SOLDER ELECTRONIC COMPONENTS TO PRINTED CONDUCTIVE INK

Abstract:

Attaching electronic components to a substrate utilizes conductive materials to attach the components and to form traces to allow electrical connectivity between pads receiving the components. Conductive inks are non-solderable and cannot be utilized as solder pads whereas solderable inks are non-conductive. By applying a substrate with conductive ink and then selectively applying a solderable ink on the conductive ink, electronic components may be attached to a substrate that provides mechanical attachment and electrical connectivity which may also be formable or flexible.
