Polymers- general properties
Material selection plays a crucial role in product development. Lately we have shared infographics about metals and ceramics. This week we deal with polymers. Polymers are often used to replace other materials for cost and weight saving purposes. They are very...
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...
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...
How to conduct failure analysis
Failure analysis process is used when something fails, and we need to know how and why it happened. The process itself may be very complex with numerous different analysis methods and tools. However, the overall process itself is typically quite simple and does not...
Soldering in electronics
Soldering is the main technique for forming electrical interconnections. Here is a simple infographic of the main factors related to soldering process!
Unstable resistance – Why flexible electronics should be monitored in real-time during testing
Flexible electronics means applications build with flexible substrates and materials, enabling bending and stretching of the applications. Therefore products which would not be possible with traditional electronics can be accomplished. Application such as wearable and...
