Good drawings reduce back-and-forth during quotation and help the processing team judge whether the requested micro hole pattern is practical.
Quick Answer
A useful RFQ drawing should show hole diameter, pitch, total pattern area, edge distance, tolerance, foil thickness, material grade and any inspection requirement.
What Buyers Should Confirm
- Use DXF or DWG for 2D cutting paths when available, and add a PDF for human review.
- Call out minimum hole diameter and minimum distance between holes.
- Define whether burr, taper, discoloration or edge rounding is acceptable.
- Include part quantity, prototype quantity and expected production quantity separately.
Processing and Documentation Notes
When the hole pattern is dense, the foil may need special handling to avoid distortion. For very thin stainless steel foil, a small change in bridge width or fixture strategy can make the difference between a feasible and unstable part.

FAQ
Can I send only a screenshot?
A screenshot can support discussion, but DXF, DWG, PDF or STEP files are better for quotation and engineering review.
Do I need to specify inspection?
Yes. If hole size, pitch or edge quality is critical, include the inspection method and acceptance criteria.
