  • Method and stencil design for printing non-planar hybrid circuits
    Patent number: 5368883
    Abstract: The present invention includes a method and stencil design for printing on non-planar hybrid substrates wherein the stencil has a bottom face with a reverse topography to the non-planar hybrid substrate such that the stencil comes in direct contact and rest on the printing area immediately surrounding the print hole formed in the stencil. This eliminates any gap between the stencil and the surface of the substrate where material is to be printed. The stencil may be a metal and may be etched to provide the reversed topography.
