摘要: 采用带预制焊环盖板进行电子元器件密封是高可靠密封工艺常用的方法之一。在带预制Au80Sn20焊环盖板的成本构成中,金材料的成本占据主导地位。研究了盖板镀层结构优化、焊料用量的最小化、贱金属焊环应用,并结合生产效率提升、成品率保障与材料利用率改进等方面进行论述,探索在提升密封质量与可靠性的同时降低成本的有效路径,为气密性封装器件的成本控制提供了可借鉴的方案。

Abstract: Sealing electronic components using lids with preformed solder rings is a common method in high-reliability sealing processes. In the cost structure of lids with Au80Sn20 preformed solder rings, the cost of gold constitutes the dominant cost. Research has been conducted on optimizing lid plating structures, minimizing solder usage, and applying base metal solder rings. Discussions have also been held on enhancing production efficiency, ensuring yield, and improving material utilization. Exploring effective pathways to enhance sealing quality and reliability while reducing costs provides a reference solution for cost control in hermetic packages.

Key words: lid, preformed solder ring, plating, spot welding, hermetic sealing
