<p>In accordance with the invention, an electronic device (9) having one or more contact pads (12) is adhered to an array of transferable solder particles (31) on a removable carrier sheet (32). The carrier is removed, as by dissolving, leaving solder selectively adhered to the contact pads. In a preferred embodiment the solder-carrying medium is water soluble, and the solder particles comprise solder-coated magnetic particles. Application of a magnetic material while the medium is drying or curing, produces a regular array of solder-coated particles. Using this method, devices having smaller than conventional contact structures can be readily interconnected. <IMAGE></p> |
