Abstract:
A process for forming a patterned thin film structure on a substrate or in-mold decoration film is disclosed. A pattern is printed with a material, such as a masking coating or ink, on the substrate, the pattern being such that, in one embodiment, the desired structures will be formed in the areas where the printed material is not present, i.e., a negative image of thin film structure to be formed is printed. In another embodiment, the pattern is printed with a material that is difficult to strip from the substrate, and the desired thin film structures will be formed in the areas where the printed material is present, i.e., a positive image of the thin film structure is printed. The thin film material is deposited on the patterned substrate, and the undesired area is stripped, leaving behind the patterned thin film structure.
Abstract:
A method for coating substrates having sides of the substrate with unequal adhesion properties includes the steps of non-symmetrically coating the substrate by coating a first side under a first set of coating conditions and coating a second side under a second set of operating conditions wherein the operating conditions used to coat each side are varied so as to compensate for the unequal adhesion properties of the sides. Also, a method for substrate preparation comprising the steps of: providing an annealed thermoplastic substrate base layer having a first surface and a second surface; stabilizing the substrate base layer in an environment having a baseline temperature and relative humidity; drilling vias in the base layer; subjecting the first and second surfaces of the base layer to ion processing so as to remove contaminants caused by drilling the vias and to prepare the first and second surfaces for sputtering; metalizing the base layer by first sputtering at least one metal layer onto the first surface of the base layer and subsequently sputtering at least one metal layer onto the second surface of the base layer said sputtering of the metal layers being controlled so as to prevent the temperature of the base layer from exceeding the annealing temperature of the base layer; allowing the metalized base layer to stabilize in an environment having the baseline temperature and relative humidity an then subjecting the metalized base layer to further processing so as to modify the metal layers into conductive patterns.

Abstract:
A method of 3D printing a flexible electronic device comprises depositing one or more conductive filaments in a predetermined pattern on a substrate, where the one or more conductive filaments comprise a conductive ink formulation comprising a polar solvent, a thermoplastic elastomer, and a plurality of electrically conductive particles. The polar solvent is evaporated to dry the one or more conductive filaments, thereby forming a 3D printed conductive structure on the substrate.
