摘要
Abstract
The thin-walling of alumina ceramic packaging shell is beneficial for improving heat dissipa-tion capacity and reducing shell weight,but there are reliability risks in practical applications,especially in harsh working conditions for example the aerospace.It is generally believed that the strength and airtight-ness of alumina are crucial to solve the reliability problem of thin-wall ceramic packaging shells.Micro-crystalline alumina ceramics are independently developed,and the bending strength and airtightness of the ceramics are tested.By using the microcrystalline alumina ceramics,a thin-wall ceramic packaging shell with overall dimension of 1.6 mm×1.2 mm and a wall thickness of 0.15 mm is prepared.It passes the re-liability verification and meets the application requirements of new electronic devices.关键词
