Abstract

The frit salvage process is used to recycle cathode ray tubes at Phillips Display. This process involves creating a crack that will separate the interface cleanly between the panel and funnel components of the cathode ray tube. The current success rate of the frit salvage process is about 67%. Due to the crack propagating into the panel, 33% of the cathode ray tubes that are lost and cannot be reused. This paper describes how a thermal stress boundary element analysis was carried out to select a mechanical device that improves the frit salvage of a 27 inch cathode ray tube (CRT) by redirecting the crack to the panel funnel interface. This application is an excellent example of using the boundary element method in an industrial setting. 1 Introduction CRTs are commonly found in televisio
