Abstract:
A circuit board or each circuit board of a multi-layer circuit board includes an electrically conductive sheet coated with an insulating top layer covering one surface of the conductive sheet, an insulating bottom layer covering another surface of the conductive sheet and an insulating edge layer covering an edge of the conductive sheet. An insulating interlayer can be sandwiched between a pair of adjacent circuit boards of a multi-layer circuit board assembly. A landless through-hole or via can extend through one or more of the circuit boards for connecting electrical conductors on opposing surfaces thereof.
Abstract:
In one embodiment, first and second circuit boards may be coupled together. The first circuit board may include a first trace to electrically couple a first integrated circuit to a first via of the first circuit board. In turn, the second circuit board may include a second trace to electrically couple a first contact of a first memory socket adapted to the first circuit board and a first contact of a second memory socket adapted to the first circuit board. This second trace, when the circuit boards are coupled together, is to electrically couple to a first via of the second circuit board, to enable the first via of the second board to electrically couple to the first via of the first circuit board. Other embodiments are described and claimed.

Abstract:
Arranging chip capacitors (20) in a printed wiring board (10) makes it possible to reduce the distance between an IC chip (90) and the chip capacitor (20) and to reduce the loop inductance. Further, since the chip capacitors (20) are received in a thick core board (30), there is no possibility of thickening the printed wiring board.
Abstract:
Interposers and methods of making the same are disclosed herein. In one embodiment, an interposer includes a region having first and second oppositely facing surfaces and a plurality of pores, each pore extending in a first direction from the first surface towards the second surface, wherein alumina extends along a wall of each pore; a plurality of electrically conductive connection elements extending in the first direction, consisting essentially of aluminum and being electrically isolated from one another by at least the alumina; a first conductive path provided at the first surface for connection with a first component external to the interposer; and a second conductive path provided at the second surface for connection with a second component external to the interposer, wherein the first and second conductive paths are electrically connected through at least some of the connection elements.
