Abstract

本发明公开传递模塑电感元件及其制造方法，该元件包括：采用软磁磁胶通过传递模塑形成的磁体；以及，预制的线圈组合件，包括空心线圈和连接于空心线圈两端部的电极片，该线圈组合件在传递模塑的过程中被软磁磁胶填埋而使得整个空心线圈位于磁体内部，同时，连接于空心线圈两端部的电极片至少部分暴露于磁体外部而形成端电极。该制造方法包括：将预制的空心线圈与电极片焊接形成线圈组合件并置于预制模具的型腔中；利用处于胶状的软磁磁胶进行传递模塑，以使整个空心线圈填埋于胶状的软磁磁胶中，同时空心线圈两端部的电极片至少部分暴露于软磁磁胶以外，以作为端电极；待模具中的软磁磁胶固化形成磁体后脱模，整理端电极，得到传递模塑电感元件。
