Unfortunately, plagiarism testing of electronic components is often necessary. Especially in the case of microcontrollers or special chips for safety-critical applications, such as in the automotive industry, it is of great importance that no plagiarism is used.
The plagiarism check is usually carried out by a combination of measures. One possibility is to check the external marking of the chip, such as the manufacturer’s serial number or logo. Checking imprints on the chip or packaging can also help detect counterfeits.
Another way to check for plagiarism is to analyze the electrical properties of the chip. Each chip has its own specific electrical properties, which can be recorded by a variety of measurements. By comparing these measurement data with the specifications of the original manufacturer, a possible counterfeit can be identified.
There are also other imaging methods that can be used in plagiarism detection. For example, we analyze the “inner design” of the chip using computer tomography and compare it with the design specifications of the original manufacturer.
Chip counterfeit checking is an important protective mechanism to ensure the quality and safety of electronic devices. This is the only way to ensure that no counterfeit components are used in electronic devices that may be defective or even pose a safety risk.
