Abstract
Abstract A carrier element suitable for production in large numbers, e.g. for incorporation in identification cards, having an integrated circuit and the connection leads and contacts necessary for the operation of the circuit. The carrier consists of a single or multilayer insulating material, e.g. a film, carrying the circuit contacted with the connection leads in punched out windows. To protect the circuit from mechanical stress the thickness of the film is greater than or at least equal to the thickness of the integrated circuit plus the thickness of the contacted connection leads.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
126 words
The combination of a card-like member and a carrier element contained therein, said carrier element being formed of insulating material having a window therein; said carrier element having a chip with integrated circuits positioned in said window, and said carrier element further having connection leads formed out of a conductive film applied to the carrier element, said carrier element having at least a pair of layers of insulating material bonded together with said conductive films selectively applied between said bonded layers, one of said layers having perforations through it by which said connection leads can be accessed, said connection leads extending into the window for connection to the chip, said carrier element having a thickness greater than said chip for protecting said chip against mechanical forces.
Claim 2
Dependent Claim
126 words
The combination of a card-like member and a carrier element contained therein, said carrier element being formed of insulating material having a window therein; said carrier element having a chip with integrated circuits positioned in said window, and said carrier element further having connection leads formed out of a conductive film applied to the carrier element, said carrier element having at least a pair of layers of insulating material bonded together with said conductive films selectively applied between said bonded layers, one of said layers having perforations through it by which said connection leads can be accessed, said connection leads extending into the window for connection to the chip, said carrier element having a thickness greater than said chip for protecting said chip against mechanical forces.
Claim 3
Dependent Claim
23 words
The combination of claim 1 characterized in that the window with the carrier element is filled with a mass that can be moulded.
