Abstract:
A low-cost device for packaging LED dies provides superior reflectivity and thermal conductivity without covering entire surfaces of an LED luminaire with an expensive reflective aluminum substrate. The LED packaging device includes a highly reflective substrate disposed in a hole in a printed circuit board. The substrate has a reflectivity greater than 97% and includes an insulating layer and a reflective layer disposed above a thicker aluminum layer. An LED die is disposed on the top surface of the substrate. The PCB has a layer of glass fiber in resin and a metal layer. The lower surface of the PCB and the bottom surface of the substrate are substantially coplanar. The metal layer of the PCB is electrically coupled to the LED die only through bond wires. Electronic circuitry is disposed on the upper surface of the PCB and is used to control light emitted from the LED die.

In a method of manufacturing an electronic component built-in substrate of the present invention, a mounted body including a first insulating layer, a stopper metal layer formed under the first insulating layer of a portion corresponding to a component mounting region and a second insulating layer formed on a lower surface of the first insulating layer and covering the stopper metal layer is prepared, and a concave portion is obtained by penetration-processing a portion of the first insulating layer, which corresponds to the component mounting region to form an opening portion, while using the stopper metal layer as a stopper. Also, the stopper metal layer in the concave portion is removed, then an electronic component is mounted on the concave portion, and then a third insulating layer is formed on the electronic component.
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.

Abstract:
A lead plate-attached coin-type battery is constituted from a combination of a coin-type battery and a positive lead plate. In the coin-type battery, a negative cap seals the aperture of a positive outer can. In a lateral view, the positive lead plate is crank-shaped, and one end thereof is attached to the outer surface of the positive outer can of the coin-type battery. A lead plate is not attached to the negative cap. One or more projections that project in the Z axis direction are provided on the negative cap. In the lead plate-attached coin-type battery, the positive lead plate and negative cap have been attached to respective conductive lands on a circuit board by a solder reflow method.
Abstract:
This invention is directed to reduce degradation, loss, and reflection of high frequency signals of a coupling circuit for an alternating current. The coupling circuit, for connecting a first circuit element to a second circuit element, comprises a die capacitor and a chip capacitor connected in parallel to each other. The die capacitor has a first electrode that faces to and is in contact with the first circuit element, and a second electrode that is wire-bonded to the second circuit element. The chip capacitor also has a first electrode that is in contact with the first circuit element and a second electrode that is in contact with the second electrode of the die capacitor. The coupling circuit may show both advantages of superior performance at high frequencies attributed to the die-capacitor and relative large capacitance attributed to the chip-capacitor.
