摘要：
A method of producing a relatively- thick film of a magnetic material on a substrate for use in microwave and millimeter wave devices is disclosed. The method includes preparing a wet paste comprising a binder material, glass frit, and a finely-grained magnetic material; applying the wet paste over a stencil, template or mask disposed on the substrate, to form a film on a surface of the substrate; drying the wet paste within an applied magnetic field, to vaporize fluid and organic compounds in the binder material and to produce a desired magnetic orientation in the magnetic film; and sintering the magnetic film. Hot pressing the magnetic film during sintering by adding weight on the film improves density.
