How to Chemical Etching Metal Shims?

1. Design Preparation – CAD files are converted into photo tools.
2. Material Selection – Choose the right metal and thickness.
3. Photoresist Coating – Apply UV-sensitive film to both sides of the metal sheet.
4. UV Exposure – Image is transferred using a mask and UV light.
5. Developing – Unexposed areas are removed to create the etch pattern.
6. Etching Process – Chemical solution dissolves unprotected metal.
7. Stripping & Cleaning – Photoresist is removed, and parts are cleaned.
8. Inspection & Delivery – Final inspection ensures all tolerances and specs are met.

The Benefits of Chemical Etching
