Mr. Quality Control Explains Decapsulation
Decapsulation goes by many names, from “decap” to “de-lidding” and even “internal visual inspection.” It is a process through which the external insulating material is removed to expose the die within the device.
The die is then inspected through a high-power microscope for markings and the condition of the wafer. Through this process, we can frequently identify the authenticity of the component, the actual part number of the component, and sometimes even the functionality of the component.
When combined with electrical testing, decapsulation can be an excellent tool for identifying counterfeit and faulty product. Ask your account manager for more details.
