Abstract:
A method for making an electronic assembly includes applying a protective layer including an organosulfur compound to at least a portion of a patterned conductive interconnect circuit, wherein the conductive interconnect circuit overlies at least a portion of a conductive layer on a substrate, and wherein the conductive layer includes nanowires; and engaging an electrical contact of an electronic component with the protective layer to electrically connect the electronic component and the patterned conductive layer.
Abstract:
Methods of achieving precision registration in a roll to roll process for making patterned substrates by depositing first and second inks in a predetermined pattern, the predetermined pattern having fiducial marks and main pattern marks. One of these inks prints the fiducial marks onto a substrate while another ink prints main pattern marks on the same substrate such that the predetermined pattern bears a predictable spatial relationship to the pattern of fiducial marks. Consequently, even if the ink forming the predetermined pattern is invisible, or has such low contrast with the substrate that it is effectively invisible, or even has been dissolved away in a subsequent processing step, it is still possible to know where the predetermined pattern is by referring to the pattern of fiducial marks. Touch screen displays including patterned substrates prepared of the methods are also disclosed.
Abstract:
Electrically conductive patterns formed on a substrate are provided with a reduced visibility. A region of a major surface of the substrate is selectively roughened to form a roughened pattern on the major surface of the substrate. Electrically conductive traces are directly formed on the roughened region and are conformal with the roughened pattern on the major surface of the substrate.
Abstract:
An electronic assembly includes a substrate having in a first zone a low contrast first conductive pattern; a high contrast fiducial mark in a second zone of the substrate different from the first zone, wherein the fiducial mark and the first conductive pattern are in registration; and a second conductive pattern aligned with the first conductive pattern.
Abstract:
A method for making an electronic assembly includes applying a conductive adhesive to a resist layer overlying a patterned conductive nanowire layer on a substrate and engaging an electrical contact of an electronic component with the conductive adhesive to provide an electrical connection between the electronic component and the conductive nanowire layer.
