Multi-Channel Benchtop DC-HTOL


The Multi-Channel Benchtop DC Accelerated Life Test System is an integrated software and hardware platform capable of functioning as an independent 12-channel or virtual multi-channel characterization test subsystem. This flexible platform offers an unparalleled ability to simultaneously test a large number of devices over a wide array of DC bias settings and at elevated temperature ranges, and is ideal for long-duration semiconductor high-temperature operating life (HTOL) or accelerated life test (ALT) measurement.

Each device-under-test (DUT) is individually and independently controlled for DC bias stimulus. Testing at an elevated temperature, up to 300oC, is calibrated to the DUT baseplate and is precisely controlled throughout the test duration by proprietary software and hardware embedded in the platform. The system is capable of data extraction to the device channel or junction temperature if thermal-resistance is known from the baseplate to the channel/junction. The benchtop platform is compatible with Accel-RF’s AARTS LIFETEST product line and will accept any standard test fixtures utilized in a DC-AARTS reliability test system.
