Abstract: The invention discloses a processing method of a suspended gold finger, and a circuit board, for solving the technical problems of quite high restrictions, very poor versatility and high proneness to waste of resources and increase of the cost existing in a conventional gold finger circuit board. The method comprises the following steps: pressing gold finger copper modules with gold finger copper bars at the internal layer of a multilayer board; processing a group of conduction holes outside a formation area of the multilayer board, wherein the conduction holes are connected with copper board areas of the gold finger copper modules and the gold finger copper bars on the gold finger copper modules; exposing the gold finger copper bars through controlled depth milling; gilding the gold finger copper bars; and removing a non gold finger copper bar portion apart from the formation area of the multilayer board through controlled depth milling to form the gold fingers and prepare a circuit board with the suspension-structure gold fingers.
