PCB ASSEMBLY / ENGINEERING & PROCUREMENT
Files that make a build ready
One coherent release gives procurement and production a reliable starting point.
The assembly release checklist
| File or requirement | Include | Check before sending |
|---|---|---|
| Gerber & drill files | Copper, mask, legend, outline and drill outputs | Board revision, units and fabrication notes |
| Bill of materials | MPN, manufacturer, references, quantity and package | DNP lines, alternates and supplied parts |
| Placement / CPL | Reference, X, Y, rotation and side | Origin, units and orientation conventions |
| Assembly drawing | Polarity, pin one, special fit and mechanical notes | Consistency with placement and BOM |
| Test specification | Method, firmware, fixtures and pass/fail limits | Coverage and result records |
| Order requirements | Quantity, sourcing model and target delivery | Packaging, shipping and special handling |
Keep one revision across the package
Create a release folder with a short revision identifier. Include the same identifier in your drawing, BOM and order request. If you change a component or board file, send a complete new package plus a change summary so superseded files do not remain in use.
Make the BOM purchasing-ready
Use exact manufacturer part numbers wherever possible. List DNP positions explicitly and explain whether their quantities are excluded. Mark customer-supplied parts and approved alternates in separate fields.
