PM1 Precision Stainless Steel Shadow Mask for Thermal Evaporation
Price range: $21.00 through $42.00
Precision Stainless Steel Shadow Mask for Thermal Evaporation
Manufacturing Methods
Stainless steel shadow masks are mainly manufactured using
high-precision chemical etching or laser cutting and welding processes.
Process Specifications
| Process | Material / Thickness | Feature Size | Error | Notes |
|---|---|---|---|---|
| Chemical Etching | 304 Stainless Steel / 0.3 mm | 0.4 mm (400 µm) line width 0.4 mm (400 µm) opening |
30–60 µm | Fast processing and relatively low cost |
| High-Precision Chemical Etching | Stainless Steel | 0.1 mm (100 µm) line width | Solid area: 30 µm Opening area: 60 µm |
Suitable for interdigitated electrode shadow masks. Pattern design should take process error into account. |
| Ultra-High-Precision Laser Processing | Stainless Steel | 0.04 mm (40 µm) line width | 20 µm | Higher precision and higher cost |
Applications
Shadow masks can be used in electron-beam evaporation,
thermal evaporation and magnetron sputtering equipment
for patterned thin-film and electrode fabrication.
- OPV devices
- OLED devices
- Perovskite solar cells
- Photodetectors
- Field-effect transistors
Process Notes
Chemically etched shadow masks generally have a smoother surface
and better flatness, but the price is relatively higher.
High-precision laser-cut and welded masks may have a slightly
rougher surface. They are generally polished and can meet normal
laboratory requirements. They are also suitable for thermal
evaporation electrode deposition and shadow masks with recessed-groove
designs. Customers with special requirements should specify them in advance.
Drawing Requirements
Please provide a CAD drawing whenever possible.
If a CAD drawing cannot be provided, please provide a sketch
that accurately describes the required shadow mask specifications.
