Abstract:
1. An electronic device comprising: a casing having a conductive layer made of a mixture of carbon fibers and a thermoplastic resin and a first insulating layer where only the thermoplastic resin is applied on a surface of the conductive layer, the casing further having a number of holes which extend through the insulating layer and into the conductive layer; a printed circuit board coupled to the casing such that the printed circuit board is arranged closer to the first insulating layer than to the conductive layer; one or more electronic components coupled to the printed circuit board; a driving motor; and a metal frame supporting the printed circuit board and the driving motor, the printed circuit board being coupled to the casing by use of a number of screws which are screwed into the number of holes of the casing which extend through the insulating layer and into the conductive layer such that an electrical connection is provided by way of the screws to the conductive layer of the casing.
