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.

Abstract: An interlayer connective structure is suitable for being formed in a wiring board, in which the wiring board includes two traces and an insulation part between the traces. The insulation part has a through hole. The interlayer connective structure located in the through hole is connected to the traces. The interlayer connective structure includes a column and a pair of protuberant parts. The protuberant parts are located at two ends of the through hole respectively and connected to the column and the traces. The protuberant parts stick out from the outer surfaces of the traces respectively. Each of the protuberant parts has a convex curved surface, in which the distance between the convex curved surface and the axis of the through hole is less than the radius of the through hole.

Abstract: A manufacturing method of a circuit board structure is described as follows. An inner circuit structure including a core layer having an upper and an opposite lower surface, a first patterned circuit layer disposed on the upper surface and a second patterned circuit layer disposed on the lower surface is provided. An insulating material layer is formed on a portion of the first patterned circuit layer. A laser resisting layer is formed on at least a portion of the insulating material layer. A release layer is adhered to the laser resisting layer. A build-up process is performed so as to laminate a first and a second build-up circuit structures on the first and the second patterned circuit layers, respectively. A laser ablation process is performed on the first build-up circuit structure so as to form a cavity at least exposing a portion of the upper surface of the core layer.
