A display device is further disclosed.

The connector portion of a flex connector may be integrated into a socket, by forming a complete cutout in the socket in which the connector is located, or by forming the socket with a portion having a reduced thickness relative to the rest of the socket, with the connector being positioned in this portion of reduced thickness between the socket and an MLB. Another flex connector may be formed vertically above the first flex connector, mounted to the top surface of the package and clamped in place by a heat sink on top of the stack. Providing both top and bottom flex connectors may multiply the number of available connections for a given footprint. A heatsink positioned on top of the stack may include a spring assembly on a bottom portion to engage specified portions of the stack with a predefined force to ensure correct loading.

A system includes a top printed circuit (PCB) including an array of contact pads, a bottom PCB including an array of contact pads, at least one interposer positioned between the top and bottom PCBs, including: an array of top connectors configured to contact the array of contact pads of the top PCB; an array of bottom connectors configured to contact the array of contact pads of the bottom PCB; and interconnections configured to electrically connect the top connectors and the bottom connectors, at least one spacer element positioned between the top PCB and the bottom PCB and configured to contribute to maintaining a specified distance between the top PCB and the bottom PCB; and at least one fastener of the top PCB and the bottom PCB. The system further includes fasteners configured to press the top PCB, the interposer, the bottom PCB, and the spacer layer together.

An electronic device includes: a circuit board having a wiring board on which wiring is formed, and an electronic component that is electrically and mechanically connected to the wiring via a first solder. A base is provided to accommodate the circuit board, and has a side wall that faces a side surface of the wiring board. A leaf spring arranged on the circuit board, and is configured to be contactable with the base. The leaf spring includes a fixing portion arranged on the circuit board and a pressing portion extending from and connected to the fixing portion and pressing the side wall, and the pressing portion in a biased state toward a housing establishes a contact thereto when the circuit board is put in and accommodated by the base.

The present disclosure relates to phase shifters, antennas, and base stations. One example phase shifter includes a cavity, a built-in printed circuit board (PCB), and a stress relief portion. The stress relief portion is connected to the PCB, and the stress relief portion is configured to reduce a stress generated due to different coefficients of thermal expansion (CTE) of the cavity and the PCB.

A display module includes: a backplate; a backlight module disposed on the backplate; a liquid crystal panel disposed on the backlight module; a frame configured to fix the liquid crystal panel; a circuit board disposed on the backplate; and a conductive part. The conductive part is connected with the backplate or the circuit board, the conductive part includes an elastic portion connected with the liquid crystal panel, and at least part of the elastic portion is located between the liquid crystal panel and the frame and is in a compression state. A display device is further disclosed.

A memory module has pads on the top and bottom surfaces of a module printed circuit board (PCB). The pads match the pin layout of one or more memory devices to be mounted on the memory module. The pads on one surface of the PCB electrically interconnect to the memory device(s), and the pads on the other surface electrically interconnect to pads on a system board, such as a motherboard. With the pad layout on the memory module, the pad layout of the system board can be the same for a memory-down implementation and for a removable memory module. The pad layout provides good signal-to-noise performance and can enable a memory module for low power double data rate (LPDDR) memory, double data rate (DDR) memory, and graphics double data rate (GDDR) memory.

An electrical connector and an assembly method thereof are disclosed. The electrical connector includes a substrate provided with multiple accommodating holes, and multiple terminals. Each of the first terminals has a first insertion portion inserted downward into a corresponding accommodating hole, a first strip connecting portion to be connected to a first strip, and a first soldering portion located outside the corresponding accommodating hole and soldered on an upper surface of the substrate. A bottom portion of the first insertion portion, the first strip connecting portion and the first soldering portion are located on a same first plane, such that the first terminals are not easy to twist when the strip is bent and when being inserted into the substrate, thereby allowing the first terminals to be assembled stably.

Disclosed is a printed circuit board having a holder for a battery, wherein the holder includes first and second contacts connected to conductive traces of the printed circuit board and wherein the holder is embodied such that a battery inserted into the holder is clamped so that poles of the battery on opposite end faces of the battery make electrical contact with the first and second contacts. The battery lies clamped between the contacts on a support region of the printed circuit board and is oriented with reference to the printed circuit board so that an imaginary line connecting the poles of the battery is essentially in parallel with the plane of the support region. The printed circuit board has connected with the support region a rigid first section, which is essentially perpendicular to the support region, and wherein the first contact is arranged on the first section.

A motherboard module is adapted for an M.2 expansion card to configure. The M.2 expansion card includes a connecting end and a fixing end. An edge of the fixing end has a semi-circular hole. The motherboard module includes a motherboard body, a locking member, and an abutting member. The motherboard body includes an expansion card slot, a first fixing hole, and a second fixing hole. The locking member is detachably fixed in the first fixing hole. The abutting member has a first end and a second end. The first end is detachably fixed in the second fixing hole. When the M.2 expansion card is installed on the motherboard module, the abutting member is located between the M.2 expansion card and the motherboard body, and the second end abuts against the M.2 expansion card. An electronic device is further provided.
