PURPOSE: A process for etching aluminium foil for circuit forming in manufacturing an RFID tag antenna is provided to completely remove remaining aluminium during an aluminium etching process, thereby reducing a defective product rate. CONSTITUTION: Industrial water is sprayed to remove etching liquid(S4). Aluminium foil is peeled by spraying peeling liquid(S5). The peeling liquid and a remaining film of a printing layer are removed(S6). The layer is finally washed by spraying pure water(S7). Water is completely removed through a drying furnace.
