Dedicated irradiators and facilities for material studies

doEEEt Media Group
February 13, 2020
Space is a harsh environment due to vacuum, UV, temperature, vibration and radiation…etc. Before landing a space vehicle, devices and materials have to be tested at ground level in order to estimate the effect of all these parameters to know about irradiators.

Constructional Analysis in Microsection Inspection

Mari Carmen López
July 23, 2019
Cross-section analysis is a very useful way of determining the construction and material composition of electronic devices. The FP device is potted in epoxy resin. After curing, the sample is sequentially grinded up to reach the plane of interest. Then, the specimen is subjected to several polishing steps to achieve a high-quality surface to be analyzed by metallographic microscopy.
Electrothermal events in crimped connectors

What does Electrothermal events in Crimped Connectors refer to?

Francisco Javier Aparicio Rebollo
February 21, 2021
Electrothermal events. Electrothermal event refers to abnormal temperature increase leading to malfunction or catastrophic fails. The high temperature reached during such event activates or initiates some of the failure mechanism explained before, such as the growth of insulation oxide layers and outgassing processes responsible for organic contamination. Besides the formation of nonconductive layers at the contact interface, high temperature can also cause to the degradation of plastic insulators and contribute to multiple short circuit conditions.
Thermoreflectance Thermal Imaging (TTI)

Thermoreflectance Thermal Imaging, understanding the use

Submicrometric-nanometric objects nowadays present in the design of integrated circuits induce singular heat transport phenomena leading to the formation of hot-spots or strong temperature gradients at specific focal points, which compromises the suitable operation and reliability of microelectronic systems and can potentially decrease the lifetime.

The Total Ionizing Dose (TID) radiation test on EEE parts involves a number of variables and processes which must be kept under control to ensure correct test execution and compliance with the used test method. From the test plan definition to the test report issue, the proper methodology needs to be put in place.
