Magnetic Permeability Test of Thin Film Materials

Film materials with a thickness of less than 1 micron are called thin film materials, and are mainly used in the fields of semiconductor functional devices and optical coatings. For the dielectric constant and magnetic permeability of thin film materials, Tonghui's TH2851 impedance analyzer cooperates with related fixtures and software to provide a complete set of solutions.

Solution Details,

Test object: film, thickness 10μm-100μm;
Test requirements: frequency 1-20MHz; permeability range 50-200
Complex permeability is calculated by measuring the impedance parameter of the magnetic material by wrapping a wire around the magnetic material and measuring the impedance at the end of the wire. TH26088 is a fixture specially designed for measuring the magnetic permeability of magnetic materials. It can be configured with a single-turn inductor, and the material is molded into a ring shape. There is no magnetic flux leakage in the single-turn inductor, and the magnetic field in the fixture is calculated strictly according to electromagnetic theory.
