发明名称 SMART CARD, CONNECTION ARRANGEMENT AND METHOD OF PRODUCING A SMART CARD
摘要 The invention concerns a smart card, a connection arrangement and a method of producing a smart card, a semiconductor chip located on a module being inserted into a recess (24) in a card carrier so as to be connected electrically and mechanically. According to a first feature of the invention, during the milling-out of the recess, a contact bump section is exposed (22, 23) such that a reliable connection is provided between the module and induction or antenna coil (11). According to a second and third feature, the required electrical contacts are produced by soldering and the required mechanical contacts are produced by heat-sealing or fusion adhesives. Furthermore, the adhesive is provided with conductive particles and is compressed when the connection is made, such that the necessary electrical contact is brought about. According to a fourth feature, a special reinforcement frame comprising insulating sections is provided. The reinforcement frame is used to increase mechanical stability and absorb torsion forces and stresses which can occur when the card is used. At the same time, the reinforcement frame permits easy contact with strip conductors inside the card, e.g. for inductive elements which form an antenna for contactless data-transmission.
