Automated semiconductor test equipment firm Teradyne has launched the ETS-800 D20, the latest addition to its ETS-800 platform of high-performance test systems for power semiconductors.

The Teradyne ETS-800 D20 has the flexibility to scale from low to high volume as device requirements grow.

The new configuration is a dual-sector test head system that provides a flexible and efficient platform for all test insertions and package types. The system can be configured at low density for low volume testing using up to two instruments, or at high density for high volume testing using up to eight sites that can be tested in parallel, Teradyne said.

The ETS-800 D20 can transition between platforms, leveraging the same tests, instruments, docking and software across all ETS-800 systems to maximize capital investment and factory floor space.

Battery management systems in EV have a substantial impact on the vehicle’s performance and range, requiring accuracy. The Teradyne ETS-800 platform delivers the required current in the shortest duration simultaneously to measure ultra-low resistance, ensuring lower losses and less heat generation.

“This new system offers a cost-effective and flexible solution for high volume and high mix/low volume device testing for the power semiconductors enabling today’s most critical systems and applications,” said Dominic Viens, VP and General Manager of the Power Test Division at Teradyne. “Its advanced features and compatibility with existing instruments and systems [mean] the ETS-800 D20 is poised to meet the evolving needs of our customers to help them achieve their production goals.”
