Abstract

A flexible charging pad and a manufacturing method thereof are provided. The manufacturing method of the flexible charging pad includes: providing a double-sided tape to form an adhesion layer, one of two isolation papers is attached on the first adhesion surface, and another of the two isolation papers is attached on the second adhesion surface; removing the isolation paper attached on the first adhesion surface, and attaching a conductor on the first adhesion surface; attaching a first pad layer on the first adhesion surface to cover the conductor, the conductor is disposed between the first pad layer and the adhesion layer; disposing an adhesive to cover the conductor and the first pad layer, and to form a molded layer.

First claim

What is claimed is:

1. A flexible charging pad, comprising:
an adhesion layer having a first adhesion surface and a second adhesion surface respectively located at two opposite sides of the adhesion layer;
a conductor attached on the first adhesion surface;
a first pad layer attached on the first adhesion surface and covering the conductor, wherein the conductor is disposed between the first pad layer and the adhesion layer; and
a molded layer covering the conductor and the first pad layer, wherein the conductor and the molded layer are separated by the first pad layer and in not contact with each other.

2. The flexible charging pad according to claim 1 , further comprising a second pad layer attached on the second adhesion surface.

3. The flexible charging pad according to claim 2 , wherein the second pad layer is made of fabric.

4. The flexible charging pad according to claim 1 , wherein the adhesion layer is a double-sided tape.

5. The flexible charging pad according to claim 1 , wherein the conductor is a metal coil formed by winding a metal wire.

6. The flexible charging pad according to claim 1 , wherein the conductor includes a cladded conductive wire with a heat-resistant temperature of 240° C. or higher.

7. The flexible charging pad according to claim 1 , wherein the first pad layer is made of fabric.

8. The flexible charging pad according to claim 1 , wherein the molded layer is made of silicone.
