Laser joining of LTCC ceramic and polymers

The main focus of this article lies on the development of a novel joining techno logy for LTCC ceramic and polymer sub-assemblies utilizing laser radiation. Tech nical processes and the latest results are presented as well as potential future applications. The developed joining process can be divided into two steps utili zing the same laser system: a surface modification of the joining partners and a thermal process that is melting a small portion of the polymer matrix that is b eing pressed into the roughness of the ceramic surface.
