VX Instruments
Experts in High-Power Semiconductor Testing

Over the last few years, high-power semiconductors have seen a surge in demand, driven by the widespread adoption of electric vehicles, mobile phones, and various compact yet powerful electronic devices. The challenge in testing these semiconductors lies in the paradox of devices getting smaller while requiring more power, which necessitates specific testing equipment.

VX Instruments GmbH, a leading developer and producer of cutting-edge test and measurement equipment, specialises in high-power semiconductor testing solutions. Tailored for applications in quality assurance labs and production testing, its instruments play a crucial role in the semiconductor, automotive, and electronics industries.

It is a leader in the testing of wide band gap semiconductors, like SiC and GaN MOSFETs which are installed in inverters for electric motors, for example. With a presence in over 30 countries across all continents, the ISO 9001:2015 certified company has solidified its reputation as a trusted development partner with its commitment to quality.

An expert in building source measure units (SMUs), VX Instruments demonstrates skill in advanced measurement tools that possess the capability to generate short pulses, handle very high pulses, and manage high currents and voltages. This proficiency ensures the effective measurement and fulfilment of test specifications as per the requirements of its customers.

VX Instruments' advanced equipment empowers manufacturers to rise to testing challenges when dealing with delicate components like SiC- and GaN MOSFETs and meet stringent test specifications, ensuring the reliability and performance of high-power semiconductor devices. Its technology integration capabilities further enhance the precision and efficiency of testing processes, contributing to the seamless development of powerful, compact electronic devices driving the mobile and electric vehicle industries.

"Our high-power semiconductor testing systems are developed with a focus on isolated electrical measurement technology for 24/7 production operations, tailored to address the distinct requirements of clients ", says Thomas Pohl, development manager at VX Instruments.

Its highly modular test system platform is designed for optimal flexibility and user-friendliness. Every VX Instruments device is fully programmable, empowering users to customise the system to meet their needs. Its modular design enables users to operate the system efficiently without requiring extensive technical expertise, allowing them to concentrate on specific testing requirements like current measurement and control without navigating complex technical intricacies.

The platform encompasses various solutions, including a high-current platform with adjustable capabilities ranging from a few amps to three kilo amps. Additionally, there's a high-voltage platform capable of testing up to five kilovolts. For applications not requiring extreme parameters, general-purpose SMUs are available, catering to the consumer market and mid-range semiconductors like MOSFETs and IGBTs.

Incorporating multiple SMUs, VX Instruments’ comprehensive test system seamlessly integrates a full-watch trigger, offering real-time system health feedback and direct control over machinery. The setup, equipped with capabilities in robust software automation and direct integration with customer databases for enterprise resource planning, excels in 24/7 operations and monitoring.

The company's standardised software methods serve as the basis for individual system specifications and help to optimise troubleshooting for new products. The digital monitoring of measurement signals enables engineers to identify and rectify problems immediately without the need for additional equipment such as oscilloscopes and probes to recognise the variability of future technologies like SiC and GaN.

VX Instruments’ dedicated team focuses on optimising hardware applications for testing equipment. Some team members concentrate on analogue development, building devices like SMUs, digitisers, and arbitrary generators. Complementing this, its software experts seamlessly integrate the digital aspects into these devices. Another robust development team is dedicated to creating innovative devices and systems.

This multifaceted approach allows VX Instruments to excel in hardware testing, analogue development, and software integration, ensuring a comprehensive and cohesive strategy in advancing products and systems for customers.

VX Instruments has achieved remarkable growth in the last four years, propelled by its high stability, quality, precision, and the long-term endurance of its products. As it celebrates its 25th anniversary in 2023, its focus on innovation, adaptability, and customer-centric solutions positions it as a key player in the semiconductor testing market.
