A reusuable mandrel (1,9) and method of making a reusuable mandrel (1-9) is presented. This mandrel (1-9) has a substrate (1-7) with a conductive film layer (1-3). Upon the conductive film layer (1-3) a dielectric mold resides (1-1). An etched thin film mandrel (5-9) is also presented. This mandrel (5-9) has a substrate (5-5) covered with a conductive film layer (5-3). This conductive film layer (5-3) is etched to form a mold for the device to be manufactured. These mandrels are used by deposition of a metallIc layer thereon. The metallic layer is stripped from the reusuable mandrel; the thin film mandrel (5-9) becomes part of the product. In particular, they can be used to manufacture orifice plates for thermal ink jet printers. |
