Abstract:
The invention relates to a method for producing a security document, wherein a body is created that comprises two superimposed layers, a circuit which is electric and/or has an electronic chip arranged on the interface between the two layers, and a first adhesive between the two layers, which adheres to the two layers and/or the circuit. The method includes a step of depositing a second adhesive which is different from, or has a different behaviour from, the first adhesive in relation to the solvents or the temperature and partially adheres to at least one of the two layers and/or the circuit.
Abstract:
The invention relates to a method for producing an intermediate device comprising an electronic module, said intermediate device being used to receive at least one film or portion of a film or covering layer, said device comprising: a supporting body; at least one area for the interconnection of an electric circuit, borne by the supporting body; and an electronic module connected to said interconnection area by an anisotropic connection material, said material being compressed between said area and the module. The method comprises the implementation of a means for maintaining the compressed state of said anisotropic material and/or a means for isolating said material from the outside of the supporting body.
Abstract:
Radiofrequency device with adjustable LC circuit comprising an electrical and/or electronic module. The invention relates to a communication device with a radio-frequency chip, said device comprising -an insulating support layer, -an electrical and/or electronic radiofrequency circuit on said insulating layer, said circuit comprising plates of an adjustable capacitor and/or an antenna spiral with adjustable inductance, -at least one element for adjusting a tuning frequency of the radiofrequency circuit. The device is distinguished in that said plates and/or spiral are included in an electrical and/or electronic chip card module, and in that said adjusting element connects an intermediate point of the spiral so as to decrease the available inductance and/or splits or links the plates so as to adjust the capacitance.
