Featured Products

S-Test Lab

S-TEST Lab solutions have been tailored for system level testing in development and lab environments. The core component is the S-TEST desk system. It combines a compact design with the full test interface, that enables the developer to react flexible on changing requirements already in early project phases and to also verify product performance parameters.

 

In combination with various excitation values like acceleration or pressure the system enables test labs and R&D departments to verify sensor operation under almost real-world conditions. Due to its full compatibility with the S-TEST Fab measurement hardware, tests for mass production can be already evolve during development and in turn improve time-to-market.

S-Test Fab

S-TEST Fab solutions offer manufacturers a flexible platform to develop end-of-line system level tests for different types of sensors. The simple scalability of S-TEST installations allow efficient and multi-parallel testing of a large numbers of devices and a seamless integration into fab network infrastructures.

The hard- and software supports fast adaptation to changing sensor interfaces as well as easy integration with different sensor exciter systems. With these features the S-TEST system provides a significant cost-benefit compared to classic semiconductor test systems.
