  • Electroformed multilayer spray director and a process for the preparation thereof
    Patent number: 5685491
    Abstract: A spray director incorporates structure that generates upstream turbulence for control of spray distribution and spray droplet size. A method of fabricating spray director utilizes a multilayer resist process in conjunction with a multilayer electroforming process.
    Type: Grant

  • Electroformed multilayer flow regulator incorporating force-generating means for selectively constricting the fluid flow path, and a process for the preparation thereof
    Patent number: 5622611
    Abstract: A zero sack volume fluid flow regulator generates upstream turbulence for control of fluid flow, fluid spray distribution and fluid droplet size. The fluid flow regulator includes a seal layer for selectively controlling fluid flow. The seal layer is resiliently movable relative to a base layer to selectively constrict a turbulence inducing intermediate channel within the regulator and selectively control fluid flow. A method of fabricating the fluid flow regulator utilizes a multilayer resist process in conjunction with a multilayer electroforming process.

  • Method for preparing a screen printing stencil
    Patent number: 5478699
    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.

  • Method for preparing and using a screen printing stencil having raised edges
    Patent number: 5359928
    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.
