| 20110109419 | Thermally Conductive Coil and Methods and Systems - Embodiments of the invention provide improved thermal conductivity within, among other things, electromagnetic coils, coil assemblies, electric motors, and lithography devices. In one embodiment, a thermally conductive coil includes at least two adjacent coil layers. The coil layers include windings of wires formed from a conductor and an insulator that electrically insulates the windings within each coil layer. In some cases the insulator of the wires is at least partially absent along an outer surface of one or both coil layers to increase the thermal conductivity between the coil layers. In some embodiments, an insulation layer is provided between the coil layers to electrically insulate the coil layers. In some cases the insulation layer has a thermal conductivity greater than the thermal conductivity of the wire insulator. | 05-12-2011 |
| 20120086538 | MANUFACTURING METHOD OF COMMON MODE FILTER AND STRUCTURE OF THE SAME - A manufacturing method of common mode filters and a structure of the same are revealed. A common mode choke layer is disposed over a composite substrate and a second magnetic material layer is coated on an upper surface of the common mode choke layer. The common mode choke layer is produced by a wafer-level electrode leading out method and having leading-out terminals on sides thereof. External electrodes are formed on sides of the common mode choke layer by partial cutting, sputtering, lithography and electroplating at wafer level and corresponding to the leading-out terminals. Thereby common mode filters produced are supported more stably. Moreover, the volume is minimized due to inductive coils and external electrodes connected by wafer level packaging. Thus the common mode filters are mass-produced, the cost is down and the defect rate is reduced. | 04-12-2012 |
