Comparison between mixed flowing gas and flowers of sulphur corrosion testing

Corrosion is a major cause for failures in electronics and its importance is increasing. Therefore, corrosion testing is also getting more and more attention these days. Choosing the most suitable test method is, however, complicated because corrosion processes are...

Which factors affect the reliability of a product?

Several factors affect the reliability of a product or the reasons for its failures searched. In this post we go through some of these factors. 1. Poor design Sometimes the cause for failure may be due to poor design. The error may have occurred for example due to too...

Bathtub curve – a useful tool to understand failure rates

One particular figure is very commonly used when reliability is discussed: a bathtub curve. The bathtub curve shows the failure rate of a product as a function of time. Thus, it is a description of various failure rates for products over their lifetime. An example of...

Why it is important to consider also absolute humidity when choosing humidity test conditions

Humidity testing is one the most commonly used accelerated reliability test methods. This makes sense since high humidity level is a one of the most common reasons to cause failures. Moreover, humidity testing is relatively easy to conduct and equipment for it is...
