Most people are familiar with the importance of humidity control. After all, nearly every home has a humidifier, a dehumidifier, or an air conditioner. Or all three.
The importance of temperature and humidity control systems reaches far beyond the realm of the home. Scientists, researchers and businesses utilize many different types of humidity control systems for a variety of purposes.
Electrical Testing
Humidity control is of paramount importance when it comes to testing electronic products and components. Often times, a temperature-humidity-bias (THB) test is performed on electrical products within a humidity control chamber. These types of systems are also referred to as environmental chambers.
The purpose of the THB test is to check for moisture induced failures within the electrical product. In order to accomplish this, the product must undergo this test, which uses a constant temperature and an elevated relative humidity. Voltage cycling is sometimes necessary in order to prevent the product from heating up.
Package Testing
Environmental chambers are also used to test the durability of packages as they undergo extreme variations...
