Divide the sheet into an active aperture field, a solid perimeter and locating features. The clamping land lies outside the active field. A backing supports the foil below; a frame carries its perimeter. Cylindrical and cup-shaped etched parts have their own developed blanks, forming direction and seam or base geometry.

A photoresist pattern defines the openings in a solid metal sheet. Chemical etching removes metal through the patterned areas and forms the aperture walls. Round holes, slots and shaped openings share a continuous metal surface between features. Specify the working face, the exit profile, sheet thickness and remaining ligament width as one geometry.

304 and 316L stainless steel provide corrosion-resistant foil options; plain steel is a separate material branch. The etched-sheet series uses 0.1–1.0 mm stock and a maximum panel layout of 500×600 mm. Fine-opening configurations include 0.03 mm apertures. The fabrication drawing pairs the chosen aperture with its stock thickness, pitch and ligament; each configuration has its own complete dimensions.
Measure aperture at the identified face, pitch, ligament width, sheet thickness and the unperforated border. Inspect flatness, etched wall profile, unintended openings and edge integrity. Locate the active pattern relative to the mounting features so the flow path and peripheral seal are defined together.
The 500×600 mm figure defines the maximum process sheet in this series. Within that outline, the drawing locates the active opening field, solid clamping border and registration holes separately. Photo-etched filter foil uses clear diameter for circular holes, and clear width plus overall length for slots. Pattern data list pitch and remaining ligament in both axes alongside the selected stock thickness, so the blank layout and the installed filtering window share a defined coordinate system.

Include these details when discussing your requirements.
A patterned foil can place openings around fine instrument ports without woven-wire crossover.
Use a controlled repeat pattern when passage geometry matters to particle selection.
Photo tooling can support design iterations of aperture and pitch before a production pattern is frozen.
Etching removes metal through the sheet and along the feature walls. Thickness, working-face opening, exit profile and remaining ligament form a single dimensional specification.
Etched media have openings cut into a continuous sheet. Woven media have interlaced wires, with count and wire diameter defining the structure.
