Abstract

The invention discloses a wireless charging magnetic sheet screening method which comprises the following steps: selecting and stirring ferrite powder with uniform granularity and high activity, adding TbFx and copper-tin alloy powder into a stirrer step by step for stirring, then introducing an ingredient additive, performing doping treatment and pre-sintering treatment, pressing the mixture intoa strip-type green body, and cleaning, drying, cutting and grinding the green body in sequence to obtain a magnetic core. The method is environmentally friendly and low in energy consumption; a magnetic core product is high in performance and high in reliability.

Description

technical field [0001] The invention relates to the field of processing, in particular to a screening method for wireless charging magnetic sheets. Background technique [0002] Under the current tide of electronic products such as smart phones and tablet computers, the requirements for miniaturization and patching of electronic components are becoming stronger and stronger, and power inductors are the first to bear the brunt. Moreover, the environmental protection requirements of the products are getting higher and higher. In the previous application, the patent application No. 201210097053.0 introduced a high permeability magnetic core manufacturing method, and the patent application No. 201510962086.0 introduced a ferrite The powder sintering process and the patent application No. 201510962025.4 introduce a method for preparing an E-shaped magnetic core. Although the technical solution of the above patent application can improve productivity and can be used in the manufac...
