Estimating the term…
A single-layer circuit board, multi-layer circuit board, and manufacturing methods therefor. The method for manufacturing the single-layer circuit board (10) comprises the following steps: drilling a hole on a substrate (11), the hole comprising a blind hole and/or a through hole (S1); on a surface (12) of the substrate, forming a photoresist layer having a circuit negative image (S2); forming a conductive seed layer on the surface (12) of the substrate and a hole wall (19) of the hole (S3); removing the photoresist layer, and forming a circuit pattern on the surface (12) of the substrate (S4), wherein Step S3 comprises implanting a conductive material below the surface (12) of the substrate and below the hole wall (19) of the hole via ion implantation, and forming an ion implantation layer as at least part of the conductive seed layer.
A single-layer circuit board, comprising substrate and circuit pattern layer formed on partial surface of said substrate, said substrate is provided with a hole, the hole comprises blind hole and/or through hole, the hole wall of said hole is formed with conductive seed layer, said circuit pattern layer comprises conductive seed layer formed to partial surface of said substrate, wherein said conductive seed layer comprises ion implantation layer implanted below partial surface of said substrate and below the hole wall of said hole.
