Research on Nondestructive Identification Methods for the Refurbished Parts of Plastic Packaging Substrate Devices
This study proposes a non-destructive identification method for refurbished parts of plastic packaging substrates.Through technical methods such as appearance feature analysis,X-ray analysis and acoustic scanning electron microscopy analysis,non-destructive identification of refurbished plastic packaging substrate components has been achieved.Combined with relevant cases,the typical refurbishment physical characteristics of plastic encapsulated substrate devices were revealed,effectively guiding the identification direction of plastic encapsulated substrate refurbished devices.Comprehensive evaluation and risk classification were conducted for typical refurbished physical features,further strengthening risk avoidance in the application process.
