一种大尺寸LTCC基板钎焊型铝硅金属外壳的设计

Design of a Large-sized LTCC Substrate Brazed Aluminum Silicon Metal Shell

本文阐述了大尺寸LTCC基板钎焊型铝硅金属外壳设计的基本要点,并通过有限元分析和试验相结合的方式,论证了设计要点的合理性。研究结果表明,合理的设计应是限定激光封焊区域的宽度和深度,同时增加铝硅外壳钎焊区域的厚度。

This article elaborates on the basic points of the design of large-sized LTCC substrate brazed aluminum silicon metal shell,and demonstrates the rationality of the design points through a combination of finite element analysis and experiments.The research results indicate that a reasonable design should limit the width and depth of the laser sealing area,while increasing the thickness of the aluminum silicon shell brazing area.
