A method is presented that improves reliability for the mechanical electrical connection formed between a grid array device, such as a pin grid array device (PGA) or a column grid array device (CGA), and a substrate such as a printed circuit board (PCB). Between adjacent PCB pads, the method increases a spacing pattern toward the periphery of the CGA, creating a misalignment between pads and columns. As part of the method, columns align with the pads, resulting in column tilt that increases from the center to the periphery of the CGA. An advantage of the method is that the column tilt reduces the amount of contractions and expansions of columns during thermal cycling, thereby increasing the projected life of CGA. Another advantage of the method is that it reduces shear stress, further increasing the projected life of the CGA.

An antenna carrier plate structure has a first circuit board and a second circuit board. The first circuit board has a first substrate and a conductive connector disposed in the first substrate. The conductive connector has two opposite connecting ends respectively protruding from two opposite surfaces of the first substrate. The second circuit board has a second substrate formed with a through hole, and a connecting plug is disposed in the through hole. One end of the connecting plug is formed with an engaging concave portion for engaging one end of the conductive connector of the first substrate. Therefore, each circuit board can be firmly fixed and electrically connected by engaging to form a multi-layer circuit board module, thereby avoiding joint tolerances during soldering and ensuring a correct connection of the joints.

An electronic device having a display assembly is disclosed. Several layers may combine to form the display assembly. For example, the display assembly may include a touch sensitive layer (or touch detection layer), a display layer that present visual information, and a force sensitive layer (or force detection layer). The display layer may include a bend or curve that allows a portion of the display layer to bend around the force sensitive layer. Also, the connectors (that provide electrical and mechanical connections) may be positioned at different locations of the layers. For example, the display layer may include a connector on a first edge region, and the force sensitive layer may include a connector on a second edge region that is perpendicular, or at least substantially perpendicular, to the first edge region. By positioning the connectors on perpendicular edge regions, the display assembly may reduce its footprint.

A multilayer printed circuit board includes a first dielectric layer and a second dielectric layer, each layer having a top surface and a bottom surface. The first dielectric layer is positioned above the second dielectric layer with the bottom surface of the first dielectric layer facing the top surface of the second dielectric layer. The top surface of the second dielectric layer has a conductive trace. The second dielectric layer has a through-hole that extends through the conductive trace. The multilayer printed circuit board includes an inverted pad interface structure including an inverted pad provided on the bottom surface of the first dielectric layer, a first solder layer provided on a surface of the inverted pad, a second solder layer provided on the conductive trace, and a copper wire positioned within the through-hole to provide the vertical and electrical connection with the conductive trace.

Readily manufactured structures for sealing or encapsulating devices in system-in-a-package modules, such that the modules are easily assembled, have a low-profile, and are space efficient. One example may provide readily manufactured covers for SIP modules. These modules may be easily assembled by attaching the cover to a top side of a substrate. These SIP modules may have a low-profile, for example when their height is reduced using one or more recesses in a bottom surface of a top of the recess, where the one or more recesses are arranged to accept one or more components. These SIP modules may be made space efficient by placing an edge of a cover near an edge of the substrate and connecting the plating of the cover using side plating on, or vias through, the substrate.

A battery bridge for an electronic device, preferably for an electronic implant, has an electrically conductive first contact element, an electrically conductive second contact element and an insulator. The first contact element and the second contact element comprise a weldable material. In a first state of the battery bridge, the first contact element is distanced from the second contact element via a predefined air gap and the first contact element is electrically insulated from the second contact element by the air gap and the insulator. The battery bridge is formed in such a way that it can be transferred, by welding the first contact element and the second contact element together, into a second state, in which the air gap between the first contact element and the second contact element is closed electrically conductively, at least in part. A method for activating such an electronic device is also disclosed.
