Precision Metal Screens and Etched Parts for Electronics
Filtalloy manufactures precision metal screens and drawing-defined etched parts for electronics and microelectronics equipment. Our focus is patterned metal sheets, filter discs, screen plates and custom profiles made by photochemical etching.
Send the component drawing, material grade, thickness, aperture pattern and inspection requirements. We review manufacturing feasibility for your design; the assembly designer defines its electrical, thermal and cleanliness requirements.
Photochemical Etching for Electronics: Component Selection
Etching removes selected areas of metal sheet to create openings and outlines. It avoids a punching die and laser cutting heat-affected zone, but achievable features depend on material, sheet thickness and geometry.
- Precision metal screens: specify aperture shape, opening, pitch, open area and supporting border for screening, ventilation or equipment interfaces.
- Photo etched shims and spacers: provide thickness, outline, locating features and flatness requirements for assembly spacing.
- Aperture plates and custom profiles: define feature positions, datum references and inspection points for equipment alignment or patterned openings.
- Contact or shielding designs: send the complete drawing for feasibility review. Conductivity, spring properties, plating, forming and EMI performance require separate specification and validation.
Choose Features Together with Sheet Thickness
Our published etched-metal range is 0.1–1 mm sheet thickness. For regular filter patterns, the recommended minimum hole diameter is 1.1–1.2 times thickness, with ligaments generally at least the sheet thickness. These are design starting points; drawing review determines the accepted features and tolerances.
Photochemical etching of metal components is distinct from etching semiconductor wafers or fabricating integrated circuits. A metal screen is not automatically suitable for a wafer-contact or high-purity process.
Etched Metal Components and Product Details
Etched Metal
Photo etched mesh, filter discs, screen plates and custom metal profiles. Stainless steel, nickel alloys, titanium and copper-based materials are available subject to design review.
See the product page for current materials, sheet thickness, aperture guidance and formed or welded supply options.

Drawing, Material and Inspection Requirements
- Drawing: send a dimensioned file with units, datums, revision and quantities.
- Material: specify alloy grade, temper, thickness and any required material documentation.
- Pattern: define aperture size, pitch, ligament width, border and outline.
- Acceptance: identify critical dimensions, tolerances, flatness and inspection methods.
- Assembly: specify forming, welds, mounting interfaces and any separately required coating or plating.
- Cleanliness and packing: state permitted residues, handling restrictions, packaging and test requirements.
Inspection and Cleanliness
Agree inspection scope before manufacture, including critical openings, dimensions and surface condition. Cleaning, residue limits and packaging must be specified for the intended equipment. Dimensional inspection alone does not establish semiconductor-process compatibility or electrical performance.
Frequently Asked Questions
Can you manufacture photo etched electrical contacts?
We can review a drawing-defined flat metal part for etching feasibility. Specify the material temper, contact geometry, surface finish and any forming or plating. Finished contact performance requires validation in the intended assembly.
How small can the openings be?
Opening size depends on sheet thickness, material and pattern. Use the current product-page guidelines for an initial design, then send the drawing for review. A single universal micron tolerance does not apply to every part.
Are etched parts automatically clean enough for semiconductor equipment?
No. Define residue limits, cleaning, handling, packaging and qualification tests for the actual process. Suitability must be established against those requirements.
Can you work from an existing sample?
Yes. A sample supports measurement and construction review. Provide the intended function and acceptance criteria; a sample alone may not identify its alloy temper, coating or original tolerance.
Three Ways to Start Your Project
- Requirements-based customization: send the intended function, operating environment and critical features for a new component.
- Drawing-based customization: send the approved drawing and inspection requirements for a new or replacement part.
- Sample-based customization: arrange a sample so we can review its dimensions, construction and missing specifications.
