Electrical Stress Testing

electrical stress testing

Electrical stress testing exercises a product near or at its electrical limits. Two productive types of electrical stress tests are Power Cycling and Voltage Margining. Power Cycling consists of turning product power on and off at specific intervals. Voltage Margining involves varying the product's DC rails above and below nominal levels. Both tests are performed in conjunction with specific temperature cycling profiles.

Common parameters that might be tested include, but are not limited to:

  • Input Voltage
  • Input Current
  • Input Frequency
  • Input Duty Cycle
  • Power Supply Environment Testing
