Inductor built-in substrate with magnetic resin body
A recently granted patent (Publication Number: US11887767B2) discloses an innovative inductor built-in substrate designed to enhance performance and efficiency. The invention comprises a core substrate with an opening and a first through hole, first and second copper foils, a magnetic resin body filled in the opening of the core substrate, and a second plating film. The magnetic resin body is in direct contact with the inner wall of the core substrate, and the second plating film extends on the magnetic resin body and copper foils, with varying thicknesses for optimal functionality. The unique design aims to improve the overall performance of the inductor built-in substrate.
Furthermore, the patent also details a method for manufacturing the inductor built-in substrate, involving the formation of the core substrate, filling of the magnetic resin, and the application of plating films. The method includes steps such as filling a filler in the through holes, forming electroless and electrolytic plating films, and creating a circuit pattern on the core substrate. By incorporating an iron filler in the magnetic resin body, the manufacturing process aims to enhance the magnetic properties of the substrate. Overall, the patented technology offers a novel approach to designing and manufacturing inductor built-in substrates, with a focus on improving efficiency and performance in various applications.
