Abstract
Disclosed are a method for fabricating an inductor with a vertical winding and an injection molding tooling thereof. The fabrication method includes: providing a conductive member that includes a connection piece, which includes a first surface and a second surface that are oppositely arranged, and a pillar on the first surface; injecting the magnetic material onto a side of the conductive member with the pillar, such that the magnetic material and the conductive member form an integrated structure; and cutting the connection piece to form the vertical winding. The injection molding tooling includes: an upper punch for stamping a magnetic material and a conductive member into an integrated structure, a molding cavity body surrounding a periphery of a pillar of the conductive member, and a lower punch for bearing a connection piece of the conductive member.
