A Lot Acceptance Test (LAT) is a reduced set of Qualification tests over components or equipment, required to accept a specific manufacturing lot for its use. A LAT sequence allows customers to have complete traceability of the components they are going to use in their application, starting from the wafer used during manufacturing.

Supercapacitors also called electrochemical double layer capacitors are energy storage devices storing a high volume of electric energy in the double layer between a high surface area electrode and an electrolyte. As compared to batteries no chemical reactions should occur at the electrodes.
Electronic Components Thermal shock testing is performed to determine the ability of parts to function properly in an environment with sudden extreme changes in temperature. It is also used for accelerated testing during product evaluation and qualification process.
UL94 flammability test that are referred by number of manufacturers using plastic materials such as moulding packages? Omnexus, the material selection platform for plastic material by SpecialChem provides an overview of the test in details.
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.
Red Plague is problematic corrosion appearing on silver-plated copper conductors. An electromechanical reaction is induced between copper core and silver plating of the conductor (by means of moisture and oxygen present in the silver-copper interface). Wire affected by Red Plague is mechanically compromised, increasing the failure risk linked to severe vibration and shock conditions on space flight.
The effect of current-compensated chokes on coupled interference is used for data and signal lines. They are often the only option to avoid the interference suppression component affecting the useful signal
