Abstract

A method of producing a solderable aluminum contact comprises formulating an ink, applying the ink to an aluminum substrate to form an ink layer on a surface of the aluminum substrate, and melting the ink layer. The ink includes a solderable element that is conductive. The melting of the ink layer forms an alloy on the surface of the aluminum substrate including the solderable element.
