Abstract
Permanent physical and electrical attachment of electrically conductive contacts of a first component in a RFID device, such as a smart card or smart inlay, is made to the electrically conductive contacts of a second component of the device, for example, a conductive area, such as an antenna. Attachment is achieved by co-depositing metal and electrically conductive hard particles upon the conductive contacts of either the first or second components and then using a non-conductive adhesive to provide permanent bond between the components and their conductive contacts.
