FAQ

• Q1: What are the benefits of etched encoder discs over stamped or laser-cut discs?
  A: Etched discs are burr-free, stress-free, and perfectly flat, eliminating signal noise. They allow for more complex and finer geometries than stamping without tooling costs, and offer better edge quality and faster throughput for fine features compared to laser cutting.
• Q2: Can you produce discs with an absolute position pattern (e.g., Gray code or pseudorandom code)?
  A: Absolutely. Our digital process is ideal for producing complex, non-repetitive code patterns required for absolute encoders with high accuracy.
• Q3: What file format do you require for production artwork?
  A: We prefer vector-based formats like AutoCAD DXF or DWG. We can also work with Gerber files and provide expert DFM analysis on your design.
• Q4: Do you offer any treatments to improve optical contrast for optical encoders?
  A: Yes, we offer post-etch blackening processes (e.g., black oxide on stainless steel) to maximize opacity and contrast for clear signal generation.
• Q5: What is your typical lead time for prototype and production orders?
  A: Prototypes can often be delivered in 1-2 weeks. Our production process is highly streamlined for speed, and we are specifically equipped to manage large-volume orders efficiently without sacrificing quality.
