An electronic device is provided. The electronic device includes a first substrate on which a first electrical element and a first conductive structure, which is configured to surround the first electrical element, are disposed, a second substrate on which a second electrical element and a second conductive structure, which is separably connected to the first conductive structure, are disposed, and a connector which is disposed between the first substrate and the second substrate and electrically connects the first electrical element to the second electrical element.

Embodiments describe an electronic device fastener including a base link bar, and a pair of corner retaining features coupled to the base link bar. Each corner retaining feature includes a base being formed of a planar structure and having a base top surface, a support rail extending from a portion of the base top surface and having a support rail top surface, a fastening feature defined by surfaces of the base and support rail and comprising vacant space extending through the base and at least a portion of the support rail, a guide wall extending from a portion of the support rail top surface, a retaining protrusion extending from the guide wall toward a center line of the electronic device fastener, and a stopper positioned beside the base link bar and at back ends of the base, the support rail, the guide wall, and the base link bar.

To protect memory cards, such as SD type cards, and similar devices from Electrostatic Discharge (ESD), the input pads of the device include points along their edges that are aligned with correspond points on a conductive frame structure mounted adjacent the input pad to form a spark gap. The input pads are connected to a memory controller or other ASIC over signal lines that include a diode located between the input pad and the ASIC and a resistance located between the input pad and the diode. The resistance and diode are selected such that an ESD event at an input pad triggers a discharge across the spark gap before it is transmitted on to the ASIC, while also allowing a high data rate for signals along the signal line.

A high-frequency module 1 includes a component 3a mounted on an upper surface 2a of a substrate 2, a second sealing resin layer 4 stacked on the upper surface 2a of the substrate 2, a component 3b mounted on a lower surface 2b of the substrate 2, a first sealing resin layer 5 stacked on the lower surface 2b of the substrate 2, and a first terminal assembly 6 and a second terminal assembly 7 that are mounted on the lower surface 2b of the substrate 2. The first terminal assembly 6 is mounted on a four-corner portion of the substrate 2 and includes a connection conductor 6a thicker than a connection conductor 7a of the second terminal assembly 7.

A fixing structure for heat dissipation assembly includes a base and multiple female fastener holders. The base has at least one through bore axially extending through an upper and a lower surface thereof, as well as coupling holes located outside the through bore and respectively having an engaging element disposed therein. The female fastener holder has a lower side formed with coupling protrusions corresponding to the coupling holes. The coupling protrusion has a guiding groove radially provided thereon and having a lower and an upper end recess for engaging with the engaging element in the corresponding coupling hole. The engaging elements in the coupling holes are guided by the guiding grooves to move from the lower to the upper recesses when the female fastener holder is turned relative to the through bore and the coupling holes on the base, bringing the coupling protrusions to axially insert into the coupling holes.

An integrated circuit assembly may be formed comprising at least two integrated circuit packages, wherein the at least two integrated circuit packages share a heat dissipation device. In one embodiment, the at least two integrated circuit packages may be electrically attached to an electronic card to form an intermediate integrated circuit assembly. In a further embodiment, the integrated circuit assembly may comprise at least one intermediate integrated circuit assembly electrically attached to an electronic board.

An independent loading mechanism for use with a CPU connector includes a metallic frame cooperating with a back plate module to sandwich a printed circuit board therebetween. A plurality of screw nut units are provided around the four corners of the frame. A plurality of hollow spacers are secured to the corresponding through holes of the frame so as to allow the corresponding screw nut units moveable relative to the frame along the vertical direction within a range larger than a thickness of the frame, thus avoiding improper interference between the screw nut units and the corresponding screw posts of the back plate module during sequential screwing.

A light source module includes a light-emitting device having an upper surface and a lower surface and including: at least one light-emitting element and a plurality of conductive regions on the upper surface of the light-emitting device; a mounting substrate having an upper surface on which a lower surface side of the light-emitting device is located, the mounting substrate including conductive patterns on the upper surface of the mounting substrate, each conductive pattern including a device-side connecting portion and an external side connecting portion; and a plurality of conductive members each having a first end bonded to a respective one of the device-side connecting portion and a second end opposite to the first end, the second end being in contact with a respective one of the conductive region by elasticity to electrically connect the respective one of the conductive regions and a respective one of the conductive patterns.
