当前位置: Home Products Reliability Testing Equipment Discrete Device Experiment Equipment Comprehensive Burn-in (Multifunctional) Multi functional comprehensive burn-in test system (MFS2020)

Multi functional comprehensive burn-in test system(MFS2020)

The system is applicable to burn-in of various medium and small power diodes, triodes, medium and small power FETs, voltage-regulator tube, various resistors, opto-coupler, 3-end voltage regulators, and F, B, TO-92, TO-126, TO-247, TO-220, TO-3P, chip and other packaging burn-in components, and is applicable to conducting steady-state screening tests for medium and small power components and intermittent life tests for high-power components.


  • Automatically identify the switching polarity according to the inserted burn-in plate
  • The burn-in power supply of the equipment can be set to program control mode and manual mode
  • The constant current loop can be calibrated to make the current error less than (0.2%+3mA)
  • The transverse forced air cooling structure is adopted to take away the heat generated in the burn-in process,so that the temperature of the test chamber tends to be uniform
  • 8 sets of independent fan cooling control components are provided to independently control 2 test zones
