  • Patent number: 12004296
    Abstract: A printed circuit board includes: an insulating member; a first wiring layer disposed in the insulating member, and including first and second pattern layers spaced apart from each other based on a thickness direction of the printed circuit board; and a second wiring layer disposed in the insulating member, and spaced apart from the first pattern layer over the first pattern layer based on the thickness direction. Based on the thickness direction, an insulation distance between the first pattern layer and the second pattern layer is smaller than an insulation distance between the first pattern layer and the second wiring layer, and each of the first and second pattern layers is thinner than the second wiring layer.
