Plated terminations

InactiveUS6960366B2Improved termination featureEliminate and greatly simplifyResistor terminals/electrodesFinal product manufactureTermination problemEngineering
Improved termination features for multilayer electronic components are disclosed. Monolithic components are provided with plated terminations whereby the need for typical thick-film termination stripes is eliminated or greatly simplified. Such termination technology eliminates many typical termination problems and enables a higher number of terminations with finer pitch, which may be especially beneficial on smaller electronic components. The subject plated terminations are guided and anchored by exposed internal electrode tabs and additional anchor tab portions which may optionally extend to the cover layers of a multilayer component. Such anchor tabs may be positioned internally or externally relative to a chip structure to nucleate additional metallized plating material. External anchor tabs positioned on one or both of top and bottom surfaces of a monolithic structure can facilitate the formation of selective wrap-around plated terminations. The disclosed technology may be utilized with a plurality of monolithic multilayer components, including interdigitated capacitors, multilayer capacitor arrays, and integrated passive components. A variety of different plating techniques and termination materials may be employed in the formation of the subject self-determining plated terminations.

Integrated magnetics for a DC-DC converter with flexible output inductor

An integrated magnetic assembly that allows the primary and secondary windings of a transformer and a separate inductor winding to be integrated on a unitary magnetic structure is disclosed. The unitary magnetic structure includes first, second, and third legs that are physically connected and magnetically coupled. The primary and secondary windings of the transformer can be formed on the third leg of the unitary magnetic structure. Alternatively, the primary and secondary windings can be split between the first and second legs. Thus, the primary winding includes first and second primary windings disposed on the first and second legs and the secondary winding includes first and second secondary windings disposed on the first and second legs. The inductor winding may also be formed either on the third leg or it may split into first and second inductor windings and disposed on the first and second legs. In addition, one or more legs may include an energy storage component such as an air gap. This integration of the primary and secondary windings and the inductor winding on the unitary magnetic structure advantageously decouples the inductor function from the transformer function and allows the more optimal design of both the inductor and the transformer. The unitary magnetic structure may be coupled to a full bridge, a half bridge, or a push pull voltage input source to form a DC—DC converter.
