Abstract
A method for forming electronic inductors. A model of the desired shape of the inductor is first formed in wax or other soft material. It is compressed in a block of magnetically permeable material and then heated to remove the wax shape. The resultant cavity in the shape of the inductor is filled with conductive material to form an inductor within the magnetically permeable material block.
Claims12
An apparatus comprising:
- a sacrificial element to form a cavity within a block of magnetically permeable material when removed from the block of magnetically permeable material and the cavity to be filled at least in part by insertion of electrically conductive material in the cavity to form an electronically conductive element, at least two ends of said electrically conductive element being adjacent to one or more exterior surfaces of the block.
Apparatus comprising:
- a sacrificial element to form a cavity within a block of magnetically permeable material and wherein at least two ends of an electronically conductive element to be formed in the cavity remaining after removal of the sacrificial element are adjacent to one or more exterior surfaces of the block.
