    Abstract: A circuit board for automatically interconnecting electrical components mounted on the circuit board, comprising of a nonconducting emulsion layer sandwiched between two nonconducting outer layers. Electrical leads from electronic components are inserted through holes in one outer layer. Dispersed within the emulsion layer are conducting particles with an elongated length. The emulsion layer's melting temperature is lower than the outer layers allowing movement of the conducting particles when the temperature of the emulsion layer is above the melting temperature, and prevents movement when the temperature is below. Included with the circuit board is an electromagnetic and infrared (EIR) assembly positioned near the outer layer opposite the layer with the electronic components. The EIR assembly has an infrared source and two magnetic field generating devices. One produces a magnetic field parallel to the emulsion layer forcing the conducting particles to line up parallel to the emulsion layer. The elongated length is sufficient so each parallel positioned conducting particle comes into contact with any neighboring parallel positioned particle, thus forming a conducting path. The other produces a magnetic field perpendicular to the emulsion layer forcing the conducting particles to line up perpendicular, electrically isolating the conducting particles from any neighboring particles. Moving the EIR assembly across the circuit board generating the parallel magnetic field forms a conducting path, or generating the perpendicular magnetic field erases any conducting paths. The infrared source is used to raise the temperature of the emulsion layer.

    Abstract: The present invention relates to a printed circuit board arrangement (400) and a method for forming an electrical connection at a printed circuit board. The printed circuit board arrangement comprises a printed circuit board (410) having a first side (411), a second side (412) and an electrical connection (413) electrically connecting a first conductive layer and a second conductive layer (417) of the printed circuit board. The electrical connection (413) comprises a passage (416) extending from an opening in one of the sides of the printed circuit board through the printed circuit board between the first and second layers. Electrically conducting material (414) is formed on the walls (415) of the passage. The electrically conducting material forms a first path electrically connecting the first conductive layer (417) with the second conductive layer (417). At least one first ball 420 is enclosed by the passage. The at least one firstball is electrically conducting and has a diameter which is equal to or smaller than the length and diameter of the passage, wherein the at least one first ball (420) form part of a second electrical path between the first and second conductive layers of the printed circuit board, said second electrical path having a lower resistance than the first path.
