Delta VSD Engineering and Production Testing (MIL-STD-750D method 3161

ATMPI understands the importance of good die attach in devices including power MOSFETs; therefore ATMI develops Delta VSD (DVSD) testing for the engineering and production phases in accordance with MIL-STD-750D method 3161.

ATMPI provides the necessary inputs into the test development including:
  • Thermal characterization of the part with regard to VSD vs. Temperature
  • Test development for the initial and final VSD determination
  • Test development of the appropriate heating current pulse
  • Test development of the duration of the heating pulse to ensure that the test interrogates the die to lead frame attachment
  • Scale engineering Delta VSD (DVSD) and perform true quad site testing in production (link to the QM1000™ Tester)
