Temperature and humidity testing determines how components, subsystems and complete systems behave in severe environments that involve elevated temperatures and high or fluctuating relative humidity. The tests can be static with constant temperature and humidity, they can involve the cycling of both, they can be temperature-humidity bias tests (where the moisture is used to induce a failure in an electrical device) or some combination of all of these.
Among other things temperature/humidity tests study the effects of climatic changes on electronic components such as failures due to parameter shifts, mechanical failures (due to rapid water or frost formation), optical failures (fogging), water tightness (package) failures, material degradation (epoxy coatings, etc.) and much more. Temperature/humidity tests are a critical component of a complete qualification program. Many electrical components, while inexpensive to purchase, may be expensive to replace. For example, an LCD on an oil exploration device or a marine instrument can cause serious down time costs in a temperature/humidity related failure. Temperature and humidity combined testing extends to complete systems and finished products that extend beyond electronic components: copiers, computers, automobiles, satellites and even parachutes require temperature/humidity testing.
NTS has been performing climatic testing for over 50 years and we understand the wide breadth of temperature/humidity testing needs. Consequently our test chambers have been assembled and kept up to date to satisfy every conceivable requirement.
