Abstract:
An example device includes a lithium-based battery having conductive battery contacts protruding from a surface of the battery, where a non-conductive potion of the surface of the battery separates the conductive battery contacts. The battery is a type that undergoes an expansion during charging in which the expansion of the lithium-based battery includes an outward bulging of the non-conductive portion of the battery surface. The device includes a substrate having conductive substrate contacts. The conductive battery contacts are electrically connected to the respective conductive substrate contact via a flexible electrically-conductive adhesive that physically separates the conductive battery contacts from the respective conductive substrate contacts and allows for relative movement therebetween caused by the expansion of the lithium-based battery.

Embodiments of the present invention provide an integrated module. The integrated module includes a printed circuit board PCB and a modular device, where the modular device is mounted on the PCB; a group of front pin pads is disposed at four edges of a front surface of the PCB and the front pin pads are located around a mounted position of the modular device; and a group of bottom pin pads is disposed at four edges of a bottom surface of the PCB. Positions where the front pin pads are disposed are symmetric to positions where the bottom pin pads are disposed; and network properties of the front pin pads and those of the bottom pin pads are the same.
Abstract:
The aim of the invention is to provide shielding for EMI-endangered electronic components and/or circuits (20) of electronic devices, especially for radio transmitting devices and/or radio receiving devices of telecommunication terminals for contactless telecommunication, such as cordless telephones and mobile telephones and similar, which can be constructed without using expensive manufacturing and assembly steps without any extra space requirement. The EMI-endangered electronic components and/or circuits (20) are arranged on a separate, at least double-layered printed circuit board (2) and are embodied as a printed circuit board module. Said printed circuit board and another separate, at least two-layered printed circuit board which comprises a recess (11) for the EMI-endangered electronic components and/or circuits (10) and which is embodied in the form of a base printed circuit board (1), are joined together by soldering, preferably in the region of contact areas (12, 14, 22, 23), to form a unit such that a cage (3) is formed by the recess (11) which is disposed between two metal surfaces (13, 21) being respectively connected to the shielding surfaces (12, 22) by means of continuous, highly adjacent contacts (14, 23). The cage shields the EMI-endangered electronic components and/or circuits (20) on all sides.
Abstract:
For electrically connecting a wiring formed on one surface of an insulating substrate such as an FPC to an individual electrode arranged facing the other surface of the substrate, firstly, a through hole and a notch are formed by irradiating a laser beam from above onto the FPC. Next, the FPC is arranged to be positioned such that the individual electrode, the through hole and the notch are overlapped in a plan view. Next, an electroconductive liquid droplet having a diameter greater than a width of the notch is jetted, toward an area formed with the notch, from the one surface side of the FPC. The landed electroconductive liquid droplet flows along the notch in a thickness direction of the substrate due to an action of a capillary force and reaches assuredly to the individual electrode, thereby electrically connecting the wiring and electrode arranged sandwiching the insulating substrate assuredly.
Abstract:
In a state in which a multilayer electronic component including a resin layer disposed on a mounting board side is mounted on a mounting board, even when deformation, such as deflection and strain, occurs, a stress on the multilayer electronic component is relieved by this structure. In a multilayer electronic component (1), ends (12, 13) of columnar conductors (8, 9) protrude from a main surface (14) of a resin layer (6) facing the outside. The multilayer electronic component (1) is mounted on a mounting board (2), and the ends (12, 13) of the columnar conductors (8, 9) are electrically connecting to conductive lands (26). In this case, a predetermined gap (31) is formed between the multilayer electronic component (1) and the mounting board (2).
Abstract:
A printed wiring board comprising a circuit board (6) having a conductor circuit (5) and a through-hole (60), and a junction pin (1) inserted in the through-hole. The junction pin is made of a material which does not melt at a heating temperature in joining the junction pin to a counterpart pad (81). The junction pin includes a junction top portion (11) which is greater than the aperture diameter of the through-hole and becomes a junction part with the counterpart pad, and a leg portion (12) of a size enabling insertion into the through-hole. The leg portion is inserted in the through-hole and joined with the through-hole by a conductive material such as a solder material (20). In place of the junction pin, a junction ball of a substantially spherical shape may be joined by the conductive material.
Abstract:
A new board mounted electromechanical device (103) is provided that mounts to a relay substrate (122) to form a low profile reed relay (100). The reed relay (103) is electrically connected to the electrical contacts (128) via a signal traces (130) and additional electrical traces (130) located on the same side of the relay substrate (122) which connect to the relay"s signal and shielding. Additional traces (130) on both sides of the signal traces of the reed relay (103) provide a co-planar waveguide to maintain the desired impedance of the signal path. The reed relay (103) is mounted in an inverted manner into a cut-out (134) in the main circuit board (132) so that the other portion of the need relay (103) itself is sits within the cut-out (134) in the main circuit board (132). As a result, the need relay component (103) is recessed below the surface of the main circuit board (132) resulting in an overall low profile circuit board.

The invention relates to a component arrangement in which an electrical component (5) is sunk into a recess (4) of a printed circuit board (1), said electrical component (5) being fixed to an auxiliary printed circuit board (6) which, in turn, is connected to the printed circuit board (1). By sinking the electrical component (5) into the recess (4) of the printed circuit board (4), the amount by which the component projects (U) is advantageously reduced.
