Abstract:
A cradle for a metal electrode leadless face (MELF) device is provided. The cradle can include at least one pad, such as a solder pad, to be connected to a printed circuit board (PCB) or similar board. The pad can be configured to receive a MELF device. Such a configuration can improve positioning and alignment of the MELF device and prevent or reduce movement of the MELF device prior to or during soldering. The pad can include boundaries to engage the MELF device for alignment and to prevent or reduce movement. The boundaries of the pad can include inlets, extensions, troughs, borders, and/or other features to engage the MELF device. Boards including such cradles are also provided. Further, methods of installing a MELF device on a board using a cradle are also provided.
Abstract:
A mounting structure for an electronic component and a method for mounting the electronic component are provided with a sufficient reinforcing effect for the relatively tall electronic component raised from a substrate. The mounting structure and the mounting method can easily respond to a change of the shape of the electronic component. In a mounting structure 1, a substrate 2 and an electronic component 4 raised on the substrate 2 are joined with bonding metal 3 and a reinforcing resin body 5 is bonded to the substrate 2 and the electronic component 4. The reinforcing resin body 5 includes a plurality of reinforcing resin layers 5a. The reinforcing resin layers 5a constituting the reinforcing resin body 5 are stacked in the height direction of the raised electronic component 4 along a side 4a of the electronic component 4 so as to be raised from the substrate 2.
Abstract:
A streamlined battery pack can contain at least two battery cells. A printed circuit board (PCB) of the battery pack can include a protection control module. The PCB can have castellations along its perimeter in which wires are soldered. The wires can include battery power wires and battery monitoring signal wires. The castellations are sized so that the egress wires can be soldered therein without substantially protruding from the outline of the PCB. The PCB has a surface area that is no greater than an end of the battery pack, and thereby need not exceed the outer diameter of the remainder of the battery pack. The PCB and the other battery pack components may be substantially enveloped in a polyimide material. The components of the battery pack, including the PCB can arranged, sized and configured, such that they do not create protuberances in the enveloping material.
Abstract:
An assembly provides a dual function for mounting a port connector on a circuit board and also secures a capacitor to the circuit board. The assembly includes the circuit board and a monolithic plastic frame having a flange, a snap structure, a capacitor cradle, and a socket section. The flange has a fastening structure for fastening the frame to the circuit board. The snap structure for a snap-in attachment of the port connector to the frame is arranged near an end edge of the circuit board. The capacitor cradle for holding a cylindrical capacitor is formed adjacent to the snap structure and is elevated from the circuit board by an air gap. The socket section bears socket contacts for receiving capacitor contact leads.
Abstract:
A capacitor holder comprises: a holding portion having a cylindrical inner wall surface, at least an outer peripheral portion of the inner wall surface being open, the holding portion being configured to hold a capacitor inserted through the opening into an inside of the inner wall surface; a fixed portion formed integrally with the holding portion and positioned opposite to the opening of the holding portion; a pair of fitting grooves formed at a pair of end surfaces of the fixed portion opposed to each other adjacent to the holding portion, the fitting grooves being configured to fittably engage with end edges of a printed circuit board to extend along a surface of the printed circuit board; and a proximity suppressor configured to suppress portions of the fixed portion where the fitting grooves are formed from being brought into proximity each other.
Abstract:
Provided are a nano-scale LED assembly and a method for manufacturing the same. First, a nano-scale LED device that is independently manufactured may be aligned and connected to two electrodes different from each other to solve a limitation in which a nano-scale LED device having a nano unit is coupled to two electrodes different from each other in a stand-up state. Also, since the LED device and the electrodes are disposed on the same plane, light extraction efficiency of the LED device may be improved. Furthermore, the number of nano-scale LED devices may be adjusted. Second, since the nano-scale LED device does not stand up to be three-dimensionally coupled to upper and lower electrodes, but lies to be coupled to two electrodes different from each other on the same plane, the light extraction efficiency may be very improved. Also, since a separate layer is formed on a surface of the LED device to prevent the LED device and the electrode from being electrically short-circuited, defects of the LED electrode assembly may be minimized. Also, in preparation for the occurrence of the very rare defects of the LED device, the plurality of LED devices may be connected to the electrode to maintain the original function of the nano-scale LED electrode assembly.
Abstract:
A non-planar printed circuit board has an interior surface and an exterior surface. Between the interior surface and exterior surfaces are layers of conductive and dielectric materials. Passive and active electrical components are embedded within the interior and exterior surfaces. A hollow region is defined by the interior surface of the non-planar circuit board. The non-planar printed circuit board is manufactured on a mandrel having a non-planar shape such as, for example, a cylinder or sphere so as to form a hollow, curved non-planar structure.

An electronic assembly that includes a circuit board having a substrate in which an open space is defined, and a component having a housing and a plurality of leads, the open space being large enough to receive the housing of the component at least partially.
Abstract:
A miniaturized wideband surface mount bias tee comprises a printed circuit board with a functioning first capacitor and a dummy second capacitor, and an inductor bonded atop the two capacitors. The capacitors, adhesive and solder are depositable by standard surface mount pick and place machinery. The inductor wires are bonded to one of the first capacitor bonding pads and to an inductor bonding pad. The circuit element bonding pads include portions bordering the pc board edges and are conductively connected to bonding pads on the bottom face of the pc board. Conductive thru-vias for the first capacitor bonding pads reduce parasitic inductance and extend the operating frequency range. A flat-topped insulating cap encloses the bias tee sides and top. The cap forms an air gap between the inductor and circuit elements and provides a surface for manipulating the bias tee with present-day assembly equipment.
