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 has raised edges surrounding orifices. The raised edges are placed against a surface of a substrate to be printed in use of the stencil. The screen printing stencil can be used for printing substrates in the electronic substrate fabrication and electronic assembly industries.
