Abstract:
A laminated bus bar comprises a pair of elongated flat conductors separated by a layer of insulating material which is provided with longitudinally spaced cut-outs. Capacitors which are comprised of a flat wafer of solid dielectric material are positioned in each of the cut-outs in the layer of insulating material and the capacitor plates are electrically and mechanically connected to the conductors.
Abstract:
A method of assembling a packaged semiconductor device starts by dropping a pre-formed capacitor precursor on a surface of or within a first substrate. An integrated circuit die is dropped on either of the first substrate. If the pre-formed capacitor precursor lacks at least a first pair of vias for providing an electrical contact between capacitor plates of said chip capacitor, then at least a first pair of vias is formed in said pre-formed capacitor precursor. The first pair of vias are filled with an electrically conductive material to form the chip capacitor, wherein said filling of said vias provides an electrical contact between said first and second capacitor plates of said chip capacitor and said electrically conductive contact regions on said first substrate. A plurality of electrically conductive material layers and a plurality of dielectric layers are alternately stacked on a second substrate. The plurality of electrically conductive material layers comprise first and second patterns. The first pattern comprises at least a first pair of overlaying areas free of said electrically conductive material, and said second pattern comprises at least a second pair of overlaying areas free of said electrically conductive material. The first pair of areas overlay areas of the second pattern having said electrically conductive material and the second pair of areas overlay areas of the first pattern having said electrically conductive material. The plurality of electrically conductive material layers are electrically isolated from one another by the dielectric layers.
Abstract:
A method of assembling a packaged semiconductor device includes dropping a pre-formed capacitor precursor and an integrated circuit on a surface of a substrate. A pair of vias are formed in the pre-formed capacitor precursor if they don't already exist. The vias are filled with an electrically conductive material to form a chip capacitor. The filling of the vias provides an electrical contact between capacitor plates of the chip capacitor and electrically conductive contact regions on the substrate.
Abstract:
A surface mount circuit protection device includes a laminar PTC resistive element having first and second major surfaces and a thickness therebetween. A first electrode layer substantially coextensive the first surface is formed of a first metal material of a type adapted to be soldered to a printed circuit substrate. A second electrode layer formed at the second major surface includes structure forming or defining a weld plate. The metal weld plate has a thermal mass and thickness capable of withstanding resistance micro spot welding of a strap interconnect without significant resultant damage to the device. The device is preferably surface mounted to a printed circuit board assembly forming a battery protection circuit connected to a battery/cell by battery strap interconnects, wherein one of the battery strap interconnects is micro spot welded to the weld plate of the device.

An electronic device is presented for electrical connection between a first pad contact of an integrated circuit component and a target contact positioned substantially in a first plane of a target platform. The electronic device includes a first surface substantially parallel to the first plane and a second surface below the first surface substantially parallel to the first plane. The first surface includes a first contact region configured to connect to the first pad contact when the electronic device is connected between the first pad contact and the target contact. The second surface includes a second contact region configured to connect to the target contact when the electronic device is connected between the first pad contact and the target contact. The electronic device further includes a multitude of electrically passive elements connected between the first and second contact regions.
Abstract:
A manufacturing technique for constructing passive electronic components in vertical configurations is disclosed. Electrically passive components are constructed in a structure that is substantially perpendicular to target platform including a first plane to provide a larger electrode contact area and a smaller physical dimension. Passive components structured to be substantially perpendicular to a plane associated with a target platform can be directly connected to pad contacts of an integrated circuit or substrate or can be embedded in a package to reduce the area overhead of a passive component while improving the effectiveness of the passive components in their applications.
