    摘要: A socket coupled to a circuit board to receive a package of microelectronic device has one or more electrical contacts coupled to its outer surfaces. Each contact provides a low inductance shunt connection from the side of the package to the circuit board. The contact includes multiple adjacent, electrically conductive members, each including a rigid portion and a flexible portion projecting from the rigid portion. The flexible portion is positioned to be in physical contact with a corresponding electrical conductor on an outer surface of the package when the package is coupled to the socket. At least one adjacent pair of the electrically conductive members conduct current in opposite directions to provide mutual inductance. The contact further includes a dielectric layer sandwiched between each two adjacent rigid portions of the conductive members.

    摘要: A series of plated through hole (PTH) vias are interconnected by traces that alternate between a top surface and a bottom surface of a dielectric board. The PTH vias in the series can be positioned to create a collinear inductive filter, a coil-type inductive filter, or a transformer. Multiple, electrically isolated series of interconnected PTH vias can be used as a multi-phase inductive filter in one embodiment. In another embodiment, multiple series of interconnected PTH vias are electrically connected by a linking portion of conductive material, resulting in a low-resistance inductive filter. Ferromagnetic material patterns can be embedded in the dielectric board to enhance the inductive characteristics of the interconnected via structures. In one embodiment, a closed-end pattern is provided with two series of interconnected vias coiling around the pattern, resulting in an embedded transformer structure. A method of producing an interconnected series of PTH vias includes providing a dielectric board having a series of holes. In some embodiments, the board includes an embedded ferromagnetic material pattern. The holes and the top and bottom surface of the dielectric board have a conductive material thereupon. Portions of the conductive material are selectively removed, resulting in the embedded inductive filter and/or transformer structure.

    摘要: 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.
