One of the biggest cons of COTS is the plastic package. Plastic can cause outgassing, coating nearby components in chemicals that cause corrosion. Besides, the non-hermetic sealing can also allow humidity into packages, ultimately leading to corrosion of the semiconductor inside.

Coating Thickness Verification
The thickness of metallic coatings is routinely determined by X-ray fluorescence spectrometry. This provides a basis for assessing the quality of coated materials and therefore influences decisions regarding disposition (acceptability) of the coated product as well as control of coating processes.

Silicon Carbide (SiC) is characterized by a polymorphism structure in which there are 250 different crystal forms. Initially, when Edward Goodrich Acheson patented the method of making silicon carbide in powder form in 1893, it was used for abrasive applications. With the advancement of material technology, silicon carbide has been developed in different forms

An optocoupler, also known as an optoisolator or photocoupler, is an electronic device made up of an LED emitter combined with a photodetector, separated from each other in proximity.
There are many types of photodetectors, most of which are variations on a photodiode or phototransistor.
