声学扫描技术在高可靠领域塑封器件检测中的应用
Application of Scanning Acoustic Technology in the Detection of Plastic Encapsulated Device in the High Reliability Field
摘要
Abstract
In order to improve the reliability of plastic encapsulated device in the high reliability field,it is necessary to use scanning acoustic microscopy(SAM)to detect defects such as internal delamination,void and crack in the plastic encapsulated device. The working mechanism and several main scanning modes of SAM were introduced. The characteristics and identification method of the typical defects in the plastic encapsulated device were pointed out based on comprehensive analysis of detection examples. Detection results would be of significant on the non-destructive testing(NDT)of the plastic encapsulated device by SAM.Furthermore,suggestions for improving the current detection standard of detecting plastic encapsulated device by SAM were put forward.关键词
