Abstract
A mechanical-laser structure on a printed circuit board and a carrier. A method for fabricating the mechanical-laser structure includes the following steps. A substrate is provided. A first through hole is formed in the substrate by mechanical drilling. An epoxy plug is formed within the first through hole. A conductive layer is formed on the substrate by compression. The conductive layer is patterned to form conducting wires and exposes the epoxy plug. A micro via is formed within the epoxy plug by laser drilling.
