THB (Temperature Humidity Bias) Evaluation System

Overview of Equipment

The THB Evaluation System is a reliability test system that applies voltage at high temperature and humidity to allow automotive semiconductors, etc. to achieve high reliability under rigorous conditions compared to consumer semiconductors.
It can tolerate a device heat-generation load of up to 300 W under conditions of 85°C/85% RH.
Upon request, we can propose optimal systems for various types of static burn-in, temperature and humidity ranges, number of tests, etc.

Features and application

Achieve highly accurate temperature and humidity control over a wide range
With the use of a refrigerator system equipped with a no-stage control electronic expansion valve, highly accurate temperature and humidity control can be achieved over a wide range not only for a normal environment of 85°C and 85% RH.
Highly accurate temperature and humidity control even with high heat generation
With the use of a large air capacity sirocco fan and a chamber rack structure that ensures temperature uniformity, this system enables high accuracy testing even at device heat generation of up to 300 W. (Allowable heat of 300 W at 85°C and 85% RH)
Low noise level
The exhaust heat blower, which accounts for much of the noise generated by the chamber, is equipped with a low-noise level fan to greatly contribute to an improvement in the equipment environment.
Environmentally-friendly system
With a design focused on recycling, the use of HFC refrigerant with a zero ozone layer depletion coefficient, and a space-saving ceiling ventilation system (air cooled system), this product was designed with the environment in mind.
