the project’s development time window. ECT’s capabilities of RF signal integrity simulation and validation were key for project success. Accurately predicting electrical performance of the spring probe connector as well as complete circuit performance prior to fabrication was essential to avoid multiple iterations and delays. ECT accurately modeled electrical performance and adjusted design parameters on-the-fly to ensure the prototypes met performance specifications.

Tony DeRosa, Product Manager, commented: “In addition to our off-the-shelf ‘catalog connectors’, which can be configured to customer requirements, we offer solutions fully designed to customer specifications, where standard products can’t meet the entire set of requirements. Our in-house expertise in RF simulation is a unique and valuable asset for this. With our RF simulation and validation capabilities we optimize the design prior to production. This way we ensure both: best performance and fast project completion.”
