Abstract
A method of manufacturing magnetic core elements includes preparing a plurality of magnetic green sheets and a plurality of non-magnetic green sheets; alternately laminating the plurality of magnetic green sheets and non-magnetic green sheets directly upon one another, thereby forming a green sheet laminate; cutting the green sheet laminate into individual bodies with desired dimension; and sintering the individual bodies, thereby forming a magnetic core element with discretely distributed gaps.
Claims17
A method of manufacturing magnetic core elements, comprising:
- preparing a plurality of magnetic green sheets;
- preparing a plurality of support intermediate paste pattern embedded with an ashable pattern therein;
- alternately laminating the plurality of magnetic green sheets and the support intermediate paste pattern embedded with an ashable pattern directly upon one another, thereby forming a laminate;
- subjecting the laminate to a sintering process, wherein the ashable patterns that are interposed between the magnetic green sheets are burned out during the sintering process, thereby forming cavities in the laminate;
- filling the cavities with an adhesive;
- and
- cutting the laminate into individual bodies with desired dimension.
A method of manufacturing magnetic core elements, comprising:
- preparing a capping magnetic piece;
- preparing a plurality of lower magnetic pieces, wherein each of the lower magnetic pieces has at least two upwardly protruding legs;
- laminating the lower magnetic pieces and the capping magnetic piece, thereby forming a plurality of cavities therebetween;
- filling the cavities with an adhesive, thereby forming a laminate;
- subjecting the laminate to a curing process;
- and
- cutting the laminate into discrete core elements with desired dimension and configuration.
A method of manufacturing magnetic core elements, comprising:
- preparing a monolithic magnetic body;
- performing a diamond wire sawing process to form a plurality of trenches with high-aspect ratio and uniform trench width into a top surface of the magnetic body, wherein the trenches separate a plurality of sidewall pieces from one another, wherein the plurality of sidewall pieces are connected together by a bottom connecting portion;
- filling the trenches with an adhesive;
- and
- performing a polishing process or a cutting process to remove the bottom connecting portion, thereby forming a magnetic core element.
