Why is it important to measure how corrosive is your use or storage environment?
Corrosion is one of the most common reason for failures, and the additional expenses due to it are counted in billions. Especially, in electrical applications corrosion can very quickly destroy the functionality of devices and in worst case be a major safety risk....
Ceramics – general properties
Material selection plays a crucial role in product development. Last week we shared an infographic about metals and their basic properties. This week we deal with ceramics. This material group is less known, but ceramic materials can be vital especially in...
Metals – general properties
Material selection plays a crucial role in product development. Materials have huge effect in reliability of the product, but they also determine things like cost and weight. Additionally, certain functionalities such as electrical conductivity can only be achieved...
Intermittent Failures – User’s and Failure Analysist’s Nightmare
A few years ago, we were buying a new mobile router for my family. After the purchase, we quite soon realised that the router had some reliability problems, and it stopped working properly, when we had used it only for a very short time. The router worked okay after...
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...
Critical parameters of thermal cycling testing
Thermal cycling testing is a very widely used especially in electronics. It exposes devices and components to fluctuating temperature, which causes fatigue in the components and especially in their interconnections. For example, cracking due to fatigue is one of the...
