Abstract:
The hollow multilayer printed wiring board is composed of plural print boards (1), (2), (3), (4) laminated with a predetermined spacing therebetween, each of which has a signal-conducting pattern (6) formed on at least one surface thereof and a land-conducting pattern (7) formed on at least one surface thereof. The board has through-holes (10) which are plated to connect with the land-conducting pattern and each of the through-holes and a plated through-hole in at least one board of the boards adjacent thereto are positioned on a straight line so as to provide a plated through-hole or an interstitial wire hole (12), (13). Formed on at least the upper- and lower- end surfaces of each through-hole (10) are low melting-point metal layers which function as conductors among the signal conducting patterns in 2 or more of the plural boards and as layer-bonding materials for the plural boards. The laminated boards, except at least one of the outer sides, is made of a heat-proof organic plastics-sheet or an insulated metal.

Abstract:
Examples are disclosed that relate to magnetically aligned switching circuits. One disclosed example provides an electronic component comprising a first terminal, a second terminal, and a deformable host material arranged between the first terminal and the second terminal. Aligned magnetically within the host material is an ensemble of particles each comprising a ferromagnetic material, each particle having greater electrical conductivity than the host material. The ensemble of particles is configured to form at least one complete conduction path from the first terminal to the second terminal.
