Before sending Gerber files for PCB manufacturing, engineers must review every detail to avoid delays, errors, or rework. A proper PCB Gerber file checklist ensures production accuracy, reduces mistakes, and improves final board quality.
Check All PCB Layers
Include every layer in the Gerber file set: copper, solder mask, silkscreen, paste, and board outline. For multilayer PCBs, ensure correct layer order to prevent structural issues.
Verify Drill Files
Check drill sizes, hole locations, and plated/non-plated status. Incorrect drill data can cause assembly failures, so thorough verification is essential.
Confirm Board Dimensions
Ensure the board outline includes the final size, cutouts, slots, and mechanical features. Wrong dimensions lead to fitment issues during assembly.
Review Track Width and Spacing
Track width and spacing must match manufacturer capabilities. Very thin traces or narrow spacing may require design adjustments to prevent rejections.
Check Solder Mask and Silkscreen
Verify that solder mask covers required areas and leaves pads exposed. Silkscreen should be readable and not overlap copper. Clean layouts improve assembly and inspection.
Add Stack-Up Details
For multilayer PCBs, include stack-up info: layer arrangement, material thickness, copper weight, and impedance requirements. This ensures the manufacturer meets design specifications.
Include Special Requirements
Share requirements such as surface finish, copper thickness, controlled impedance, material type, testing, or panelization details. Clear communication speeds production and reduces errors.
How TruePCB Supports Gerber File Readiness
TruePCB helps engineers prepare complete and accurate Gerber files. Their support includes:
