Inductance framework having sputtering film electrode and its production method

Abstract

This invention relates to an inductance framework with sputtered film electrodes and its production method including a framework and metallic electrode layer characterizing that said framework is madeof macromolecule polymer materials, a metallic electrode layer is pasted on the end face of the framework composed of at least one layer of sputter film, which is a laminated conductor, the frameworkis prepared by the technology of vacuum environment preparation, cleaning of the framework end face and sputter and coating.

Description

technical field [0001] The invention belongs to the technical field of basic electrical components, and in particular relates to an inductance skeleton with a sputtering film electrode and a production method thereof. Background technique [0002] Existing chip inductors are composed of ferrite or ceramic skeletons, coils, etc., and the manufacturing process is as follows: plate a metal electrode layer on the end surface of the skeleton, wind it with an enameled coil, and then weld the enameled wire head to the electrode layer. The enameled wire head is burnt off the paint skin in a high-temperature tin bath above 425°C, and welded to the metal electrode. In the prior art, metal electrodes are made by coating silver-lead-palladium slurry on the surface of ferrite and other skeletons, sintering at high temperature, and then chemically electroplating nickel, copper, silver and other metal layers on the basis of this metal layer. into. Its production process is complicated, e...

Problems solved by technology

Its production process is complicated, energy consumption is high, cost is high, and environmental pollution is serious. It is difficult to deal with pollutants in the production process, and there are elements harmful to human body left on the product. It is difficult for the product to meet the standard requirements of the international market, especially , the existing SMD inductance skeleton has the problems of limited production materials such as ferrite or ceramics, large consumption of raw materials, high energy consumption, loose combination of metal electrodes and skeleton, low corrosion resistance, and relatively low tensile strength.
