Abstract:
Electrically conductive elements on two substrates can be electrically interconnected by an adhesive tape containing electrically conductive equiax particles that are individually positioned in the adhesive layer in a predetermined pattern. Each particle is harder than the elements it is to interconnect, so that hand pressure causes the particles to penetrate into the elements, thus creating a reliable electrical connection. Particularly useful particles are glass beads having a metallic coating that is from 0.1 to 2 µm thick.

Abstract:
A multilayer printed wiring board comprises at least one layer with interlayer connection pattern (200, 300) at the basic grids. The interlayer connection pattern (200, 300) has a clearance (62, 204, 304) when a small diameter through hole (60B) is formed and has a land part (63, 205, 303) contacted to the through hole wall (61A) when a large diameter through hole (60A) is formed. In order to obtain interlayer connection or non-connection, the diameter of a through hole is varied.

Abstract:
The present invention is directed to an apparatus and method for connecting integrated circuits placed on opposite sides of a circuit board through utilization of conduction elements embedded in the circuit board and extending from one surface of the board to the other. Conductive traces extend along the surface of the circuit board from the conduction elements to the integrated circuits. The conductive traces may be formed from multiple conductive layers.
