Abstract:
The invention relates to a non-conductive substrate forming a strip or a panel, on which a plurality of carrier elements, especially for installation in a chip card, are configured, said carrier elements being formed by a respective border line. Said substrate has a contact face and opposite said contact face an insertion face. The insertion face is provided with a conductive insertion face plating and said insertion face plating is configured in such a manner that the contacts of an integrated circuit to be applied to the insertion face later on and the insertion face plating are electrically contacted by a flip-chip connection.
Abstract:
An arrangement with a substrate carrier (S) comprising a first surface (O1) on which outer contact elements (AK) are disposed, a second opposite surface (O2) on which chip contact elements are disposed, whereby the contact elements of the two surfaces are electrically interconnected (D) through the substrate (S), and a chip (IC), whereby the side (K) which is provided with contact points (B) faces the second surface and is electrically connected to the chip contact elements (CK) and whereby the thickness (D2) of the chip is greater than the thickness of the substrate (S). The contact points (B) of the chip (IC) are made of a metal which has a different degree of hardness than that of the chip contact elements (CK).
Abstract:
The invention relates to a flat support, especially for a chip module for use in chip cards. Said flat support has a first main side and a second main side. A number of first metallic coatings are provided on the first main side, with a corresponding number of second metallic coatings being provided on the second main side. The lateral recesses in the flat support are dimensioned in such a way that the flat support can be processed further by an SMD assembly machine. As a result, it is possible to use advantageous materials and current working methods. It is also possible to achieve a very high throughput with an SMD assembly machine.
Abstract:
The invention relates to the flip-chip mounting of semiconductor chips. In order to protect against mechanical stress or damage and to electrically insulate, a protective layer (7) is applied to the rear side of the semiconductor chip (2). This protective layer can also be provided on the flanks (8) of the semiconductor chip. The protective layer can be applied before starting the entire assembly process sequence or when the semiconductor is fixed upside down to a support (1).
Abstract:
A method for producing a chip module includes punching a chip carrier to form a chip carrier fixing section and chip carrier contact sections spaced apart from the chip carrier fixing section by slots defining a given distance. The given distance is subsequently reduced to a dimension preventing a flow through of a sealing mass by a swaging operation carried out at least in a region close to the slots.
