Manufacturing method of substrate structure, substrate structure and metal component
A manufacturing method of a substrate structure including the following steps is provided. A chemical surface treatment is performed on a metal base such that a passivation layer is formed on a surface of the metal base. The metal base is assembled to a substrate. A metal pattern is formed on the substrate, wherein the metal pattern is separated from the metal base. A substrate structure and a metal component are also provided.
1. A manufacturing method of a substrate structure comprising:
submerging a metal nut in a thiol compound solution to perform a chemical surface treatment on the metal nut with thiol groups of the thiol compound solution to form a passivation layer chemically bonded to a surface of the metal nut, wherein the passivation layer having a thickness ranging from 0.1 nm to 5 nm completely encapsulates the metal nut;
physically screwing the metal nut that is encapsulated by the passivation layer into a substrate; and
forming a metal pattern on the substrate, wherein the metal pattern is separated from the metal nut and the passivation layer.
2. The manufacturing method according to claim 1 , wherein the step of forming the metal pattern on the substrate comprises electroless plating.
