MT-system for motor drive IGBT modules static tests

Crea built a MT-system series tester that performs all static tests on motor drive IGBT modules
  • Iges, Vgeth, Vceon, Vf, Ices, bVces, Shunt measure, Kelvin tests performed
  • Currents up to 200A and voltages up to 2kV can be switched in a single run
  • Up to 100 tests grouped in up to 30 steps all in a single run
  • Results collection, exporting and statistical analysis
  • Enhanced software speeds up data passing between User Interface and Tester Controller
  • Enhanced Testprogram editor features: the same parameters set can apply to different junctions; Testprograms can be checked and debugged.
  • Flexible Testprogram: test flow can be made dependent on partial results (Jump on Pass/Fail)
  • Classes can be defined upon test results using the Matching editor.
  • Waveform inspection

The new series hot plate jigs and the Layout Editor allow to accomodate different packages simply changing the fixture and selecting a layout file in the testprogram.
The Layout Editor allows to check and debug the layout definition too.

General Features
