Heating Chemical Testing

HCT refers to the process of placing a chip in a chemical reagent and heating it to a certain temperature. Through the corrosive nature of the chemical reagent, the coating on the surface of the chip is peeled off to verify whether there are any scratches, coatings, re typing, or other issues on the chip surface. Usually, visual inspection is used to verify whether the excluded chip is refurbished.

Key points of detection requirements

Testing requirements:
Fully immerse electronic components in chemical reagents, heat them to a certain temperature and time, remove the components from the reagents, and immediately wipe the surface of the components with a test cotton swab. If the wiping cotton swab is black at this time, it indicates that the components are suspected of being counterfeit.
Key detection points: secondary coating, discoloration of wiping cotton swabs.
