Abstract
A method for producing a mini chip card out of a standard card having an embedded semiconductor chip uses a punching die with cutting edges defining the outer contour of the mini chip card. The punching die is adjusted relative to the standard card and with respect to contact surfaces of the embedded semiconductor chip so that the edges of the punching die are at a predetermined distance from the contact surfaces. The punching of the standard card is performed in this adjusted position so that the contact surfaces are in a reference position with respect to the outer contour of the mini chip card. The punching forms the mini chip card in the correct position in the standard card. The mini chip card may initially remain connected to the standard card by thin bars between the cards.
Claims4
A method for producing a mini chip card from a standard card, said standard card having outer edges and having an embedded semiconductor chip with contact surfaces, said contact surfaces being located in agreement with a tolerance window defined by a standard and within a certain tolerance from the outer edges of the standard card, said method employing a punching die with cutting edges defining an outer contour of the mini chip card when produced from the standard card, said method comprising the steps of:
- adjusting a position of the punching die relative to the standard card by positioning the die with respect to the contact surfaces so that the cutting edges of the punching die are at a predefined position with respect to the contact surfaces;
- and
- performing a punching operation with the punching die in the adjusted position to form the outer contour of the mini chip card, the contact surfaces being in a desired position with respect to the outer contour of the mini chip card formed by the punching operation so that the mini chip card is produced from the standard card with a desired positional relationship with respect to the contact surfaces.
