Photo Chemical Milling Process

Our photo chemical milling (also known as photo etching) process uses photolithography and chemical etchants to remove selected metal areas with micron-level precision — no mechanical stress or burrs are produced. This method ensures sharp edges, consistent aperture sizes, and perfect pattern alignment, making it ideal for encoder applications that demand absolute accuracy.

Advantages of Our Photo Chemical Milling Technology

• No burrs or deformation, maintaining optical accuracy

• High repeatability for mass production

• Fine details achievable — micro features down to 0.05mm

• No tool wear or stress, unlike stamping or laser cutting

• Quick prototyping & cost-effective for both small and large runs
