A fabrication drawing should identify the board revision, finished dimensions, layer construction or stack-up reference, material, copper, thickness, surface finish, solder mask, legend, hole and profile requirements, acceptance criteria, testing, and any marking or packing needs.
Core drawing information
Use the drawing as the readable statement of finished-board intent and keep it consistent with the digital fabrication data.
- Part number, revision, units, and drawing date
- Finished outline, dimensions, cutouts, slots, and critical tolerances
- Layer count, finished thickness, copper by layer, and stack-up reference
- Laminate or performance requirement and permitted alternatives
- Surface finish, solder mask, legend, and marking
Project-specific notes
Add controlled impedance, via treatment, edge features, cleanliness, electrical test, coupon, microsection, report, packaging, and compliance requirements only where they apply. Resolve conflicting boilerplate before submission.
Next useful step
Final capability, commercial terms, and project records are confirmed against the actual RFQ and written project documents.
