Abstract:
A method for connecting a chip to an antenna of a contactless smart card type radio-frequency identification device featuring a chip and an antenna placed on a support made of deformable, non-elastic material, said antenna featuring contacts which are also deformable and non-elastic and which are printed using conductive ink on said support, said method comprising the steps of:positioning the chip provided with contacts made of a non-deformable material, on said antenna support so that said chip contacts are facing the contacts of the antenna, and exerting a pressure on said chip so that said contacts deform said support and said antenna contacts as a result of the pressure, the support and said antenna contacts maintaining their deformation after the pressure exerted is released, thus enabling a maximum contact surface to be obtained between the chip's contacts and the antenna contacts, wherein said support is made of paper and wherein the contacts of the chip are conical in shape.
