PRINTED CIRCUIT BOARD ELECTRICALLY CONNECTED TO THE GROUND OF ELECTRONIC DEVICE

摘要

There is provided a printed circuit board (PCB) coupled with an electronic device. The PCB includes: a first ground layer extended in one direction; a dielectric layer laminated on the first ground layer and extended in the same direction of the first ground layer; a signal transmission line laminated on the first dielectric layer and extended in the same direction of the first dielectric layer; and a cover layer covering the first ground layer. A part of the cover layer is removed and a part of the first ground layer is exposed via the removed part. The exposed part of the first ground layer is in electrical contact with a ground of the electronic device.
