    • A controlled seam magnetic core lamination utilizable in an inductor structure includes a magnetic base and first and second spaced-apart magnetic sidewalls extending substantially orthogonally from the base to define a seam therebetween. The controlled seam magnetic core lamination is utilizable in an inductor structure that includes: a non-conductive lower mold; a plurality of spaced-apart controlled seam lower laminations formed in the lower mold, each magnetic lower lamination having a horizontal base and first and second spaced-apart sidewalls extending substantially vertically upward from the base to define a seam therebetween; a non-conductive isolation layer formed on the lower mold and the magnetic lower laminations; a conductive trace formed on the isolation layer; a non-conductive upper mold formed over the isolation layer and the conductive trace; and a plurality of spaced-apart controlled seam magnetic upper laminations formed in the upper mold, each magnetic upper lamination having a horizontal base and first and second spaced-apart sidewalls that extend substantially vertically upward from the base to define a seam therebetween.
    • 可用于电感器结构的受控接缝磁芯层叠体包括磁性基座和从基座基本正交地延伸的第一和第二隔开的磁性侧壁,以在其间限定接缝。 受控接缝磁芯层叠可用于电感器结构,其包括:非导电下模; 形成在下模具中的多个间隔开的受控接缝下层叠片,每个磁下层层叠件具有水平底座以及从底座基本垂直向上延伸的第一和第二间隔开的侧壁,以在其间限定接缝; 形成在下模具和磁性下层叠板上的非导电隔离层; 形成在隔离层上的导电迹线; 形成在隔离层和导电迹线上的非导电上模; 以及形成在上模具中的多个间隔开的受控接缝磁性上层叠片,每个磁性上层压板具有水平底座和第一和第二隔开的侧壁,其从基座基本上垂直向上延伸以在其间限定接缝。
