Abstract

This paper describes how a thermal and mechanical stress boundary element analysis was carried out to select a mechanical device that improves the frit salvage of a cathode ray tube (CRT). The panel and funnel of a CRT are fritted at the seal edge. To reuse a CRT, the panel and funnel are separated by etching and then applying a thermal shock. This procedure is known as frit salvage. Current yield of the frit salvage success rate is about 67%, which means that 33% of the components are lost and cannot be reused. The financial burden on the company can be reduced if the salvage rate can be improved through having a better understanding of the therma
