Frequently Asked Questions

1. Can you manufacture according to custom drawings?

Yes. We support full customization based on CAD drawings (DXF, DWG, PDF, AI formats). Custom slit width, aperture size, thickness, and surface treatments are all available.

2. What is the minimum feature size you can achieve?

For precision etched micro-structures, the minimum feature size can reach 0.01 mm (10 μm), depending on the material type and thickness. Typical tolerances range from ±5 μm to ±10 μm.

3. Which processing method is better: etching or laser cutting?

Chemical etching is ideal for micro-precision features requiring smooth edges and zero mechanical stress. Laser cutting is more suitable for thicker materials and larger features. We recommend the best method based on your specific design requirements.

4. Do you provide rapid prototyping?

Yes. 24-hour rapid prototyping is available for simple designs, subject to material availability and current production workload.

5. What materials are available for custom foil circuits?

Commonly used materials include SUS304 and SUS316 stainless steel, nickel, copper, and molybdenum. Other specialized materials can be evaluated upon request.

6. How do you ensure product quality?

Quality assurance begins with technical sample confirmation. During mass production, we implement strict in-process inspections and final dimensional checks before shipment to ensure compliance with your specifications.
