Method for forming a conductive pattern
A method for forming a conductive pattern on a substrate ( 208 ) includes providing an image pattern for imaging on the substrate; imaging the image pattern on the substrate creating imaged areas; spraying functional material ( 240 ) on the substrate that diffuse molecules of the functional material into the imaged areas and wherein the functional material is in a form of liquid; and applying electro-less copper coating that builds conductive material traces on the imaged areas on the substrate.
1. A method for forming a conductive pattern on a substrate comprising:
providing an image pattern for imaging on said substrate;
imaging said image pattern on said substrate creating imaged areas;
