FAQ

• Q1: What copper alloys can you etch?
  We etch pure copper (C1100, C1020), brass, beryllium copper, and phosphor bronze.
• Q2: Can you produce parts thinner than 0.05mm?
  Yes. Our minimum thickness is 0.02mm for copper.
• Q3: Do you offer post-etching treatments?
  Yes. We can provide cleaning, passivation, leveling, and surface finishing as needed.
• Q4: Is etching suitable for high-volume orders?
  Absolutely. Etching is highly repeatable and cost-effective for large quantities.
• Q5: How accurate are your etched copper parts?
  Typical uniformity is ±0.03mm. Tighter tolerances are possible depending on design.
