EDH3101W

Standard damp heat


Semight EDH3101W standard damp heat burn-in system can be used in the long-term reliability tests of HBT and pHEMT (enhanced/depleted) devices made of different materials in high temperature and high humidity environments. The Vds/Vce power provided by the EDH3101W standard damp heat burn-in system can be provided by the secondary driver board power supply, and the Vgs/Vbe burn-in voltage can be provided by the self-made adjustable system according to the feedback control of the Ids/Ice current value. During the test, the system can be used to make the Ids/Ic current and Vds/Vce voltage of each test station constant automatically, to ensure that each test station can be automatically adjusted to the same test conditions and to adjust the current at the ds/ce terminal in real time and to monitor the voltage and current of gs/be and ds/ce terminals, thereby, the function of reliability burn-in screening can be implemented.
