Abstract
The present invention generally includes a process in which a mandrel for semi-additive construction of circuitry is fabricated by laminating shim stock or foil of stainless steel onto a suitable deformable substrate such as a polyimide glass board. Dimples for making raised features on circuitry are formed in the mandrel with a tool. The use of shim stock makes the mandrel relatively light and suitable for automated processing similar to that used to construct circuits on circuit boards.
