Abstract:
An interposer includes two separate sets of pins, and inserts into two sockets on a printed circuit board. One set of pins supplies power to a step down converter (SDC) mounted on the interposer. The second set of pins provide inputs and outputs to an integrated circuit mounted on the interposer. One or more conductive traces in or on the interposer electrically connect an output of the SDC to an input of the integrated circuit, thus supplying regulated power to the integrated circuit through the interposer. The SDC and integrated circuit can be directly mounted on the interposer, or either or both can be mounted on packages that connect to the interposer. The SDC and integrated circuit can be flip chips or can be connected to the interposer or package using wirebonds. The packages can be pinned or connectable by solder bumps.

Abstract:
An apparatus having a thin metal frame has an opening and a protective rail on each end. Four guide posts extend from the lower surface of the frame to a plate which is spring-biased away from the frame. The plate has pin holes which are arrayed for a particular electrical component having contact pins. The component is loaded into the apparatus by extending the pins through the opening and into the pin holes in the plate. The rails may be flexed outward to accommodate the component before snapping onto and around the ends of the component to fix it from movement relative to the apparatus. The guide posts extend beyond the tips of the pins to provide stand-off protection. The tips of the guide posts are placed in a socket and the assembly is pressed into the socket until the pins seat in it. As the pins are inserted into the socket, the plate is pressed toward the frame to collapse the springs. The apparatus is left permanently installed with the component in the socket.
Abstract:
An adjustment fixture for aligning pins on a protector panel to facilitate insertion of a printed wiring board thereon. The adjustment fixture includes an alignment comb having a plurality of substantially parallel beams, each having a thickness. The comb is placed between rows or columns of pins on the protector panel to straighten and impede unintended displacement or movement of the pins. A beam receptacle brace is provided for attachment to an end of the beams so as to maintain the beams in an appropriate fixed spacing so that the printed wiring board can be mounted to the pins.
