Abstract
A method of electrically interconnecting conductors, such as electrical components to a printed circuit board. A plurality of first and second conductors are provided which are discrete and at least one of which is made of soft magnetic material that can be temporarily magnetized. The plurality of first conductors are arranged in a predetermined arrangement on a surface of a substrate. An adhesive layer comprised of a mixture is disposed on the surface of the substrate and over the plurality of first conductors. The mixture is comprised of an adhesive and a predetermined concentration of conductive metal particles made of soft magnetic materials that can be temporarily magnetized. The adhesive has a predetermined viscosity which allows the conductive metal particles to be suspended within the adhesive. The mixture is substantially insulating at the predetermined concentration of conductive metal particles. The plurality of second conductors are arranged above the adhesive layer in vertical alignment with the individual conductors of the plurality of first conductors. The adhesive layer is heated to reduce the viscosity of the mixture. A magnetic field is applied such that the condu…
