METHOD FOR MAKING CONTACTLESS CARDS

摘要

The invention concerns a method for making a contactless chip card, more particularly a method for making a contactless chip card comprising an integrated circuit (3) and an antenna (2), which consists in producing metal-coated bumps (5) on two contact pads (4) of the chip (3). The invention is characterised in that the chip (3) connection to the antenna (2) is produced by embedding the metal-coated bumps (5) in the antenna (2) thickness, when the chip (3) is being mounted on said antenna (2). Said method provides good quality electrical connection between the chip (3) and the antenna (2):
