VACCO’s PhotoPore® screens and meshes are etched from solid sheets of material offering superior mechanical strength, excellent electrical conductivity, and reliable integrity of pore size regardless of flow characteristics. VACCO’s PhotoPore® screens can be made of titanium, nitinol, stainless steel, Kapton® nickel, copper, or any other material etched at VACCO, see Design Guide.

Patterns are wide ranging, from: round, elongated, hexagonal, square, octagonal, rectangular, and so on. All inside corner radii will be equal to material thickness, and the hole must be equal to or larger then the material thickness. With VACCO you have the flexibility to achieve some transmission and open area issues you cannot achieve through other methods of manufacturing.

Through hole features are normally etched equally (50/50) from both sides of the process sheet. VACCO can etch at different proportions (i.e. 80/20 or 60/40) which can produce conical-shaped through hole features, helping to achieve unique flow characteristics benefiting certain applications. Review the diagram below showing the difference of a 50/50 etch profile compared to a 80/20 etch profile.
