Abstract:
The invention relates to the arrangement of a semiconductor in a housing which comprises a Faraday shield-type screen surrounding the housing or suitable damping elements in the feed lines or both means can be used at the same time. In this manner, especially a chip card module housing can be provided with a screen. A semiconductor 1 is mounted on a chip support 2 and a sealing compound 3 is injection-molded around said semiconductor. The exterior of said sealing compound is provided with an electroconducting coating 4 which is linked with a metal layer 7 on the interior of the chip support.
Abstract:
The invention relates to a semiconductor chip (1) comprising a fingerprint sensor. Said chip is arranged in the card body (2) in such a position that when the chip card is bent, the load on the chip inside the entire arrangement of card and chip is minimised in such a way that sufficient security against fracture is achieved, at least in terms of the bending tests necessary for the ISO norm. To this end, a recess (3) is provided in the card body, in which the semiconductor chip is applied, preferably without a housing, in an adapted selected depth (d).
Abstract:
A contactless data storage medium has at least two antennas, in each case for different transmission bands. This makes it possible to configure a data storage medium such that it can be operated with read/write units that operate in accordance with different standards. At least two of the antennas form a unit, so that a configuration such as this can be produced at very low cost.
Abstract:
Process for producing a structured metal layer on a substrate body, in which either a structured bonding layer is applied to the substrate body, in order for a metal foil or a metal powder to be fixed on this bonding layer, or in which a metal foil or a metal layer is applied to the entire surface of a substrate body made from a plastics material and is pressed onto the substrate body with the aid of a structured, heated ram and fixed by a subsequent setting of the substrate body. The metal layer is structured by mechanical removal of those regions of the metal foil or of the metal powder which are not joined to the adhesive or to the substrate body.
Abstract:
The invention relates to a chip module comprising a semiconductor chip (4) which is fixed to a main side of a flat expanded substrate (1). A second component (2) provided for receiving, outputting, reflecting or partially screening electromagnetic radiation, e.g. a radiation sensor or an optical display device, is applied to the same main side of the substrate and is connected to the semiconductor chip. The substrate must be permeable to a sufficient extent to the radiation in question, at least in a region (10) which is occupied by the second component.
Abstract:
A strip conductor (4) is sprayed by a stencil mask or focussing spray device on the surface (3) of a plastic card body's (1) substrate in a gradually increasing thickness. For this purpose a suitable metal particle suspension is used that is a type of varnish made up of metal particles, a solvent and a polymer binder that causes the metal particle suspension to harden off after being sprayed on.
Abstract:
Card body (1) has recess (2) to take up system component (5). System component does not have electrical connection to card body. Component contains chip module with external contacts, antenna coil, display, input unit, power source or converter, sensors, etc. which are electrically connected to each other by conductors (4) on base plate (6) to form system.
Abstract:
The chip module comprises a semiconductor chip, which is fixed on a main side of a substrate of planar extent. A component, which is provided for taking up, emitting, reflecting or partially shielding electromagnetic radiation, e.g., a radiation sensor or an optical display device (display), is provided on the same main side of the substrate and is connected to the semiconductor chip. The substrate is transmissive to the relevant radiation to a sufficient extent and at least in a region occupied by the component.
