ABSTRACT:
To prepare a screen printing stencil, a pattern of resist, having a complementary design to the final screen printing stencil, is applied to a conductive mandrel. A patterned layer is electroformed onto the exposed surface of the mandrel such that the layer corresponds to the exposed orifices of the pattern of resist. The resulting screen printing stencil can have an overgrowth geometry or a straight-wall geometry depending on the type of photoresist employed, and can be used in the electronic substrate fabrication and electronic assembly industries.
