METHOD FOR ASSEMBLING COMPONENTS AND ANTENNAE IN RADIO FREQUENCY IDENTIFICATION DEVICES

摘要

The invention provides a method for permanently physically and electrically attaching the electrically conductive contacts (220) of a first component (210) in a RFID device, such as a smart card or smart inlay, to the electrically conductive contacts (214) of a second component (212)of the device. Attachment is made between the first and second components of the device by co-depositing metal and electrically conductive hard particles (218) upon the conductive contacts of either the first (210) or second (212) components and using a non-conductive adhesive (224) to provide permanent bond between the components (210) (212) and their conductive contacts (220) (214). Components (210) (212) of an RFID device may include, for example, a memory chip, a microprocessor chip, a transceiver, or other discrete or integrated circuit device, a chip carrier, a chip module, and a conductive area, e.g., an antenna.
