South Korea Develops Nano Conductive Ink to Break Through Printed RFID Field

ABC Nanotechnology, located in Daejeon, South Korea, has successfully developed a nano-conductive ink that can be applied to rapidly growing RFID tags, printed circuit boards (PCBs), and flexible printed circuit boards (FPCBs). Printed electromagnetic shielding materials.

ABC Nanotechnology uses nanosilver as the main body of conductive ink. The finished conductive ink is a colloid. The content of solid matter is less than 30%. Metallic silver is uniformly dispersed in the colloid with a diameter of less than 25 nanometers, so that the ink has an ideal resistivity. The company also showed equipment for printing circuit boards using this ink. The traditional FPCB processing process goes through six processes. At least 90% of the copper raw materials are discarded during this separation process. The use of conductive ink eliminates waste of materials and reduces the number of processes to two, eliminating the need for water-washing of substrate residues. This can increase economic efficiency, significantly reduce manufacturing costs, and reduce environmental pollution during manufacturing.
