Embodiment Construction
[0098] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.
[0099] A method for authenticity identification of plastic-encapsulated devices provided by the present invention uses a machine learning algorithm to identify and in-depth study the image of the plastic-encapsulated device, and then constructs an authenticity identification model, and detects the image of the plastic-encapsulated device based on the pre-built authenticity identification model. And according to the test results to judge the authenticity of the plastic packaged device. For example, when the detection result of the authenticity identification model is "1", it can be judged that the plastic packaged device is genuine, and when th...

Description
technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for identifying authenticity of plastic-encapsulated devices. Background technique [0002] Plastic-encapsulated devices refer to semiconductor devices packaged with resin polymers. Plastic-encapsulated technology can effectively protect semiconductor devices, which has the advantages of miniaturization, high density and high reliability. However, due to the short replacement cycle of plastic-encapsulated devices and the difficulty in procurement, refurbished devices are increasingly rampant. The damage and hidden dangers of refurbished devices will seriously endanger the reliability and safety of the system using these devices. [0003] Currently, authenticity identification methods for refurbished devices mainly include methods such as external visual inspection, X-ray inspection, and internal visual inspection. Specifically, external visual inspe...
