Ultra-Thin Etched Stainless Steel & Copper Encoder Discs with Burr-Free Edges

Product Specification

Ultra-Thin Etched Stainless Steel & Copper Encoder Discs with Burr-Free Edges for German market

What is Etching?
Metal etching is a precise, subtractive manufacturing process that uses controlled chemical solutions to remove material, creating intricate and burr-free patterns on thin metal without inducing stress or heat deformation. It is ideal for producing high-tolerance, flat components with fine, complex geometries.

Encoder Discs Overview
Our chemically etched encoder discs are critical parts for optical and magnetic rotary encoders, used to translate rotational position into digital signals. They feature exceptionally precise radial patterns (lines, slots, or windows) that ensure accurate, reliable, and repeatable motion feedback in high-speed systems.

Manufacturing Process

1. Material Preparation: Selection and cleaning of ultra-flat metal substrates.

2. Photoresist Lamination: Application of a uniform light-sensitive layer.

3. Photolithography: High-precision UV exposure transfers the master disc pattern from digital tooling onto the resist.

4. Developing: Removal of exposed/unexposed resist to reveal the pattern.

5. Etching: Precise chemical etching forms the absolute pattern with vertical sidewalls.

6. Stripping & Cleaning: Removal of residual resist and thorough cleaning.

7. Metrology & Inspection: High-magnification optical inspection and critical dimension measurement.
