Title
(EN) METHOD AND APPARATUS FOR PRODUCING A RADIO-FREQUENCY IDENTIFICATION (RFID) TRANSPONDER
(FR) PROCÉDÉ ET APPAREIL DE PRODUCTION D'UN TRANSPONDEUR D'IDENTIFICATION PAR RADIOFRÉQUENCE (RFID)
Abstract
(EN)
A method for producing radio-frequency identification (RFID) transponders arranged on a carrying substrate is disclosed, comprising:providing two substrate areas, each having at least one antenna element with antenna terminals arranged thereon;and providing a dual-sided integrated circuit (IC) having an antenna contact on each of two opposed external surfaces. The IC is arranged on one of the substrate areas, so that one of the antenna contacts comes in mechanical contact with one of the antenna terminals. The two substrate areas are then brought together, thereby bringing the second antenna contact in mechanical contact with second antenna terminal. Finally, heat is applied to the substrate areas in the vicinity of the IC, heating it to a temperature at least equal to a characteristic melting point of the antenna terminals, thereby forming electric contact between the antenna contacts and the antenna terminals.A corresponding apparatus is also disclosed.

L'invention concerne un procédé de production de transpondeurs d'identification par radiofréquence (RFID) disposés sur un substrat porteur, comprenant : la fourniture de deux zones de substrat, ayant chacun au moins un élément d'antenne sur lequel sont disposées des bornes d'antenne ; et la fourniture d'un circuit intégré double face (IC) ayant un contact d'antenne sur chacune de deux surfaces externes opposées. Le CI est disposé sur l'une des zones de substrat, de telle sorte qu'un des contacts d'antenne vient en contact mécanique avec l'un des terminaux d'antenne. Les deux zones de substrat sont ensuite rapprochées, amenant ainsi le deuxième contact d'antenne en contact mécanique avec le deuxième terminal d'antenne. Enfin, de la chaleur est appliquée aux zones de substrat à proximité du CI, en le chauffant à une température au moins égale à un point de fusion caractéristique des bornes d'antenne, ce qui permet de former un contact électrique entre les contacts d'antenne et le terminal d'antenne. L'invention concerne également un appareil correspondant.
