Explanation

Also known as paste ink. It generally refers to a kind of conductive composition ink, that is, a kind of uniform paste formed by adding conductive particles, solvents, coupling agent and other additive to the organic matrix, and adopting ultrasonic, high-speed stirring and other dispersion methods. Organic matrix materials are usually phenolic resin, epoxy resin, alkyd resin, polyurethime, etc., while conductive particles usually include gold, silver, copper, carbon, etc. After conductive ink is assimilated and dried, the solvent volatilizes and the organic matrix curing. They are closely connected to each other, and the distance between conductive particles becomes smaller. Free electrons form a current in the direction of the applied electric field, thus having a certain degree of conductivity. It can be used as materials for printing circuit, electrode, plating bottom layer, keyboard contact, printing resistance, etc.
