In a significant development for the automated test equipment industry, Teradyne Inc. (NASDAQ: TER) has announced the launch of the ETS-800 D20, the latest iteration of its high-performance test systems designed for power semiconductors. This new system is set to revolutionize the testing landscape by providing a versatile, cost-effective solution tailored for both high volume and high mix/low volume device testing.

1. Meeting Evolving Market Demands

As the demand for advanced cloud computing infrastructure and electric vehicle performance accelerates, the need for precision in power semiconductor testing has never been greater. The ETS-800 D20 is engineered to meet these challenges head-on. With AI driving the evolution of cloud technologies, the requirement for highly accurate power supplies with stable voltage outputs is critical. Similarly, battery management systems in electric vehicles demand a level of accuracy that directly influences the vehicle's performance and range.

The ETS-800 platform’s unique ability to deliver the required current rapidly while measuring ultra-low resistance positions it as a leader in the industry. This capability not only reduces losses but also minimizes heat generation—an essential factor in both data centers and electric vehicles.

2. Key Features of the ETS-800 D20

Dominic Viens, Vice President and General Manager of the Power Test division at Teradyne, expressed enthusiasm about the new system, stating, “We are thrilled to introduce the Teradyne ETS-800 D20. 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.”

Dual Sector Test Head Configuration

The ETS-800 D20 boasts a dual sector test head system that provides a flexible platform for all types of test insertions and package types. Customers can configure the system to operate at low density, utilizing up to two instruments for low volume testing, or at high density, enabling simultaneous testing of up to eight sites for high volume applications.

Advantages of the ETS-800 Platform

The Teradyne ETS-800 platform is designed with several key benefits:

  • Flexibility: The platform allows users to select the ETS-800 system that best fits their specific testing requirements, accommodating both high volume and low volume/high mix applications.
  • Extensibility: Users can transition seamlessly between platforms, making use of the same tests, instruments, docking, and software across all ETS-800 systems, which maximizes capital investment and optimizes factory floor space.
  • High Performance: The ETS-800 D20 delivers a higher site count and faster test times due to its enhanced channel density.
  • Dynamic Range: The system provides the widest dynamic range, ensuring comprehensive test coverage for precision power and analog devices.

3. The Future of Power Semiconductors

With the increasing proliferation of electric vehicles and the growing power demands of data centers, the role of power semiconductors in controlling and converting power efficiently is becoming increasingly vital. The ETS-800 D20 equips customers with the necessary channel density to meet the complexities of today’s devices, facilitating higher levels of parallelism and faster testing times. This, in turn, helps clients improve their time to revenue.

4. Learn More at SEMICON West

For those interested in exploring the capabilities of the Teradyne ETS-800 portfolio, the company invites attendees to visit its booth (#5645) at SEMICON West, taking place from October 7 – 9 in Phoenix, Arizona. Additional information about the ETS-800 platform can also be found on Teradyne's official website.

As Teradyne continues to innovate in the realm of automated test equipment and advanced robotics, the introduction of the ETS-800 D20 marks a pivotal moment for both the company and its customers, solidifying its position as a leader in the market.
