Abstract:
1. A manufacturing method of a substrate structure, comprising: providing a base material, the base material has a core layer, a first patterned copper layer, a second patterned copper layer and at least one of a conductive via, wherein the core layer has a first surface and a second surface opposite to each other, the first patterned copper layer and the second patterned copper layer are respectively located on the first surface and the second surface, and the conductive via passes through the core layer and connects the first patterned copper layer and the second patterned copper layer; respectively forming a first solder mask layer and a second solder mask layer on the first surface and the second surface on the core layer, wherein a portion of the first patterned copper layer and a portion of the second patterned copper layer are exposed by the first solder mask layer and the second solder mask; forming a first gold layer on the first patterned copper layer and the second patterned copper layer exposed by the first solder mask layer and the second solder mask layer, wherein the base material further comprises at least one through hole, the through hole passes through the first patterned copper layer, the core layer and the second patterned copper layer, and the first gold layer covers an inner wall of the through hole; forming a nickel layer on the first gold layer; and forming a second gold layer on the nickel layer.
