Method for forming an inductor |
摘要 |
A method for making an embedded toroidal inductor ( 118 ) includes forming in a ceramic substrate ( 100 ) a first plurality of conductive vias ( 102 ) radially spaced a first distance from a central axis ( 101 ) so as to define an inner circumference. A second plurality of conductive vias ( 104 ) is formed radially spaced a second distance about the central axis so as to define an outer circumference. A first plurality of conductive traces ( 110 ) forming an electrical connection between substantially adjacent ones of the first and second plurality of conductive vias is formed on a first surface ( 106 ) of the ceramic substrate. Further, a second plurality of conductive traces ( 110 ) forming an electrical connection between circumferentially offset ones of the first and second plurality of conductive vias is formed on a second surface of the ceramic substrate opposed from the first surface to define a three dimensional toroidal coil. |
