Abstract:
1. A method of making an electrical connection with a microelectronic component arranged on or embedded within a surface of a circuit board layer, the microelectronic component having an electrical contact face accessible on a surface of the microelectronic component oriented away from the surface of the circuit board layer, the method comprising: applying an electrically conducting bump to the electrical contact face of the microelectronic component; and applying a laminate comprising a metal foil holding a coating of an insulating binder to the electrical contact face of the microelectronic component via the coating of the insulating binder under action of at least one of pressure or heat so that the electrically conducting bump penetrates the coating of the insulating binder to contact the metal foil so as to make the electrical connection between the metal foil and the electrical contact face without forming holes in the coating except those due to the bump penetration.
