Abstract

The need for embedding the passive components into a LTCC substrate also has been increasingly focused on. In a junction between different materials, there have been two main problems such as shrinkage difference and interaction. In this study, zero-shrinkage glass infiltration technology was adopted for the junction. Two types of commercial glasses were examined for their glass transition temperatures, viscosities at high temperature and wetting angles to ceramic powders. The wetting angle was the most dominant in the infiltration behavior. 'Pb-B-Si-O'glass which has a low wetting angle was adequate for the junction for it infiltrated completely up to 28ß| into both alumina and barium titanate layers.
