Temperature and humidity test

Constant Temperature and Humidity Storage Test (THS) is conducted to evaluate deterioration, performance changes, and long-term durability. In this test, samples are placed in a high-temperature, high-humidity environment for a specified period to accelerate aging and identify potential defects that could occur over years of use.

Constant Temperature and Humidity Bias Test (THB) is conducted to reproduce, in a short period of time, degradation phenomena such as metal corrosion and insulation deterioration. In this test, samples are placed in a high-temperature, high-humidity environment and energized by applying voltage to accelerate the degradation process.

Highly Accelerated Life Test (HAST) is conducted to evaluate reliability and durability by subjecting specimens to high temperature, high humidity, and high pressure stresses. This test accelerates degradation mechanisms that would normally take several years under standard environmental conditions, allowing them to be reproduced in a short period of time.

Pressure Cooker Test (PCT) is conducted to evaluate, in a short period of time, defects such as resin cracking, metal corrosion, and insulation degradation. In this test, specimens are subjected to high temperature, high humidity, and high pressure to accelerate moisture penetration into the interior of the material.

Low Temperature and Low Humidity Test is conducted to evaluate deterioration, cracking, and insulation defects caused by drying and shrinkage by maintaining the test specimen in a low-temperature, low-humidity environment. This test is used to verify reliability under cold or dry environmental conditions.
