The application relates to a circuit board for a server system. The circuit board is adapted to be installed either in a server of a first type or in a server of a second type different from the first type. The circuit board includes connections for receiving assembly groups and a controller to provide a counting order to the connection depending on the server in which the circuit board is connected being a first type or a second type.

A circuit board is a circuit board on which a predetermined circuit unit that causes heat and electromagnetic noise is disposed, and which is to be fixed to a conductive housing with a conductive screw. The circuit board includes: an insulator layer including an insulating plate-shaped base material; a conductor layer having a circuit pattern including a ground portion, which is disposed on at least one surface of the insulator layer; and a screw insertion hole that penetrates the insulator layer and the ground portion, and through which the conductive screw is to be inserted. The ground portion has a slit disposed between the screw insertion hole and the predetermined circuit unit. The ground portion has a ground bridge that electrically connects a portion of the ground portion between the slit and the screw insertion hole and a portion of the ground portion between the slit and the predetermined circuit unit.

An electronic device can include a housing that defines an internal volume. The electronic device can also include a component within the internal volume that divides the internal volume into a first volume and a second volume. The first volume and second volume can be fluidically isolated except at an aperture defined by the component. An air-moving system can produce a positive air pressure in the first volume and a negative air pressure in the second volume.

A base module and an aviation computer system having the base module includes a printed circuit board, an integrated power supply and communication connector, a SMARC connector, and an FMC connector. A power supply circuit supplies the SMARC connector and the FMC connector with power from dedicated power supply contacts of the integrated power supply and communication connector, and a communication circuit connects the SMARC connector to dedicated communication contacts of the integrated power supply and communication connector. In addition, signal lines are provided on the printed circuit board in order to connect dedicated input/output contacts of the SMARC connector to corresponding dedicated input/output contacts of the FMC connector.

A fan expansion card includes a first circuit board and at least one first fan. The first circuit board has at least one through-hole. The first circuit board includes a first connection port having a PCI-E interface. Each of the first fans is disposed at a position on the first circuit board corresponding to the through-hole. The first fan is electrically connected to the first circuit board, wherein an airflow generated by each of the first fans passes through the corresponding through-hole. A motherboard module having the above fan expansion card is further provided.

The embodiments described herein describe technologies for memory systems. One implementation of a memory system includes a motherboard substrate with multiple module sockets, at least one of which is populated with a memory module. A first set of data lines is disposed on the motherboard substrate and coupled to the module sockets. The first set of data lines includes a first subset of point-to-point data lines coupled between a memory controller and a first socket and a second subset of point-to-point data lines coupled between the memory controller and a second socket. A second set of data lines is disposed on the motherboard substrate and coupled between the first socket and the second socket. The first and second sets of data lines can make up a memory channel.

A water block mounting holder with reinforced structure includes a holder body and a reinforcement structure provided on an upper side of the holder body, and is used with a water block to attach the latter to a heat-producing element mounted on a motherboard. The holder body has a hollow-out central opening and a plurality of through holes spaced along an outer area of the holder body for a plurality of fixing elements provided on the motherboard to extend therethrough and fixedly hold the holder body to the motherboard, so that the holder body is connected to the water block with the opening being fitted around the water block. With the reinforcement structure provided on the holder body, the water block mounting holder has effectively reinforced overall structural strength to avoid pressure deformation thereof.
