摘　　要：金系导体低温共烧陶瓷(LTCC)技术为一些用于恶劣环境中的器件提供了高可靠性。当金厚膜导体与瓷料共烧时,无机添加剂可以和LTCC瓷料反应实现附着,但是在烧结过程中可能会发生起泡和烧结收缩失配,影响金导体的导电和焊接性能。本文针对金导体中的玻璃和无机物对金导体层和LTCC瓷料反应的影响做了综合性的研究,初步确定金导体层和瓷料的最佳烧结行为,为制备具有良好烧结匹配性、表面缺陷少、有良好附着力和键合性能的金导体浆料提供了一定参考。Low temperature co-fired ceramic（LTCC） with gold conductors offers both a high system reliability and excellent performance for applications in harsh environmental conditions. When the gold metallization is co-fired with the LTCC tape, inorganic additives in the gold conductor will interact with the LTCC tape, and the reaction product, acting as a binding phase, is essential to provide adequate adhesion for the gold metallization to the substrate. However, the product may migrate to the surface of the gold conductor, adversely affecting its bond performance. The present study focused on the interaction between inorganic additives and the LTCC tape with an attempt to optimize the sintering procedure as well as to provide experimental data for preparing excellent gold conductors for LTCC applications.
