REL. Test Items

Wisdom Int’l Co launches world top products by severer rel. test than other companies

A. High Temperature Reverse Bias ( HTRB )
The purpose of this test is to determine the sensitivity of the product to mobile ion contamination and related failure mechanisms.

B. High Temperature Gate Bias ( HTGB )
The purpose of this test is to determine the sensitivity of the product to mobile ion contamination between gate and source and related failure mechanisms.

C. Pressure Cooker Test ( PCT )
Autoclave ( ACLV ) The purpose of this test is to evaluate the moisture resistance of non-hermetic components under pressure/temperature conditions.

D. Temperature Humidity Bias ( THBT )
The purpose of this test is to evaluate the moisture resistance of non-hermetic components. The addition of voltage bias accelerates the corrosive effect after moisture penetration has taken place with time, this is a catastrophically destructive test.

E. High Temperature Storage Life ( HTSL )
The purpose of this test is to expose time/temperature failure mechanisms and to evaluate long-term strong stability.

F. TTemperature Cycle Air-to Air ( TMCL )
The purpose of this test is to evaluate the ability of the device to withstand both exposure to extreme temperature and the transition between temperature extreme, and to exposure excessive thermal mismatch between materials.
Air to air, -65℃~150℃, 15 minutes dwell time at each temperature
