Identification method of counterfeit refurbished plastic packaging device

Abstract

The invention provides an identification method of a counterfeit refurbished plastic packaging device. The identification method comprises the following steps: S1, inspecting appearance physical features of the device through- microscope amplification; S2, inspecting internal physical features of the device by using an X ray; S3, inspecting internal physical features of the device by using an acoustic scanning microscope; S4, removing a packaging material of the device in a manner of combining laser unsealing and acid unsealing; S5, performing microscopic inspection on the internal physical features of the device by using a microscope; S6, performing energy spectrum analysis on a bonding lead material inside the device; S7, inspecting chip structure features by using the scanning microscope; S8, judging whether the appearance physical features, the internal physical features, the bonding lead material and the chip structure features of the device are consistent with those of an original factory device and judging whether the device is the counterfeit refurbished device if any one or more of the appearance physical features, the internal physical features, the bonding lead materialand the chip structure features are inconsistent with those of the original factory device. The identification method provided in the invention can effectively identify the counterfeit refurbished plastic packaging device and prevent or reduce the reliability risk caused by the use of the counterfeit refurbished plastic sealing device in a complete machine.

Description

Technical field [0001] The invention relates to a device reliability detection technology, in particular to a method for identifying counterfeit refurbished plastic packaging devices. Background technique [0002] At present, many military-industrial units in my country need to purchase imported plastic-packaged components through channels such as intermediaries and agents. As purchasing personnel are not very vigilant against the phenomenon of counterfeit and refurbished imported plastic-packaged components, counterfeit and refurbished imported plastic-packaged components enter the supply chain and imported due to counterfeit refurbishment Plastic-encapsulated devices have different manifestations and have different characteristics, making it difficult for testers and users to identify them, which leads to reliability risks when used in the whole machine. [0003] In order to effectively prevent or reduce this reliability risk, it is necessary to effectively identify counterfeit an...

Problems solved by technology

[0002] At present, many military industrial units in our country need to purchase imported plastic-encapsulated devices through channels such as middlemen and agents. Because purchasers are not very vigilant about the phenomenon of counterfeit and refurbished imported plastic-encapsulated devices, counterfeit and refurbished imported plastic-encapsulated devices enter the supply chain. The manifestations of plastic-encapsulated devices are different and have different characteristics, which make it difficult for testers and users to identify them, which leads to reliability risks brought by the use in the whole machine

[0003] In order to effectively prevent or reduce this reliability risk, it is necessary to effectively identify counterfeit and refurbished imported plastic-encapsulated devices. There are no standards and effective methods for identifying the physical characteristics of counterfeit and refurbished imported plastic-encapsulated devices, which brings greater difficulties to how to accurately identify counterfeit and refurbished imported plastic-encapsulated devices
