Product reliability in all environments
Does your product need to work over a range of temperatures and humidity levels? Maybe you sell a product into multiple countries or applications.
A common source of product issues result from the operating environment. A surprising number of products have only been tested on in a stable air-conditioned lab.
Electronic device characteristics can change significantly with temperature affecting measurement, performance and operation. Signal timing, amplifier gain and noise are just a few areas that can cause issues. Overheating can bring reliability and safety issues, and for fast changing environments repeated cycling between hot and cold temperatures can cause failures, from differing expansion and contraction rates causing component, solder joint and board stresses.
A good test programme can reveal any areas of weakness to be improved or give you confidence that your product is solid and reliable.
