ABSTRACT:
The method includes the step of forming a solid epoxy member on a substrate, the epoxy member having an upper surface of desired configuration. A first metal layer is deposited on the epoxy member with the upper surface thereof conforming to the desired configuration. A layer of epoxy is deposited on the first metal layer and epoxy material from the epoxy layer is removed to create a well, exposing the metal layer on the epoxy member. A metal impression layer is then deposited in the well. The metal impression layer is then removed from the well and affixed to a mounting member as a mold component for injection molding of small structures.
