One tester, 6 test stations

 

DOT800T is based on a multi-core architecture: the tester can be equipped with one to six independent and configurable test cores, to perform ISO test, AC test and DC test on dedicated stations, each of which with a dedicated independent controller. With a single system, you get the power and performance of six powerful testers.

Each core can be assigned to AC, DC or ISO test stations according to the specific test requirement and operation flow. The configuration is scalable and upgradeable in the field, so to adapt the tester setup to different device requirements.

The different test programs are performed in a true parallel, asynchronous mode, since each test core controller manages test resources, instrument connections, and test program execution.

The best resources for power test

 

DOT800T features a set of state-of-the-art, specialized instruments for power semiconductor test, designed to ensure performance and reliability of the new-generation wide bandgap technologies, supporting high voltages, high currents, high power, and high switching frequencies.
High voltage and current can be supplied simultaneously in testing, while great current measurement sensitivity and high-frequency built-in digitizers guarantee the best resolution and accuracy in leakage and breakdown measurements.
Local set-up memory for on-module set-up change and embedded macros to generate ramps and triggers ensures short test time.
System wide hardware synchronization between modules, and embedded alarms on high voltage and high current modules (e.g. Over temp, over current, floating, Kelvin, …) are at the basis of safe and reliable mixed mode tester operations.

Tester stray inductance <10nH 

 

Dynamic test of high-power, high-frequency devices does not only require instrumentation performances, but also a careful design of tester connection layout, sockets and contactors, to guarantee low stray inductance along the whole signal path, so as to minimize voltage overshoots during commutation. SPEA can provide the complete test solution, with contact units that are developed and manufactured by SPEA to guarantee ease of use, performance, and lowest stray inductance, for both industry-standard and custom packages, for ambient, dual-temp or tri-temperature test.
For wafer KGD and IGBT modules, SPEA also provides complete test cells incorporating robotic automatic handling, suitable to be directly integrated in the production line.
