摘要:
A method for making a circuit board comprising: providing a silver clad laminate comprising a substrate and two silver foils; forming at least one through hole on the silver clad laminate, the through hole comprises an annular middle wall and two annular edge walls connected to two sides of the annular middle wall; forming an organic conductive film on the annular middle wall; forming a dry film pattern layer on the second area; plating copper to form a copper circuit layer on the first area, and to form a via hole in the through hole; removing the dry film pattern layer; and etching the second area of the silver foil away. The first area changes to a silver circuit layer. The copper circuit layer and the silver circuit layer define a conductive circuit layer. A circuit board made by the method is also provided.
