Abstract

A method of manufacturing an electronic component comprising an integrated circuit and a core, includes the steps of providing the integrated circuit having at least two accessible contacts, providing the core, assembling the integrated circuit and the core together by means of an adhesive substance, winding a wire on the core in order to produce a winding, bonding or soldering a first end of the wire to a first one of said contacts and bonding or soldering a second end of the wire to a second one of said contacts.

Claims

1. A method of manufacturing an electronic component comprising an integrated circuit and a core, with the steps of:

providing the integrated circuit having at least two accessible contacts, and

providing the core,

wherein the method includes the following successive steps of;

assembling the integrated circuit and the core together by means of an adhesive substance,

winding a wire on the core in order to produce a winding,

bonding or soldering a first end of the wire to a first one of said contacts, and

bonding or soldering a second end of the wire to a second one of said contacts.

2. The method according to claim 1, wherein assembling the integrated circuit and the core together comprises the steps of placing the integrated circuit on a holding tool, applying a predetermined volume of said adhesive substance to at least one end face of the core and placing the core on the holding tool in such a manner that the adhesive substance on the core gets into contact with an end face of the integrated circuit.

3. The method according to claim 2, wherein the winding and bonding or soldering steps are carried out while the electronic circuit and the core assembled together are carried in the holding tool.

4. The method according to claim 1, wherein an adhesive substance is used having such a pot life that the adhesive joint between the integrated circuit and the core is sufficiently hardened after the bonding or soldering step has been finished so that no mechanical holding forces between the integrated circuit and the core act on the wires.

5. The method according to claim 1 wherein the end face of the core to which the adhesive substance has been applied is kept in a distance from the opposite end face of the integrated circuit so that a gap is provided between both opposing end faces, wherein adhesive substance is provided in the gap.

6. An electronic component realised by the manufacturing method according to claim 1, said electronic component comprising an integrated circuit having at least two accessible contacts and a core, wherein a wire is wound on the core in order to define a winding, wherein a first end of the wire is bonded or soldered to a first one of said contacts and wherein a second end of the wire is bonded or soldered to a second one of said contacts, and wherein the integrated circuit and the core are mounted together by means of an adhesive substance.

7. An electronic component according to claim 6, and wherein the adhesive substance is hardened glue.

8. An electronic component according to claim 6, wherein the integrated circuit and the core are spaced apart and in that the hardened adhesive substance is provided in the gap between the integrated circuit and the core.
