Abstract
A wiring substrate may include an insulating layer; a differential signal transmission line including a first wiring formed on a first surface of the insulating layer and a second wiring formed on a second surface of the insulating layer, the first wiring and the second wiring transmitting differential signals; and a ground part including a first ground layer and a second ground layer disposed to be spaced apart from the first wiring by the predetermined distance on the first surface of the insulating layer and a third ground layer and a fourth ground layer disposed to be spaced apart from the second wiring by the predetermined distance on the second surface of the insulating layer.
Claims12
A wiring substrate comprising:
- an insulating layer;
- a differential signal transmission line configured to include a first wiring provided on a first surface of the insulating layer and a second wiring provided on a second surface of the insulating layer, the first wiring and the second wiring transmitting differential signals;
- and
- a ground part configured to include a first ground layer and a second ground layer disposed to be spaced apart from the first wiring by the predetermined distance on the first surface of the insulating layer, and a third ground layer and a fourth ground layer disposed to be spaced apart from the second wiring by the predetermined distance on the second surface of the insulating layer.
A wiring substrate comprising:
- an insulating layer;
- a differential signal transmission line configured to include a first wiring provided on an upper surface of the insulating layer and a second wiring provided on a lower surface of the insulating layer;
- and
- a ground part configured to include a first ground layer and a second ground layer disposed to be spaced apart from the first wiring by the predetermined distance on the upper surface of the insulating layer and a third ground layer and a fourth ground layer disposed to be spaced apart from the second wiring by the predetermined distance on the lower surface of the insulating layer,
- wherein the first wiring and the second wiring transmit differential signals and are disposed to be vertically symmetrical to each other on the basis of the insulating layer,
- the first ground layer and the third ground layer are disposed to be vertically symmetrical to each other on the basis of the insulating layer, and
- the second ground layer and the fourth ground layer are disposed to be vertically symmetrical to each other on the basis of the insulating layer.
