Low-temperature-cofired-ceramic (LTCC) tape structures including cofired ferromagnetic elements, drop-in components and multi-layer transformer

摘要

A ferromagnetic material (18, 20) in ink or tape form is sinterable using a same firing profile as and has approximately the same thermal shrinkage characteristics as low-temperature-cofired-ceramic (LTCC) tape, and is chemically non-reactive therewith. The ferromagnetic material (18, 20) is applied to the surface of LTCC tape sheets (12, 14, 16) to form desired elements such as cores for inductors (22).
