摘要:
The present invention relates to a selectively conductive toy building element, comprising: a body adapted for releasable engagement to at least one other toy building element body or to a corresponding baseplate, the body including at least one conductive portion having at least one contact area adapted to generate pressure on a conductive portion or contact area of an adjacent toy building element body, in such a way that ensures electrical conduction between said toy building elements in a desired location and direction.

A wiring substrate includes a surface layer having electrical insulation properties and a connection terminal having electrical conduction properties and protruding from the surface layer. The connection terminal includes a base portion, a covering portion and a filling portion. The base portion of the connection terminal is made of an electrically conductive first metal and located adjacent to the surface layer so as to extend through the surface layer and protrude from the surface layer. The covering portion of the connection terminal is made of an electrically conductive second metal having a melting point lower than that of the first metal and located so as to cover the base portion. The filling portion of the connection terminal is made of at least one of the second metal and an alloy containing the first and second metals and located so as to fill a hollow in the base portion.

A method of fabricating components for a three-dimensional circuit structure includes providing a printed circuit board (PCB) having a top surface, an opposing bottom surface, and an end section. A first angled channel is formed in the top surface at the end section, with the first angled channel extending to an edge of the end section and dividing the end section into a first end portion and a second end portion. The PCB material is removed from the top surface at the first end portion to form a first support member having an upper surface at a preselected distance below the top surface. A second angled channel is formed in the bottom surface at the end section of the first PCB, with the second angled channel extending to the edge of the end section and being adjacent to the first support member. The PCB material is removed from the bottom surface at the second end portion to form a second support member having an upper surface that is contiguous with the top surface of the PCB. A ramp portion extends between the first support member and the second support member.

A rear board of a blade server, a blade server and a subrack are provided in the present invention. The blade server includes a front board and a back board, the rear board includes a standard ATCA interface, and the rear board is connected to the front board by the standard ATCA interface, a connector configured to connect hard disks is set on the rear board, and a portion of the rear board on which the connector is set is extended outward so as to accommodate at least two hard disks, and the at least two hard disks are connected to the connector. The blade server increase the ability of the heat dissipation ability of the front board, and the rear board supports data backup between the two hard disks and hot plug. This may improve the reliability and easy maintenance about the blade server.
