Problems solved by technology

[0011] The problem with all these proposals is that the mechanical tension (introduced during lamination) between the chip, the electronic part and the data carrier body cannot be adequately compensated, since the adhesive and the chip already form a mechanical unit before lamination

Embodiment Construction

[0046] FIG. 1 shows a plan view of a data carrier 1 with an integrated near-field antenna according to the state of the art. The gap 2 is incorporated into the data carrier body 6 . The gap 2 can be produced in different ways, for example by constructing the data carrier body 6 in multiple layers, the respective gap 2 being located in one of the layers. Chip 3 is incorporated into gap 2 . The chip 3 is either an integrated semiconductor chip with contact pads arranged on a substrate, which semiconductor chip is incorporated into the data carrier body 6 such that the chip is contactable by means of an external terminal device. Alternatively, the chip is a molded semiconductor chip which is incorporated into the gap 2 which is electrically conductively connected to the contact points 5 of the data carrier body 6 . The contact point 5 is in turn connected to a near-field antenna 4 arranged in the data carrier body 6 , referred to below as coil 4 .

Abstract

The invention relates to a method for producing a portable data carrier (1), to an inlay for a data carrier and to a data carrier. To this end, a data carrier body (6) with a recess (2) for a chip (3) is provided. A chip (3) is then introduced into the recess (2). In a subsequent step, a cover layer (63) is placed onto the data carrier body (6). Finally, the data carrier body (6) and the cover layer (63) are laminated. The method is characterised in that, after introduction of the chip (3) and before lamination (9), a stabilisation means (8), which remains soft or flexible during lamination and is only hardened or activated after lamination (e.g. by means of UV radiation), is applied to the recess (2) of the core layer (62) in order to prevent mechanical strains.

Description

technical field [0001] The invention relates to a method of manufacturing a data carrier, an inlay for a data carrier and the data carrier itself. In particular, the invention relates to a method for producing a contactless readable data carrier with an integrated IC that can be used as a data page in a chip card, an identification document, an identity card or a passport book. Background technique [0002] A portable data carrier is basically a computer of reduced overall size and resource range, having a microprocessor and at least one interface for communicating with external devices. It usually has no or only basic proprietary user data output. Its external configuration is designed in such a way that it can be easily carried by the user at any time. Preferably, the data carrier is equipped with a corresponding anti-counterfeit function, for example in the form of a smart card, chip card, mass memory card, multimedia card. For example, payment cards such as credit or ...
