Abstract

A manufacturing method of the thin fan includes the steps of: providing a plastic material containing a plurality of metal particles; processing the plastic material to form a housing; removing a part surface of the housing and forming a layout area and an extended circuit on the housing, wherein one terminal of the extended circuit connects to the layout area; disposing a first signal connecting structure on the housing, wherein the first signal connecting structure connects to the other terminal of the extended circuit; and disposing a metal layer on the layout area and the extended circuit.

First claim

What is claimed is:

1. A thin fan, comprising: a housing composed of a plastic material containing a plurality of metal particles, the housing comprising: a layout area which is an integral part of the housing, wherein a first part of the metal particles is exposed to the layout area, an extended circuit which is an integral part of the housing, wherein a second part of the metal particles is exposed to the extended circuit, and a first terminal of the extended circuit connects to the layout area, a first signal connecting structure, wherein a terminal of the first signal connecting structure connects to a second terminal of the extended circuit, and a metal layer disposed on the layout area and the extended circuit and binding with the exposed metal particles; a stator disposed in the housing; and an impeller covered by the housing.

2. The thin fan of claim 1 , wherein the housing further has a protrusion portion, and the first signal connecting structure is disposed on the protrusion portion.

3. The thin fan of claim 1 , wherein the housing comprises a cable, and the cable is connected to the first signal connecting structure.

4. The thin fan of claim 1 , wherein the housing further comprises a fixing unit, and the first signal connecting structure is disposed on the fixing unit.

5. The thin fan of claim 1 , wherein the housing comprises a first surface and a second surface opposite to the first surface, the layout area is disposed on the first surface, the first signal connecting structure is disposed on the second surface, and the extended circuit is extended from the first surface to the second surface.

6. An electronic system, comprising: a thin fan comprising: a housing composed of a plastic material containing a plurality of metal particles, the housing comprising: a layout area which is an integral part of the housing, wherein a first part of the metal particles is exposed to the layout area, an extended circuit which is an integral part of the housing, wherein a second part of the metal particles is exposed to the extended circuit, and a first terminal of the extended circuit connects to the layout area, a first signal connecting structure, wherein a terminal of the first signal connecting structure connects to a second terminal of the extended circuit, and a metal layer disposed on the layout area and the extended circuit and binding with the exposed metal particles; a stator disposed in the housing; and an impeller covered by the housing; and an electronic device having a second signal connecting structure connecting with the first signal connecting structure.

7. The electronic system of claim 6 , wherein the housing further has a protrusion portion, and the first signal connecting structure is disposed on the protrusion portion.

8. The electronic system of claim 6 , wherein the housing comprises a cable, a first terminal of the cable is connected to the first signal connecting structure, and a second terminal of the cable is connected to the second signal connecting structure.

9. The electronic system of claim 6 , wherein the housing further comprises a fixing unit, and the first signal connecting structure is disposed on the fixing unit.

10. The electronic system of claim 6 , wherein the housing comprises a first surface and a second surface opposite to the first surface, the layout area is disposed on the first surface, the first signal connecting structure is disposed on the second surface, and the extended circuit is extended from the first surface to the second surface.
