CPC classification number: H05K1/024 , H05K1/115 , H05K3/0011 , H05K3/10 , H05K3/42 , H05K3/4602 , H05K2201/0183 , H05K2201/09209 , H05K2203/0502
Abstract: A circuit board includes a first dielectric material, a second dielectric material, a third dielectric material, a first external circuit layer, a second external circuit layer, multiple conductive structures, and a conductive via structure. Dielectric constants of the first, the second and the third dielectric materials are different. The first and the second external circuit layers are respectively disposed on the first and the third dielectric materials. The conductive via structure at least penetrates the first and the second dielectric materials and is electrically connected to the first and the second external circuit layers to define a signal path. The conductive structures are electrically connected to each other and surround the first, the second and the third dielectric materials. The conductive structures are electrically connected to the first and the second external circuit layers to define a ground path surrounding the signal path.

Abstract: Provided is a manufacturing method of circuit board, including a first substrate, a second substrate, a third substrate, a fourth substrate, multiple conductive structures, and a conductive via structure. The third substrate has an opening and includes a first dielectric layer. The opening penetrates the third substrate, and the first dielectric layer fills the opening. Multiple conductive structures are formed so that the first substrate, the second substrate, the third substrate, and the fourth substrate are electrically connected through the conductive structures to define a ground path. A conductive via structure is formed to penetrate the first substrate, the second substrate, the first dielectric layer of the third substrate, and the fourth substrate. The conductive via structure is electrically connected to the first substrate and the fourth substrate to define a signal path, and the ground path surrounds the signal path.
