You have a multi-layer PCB design with inner layers and multiple solder mask layers. How should you prepare Gerber files to ensure correct manufacturing?

hard📝 Scenario Q15 of 15

PCB Design - Manufacturing Output

AExport each copper layer, solder mask layers, and drill file separately; verify with a Gerber viewer before sending

BExport only the top and bottom copper layers and send the entire project folder

CExport all layers combined into a single file to simplify manufacturing

DSend the schematic and layout files directly to the manufacturer without exporting Gerbers

Step-by-Step Solution

Solution:

Step 1: Identify required Gerber files for multi-layer PCB
Each copper layer, solder mask layer, and drill file must be exported separately to represent all PCB details.
Step 2: Verify files before manufacturing
Using a Gerber viewer ensures files are correct and complete, preventing manufacturing errors.
Final Answer:
Export each copper layer, solder mask layers, and drill file separately; verify with a Gerber viewer before sending -> Option A
Quick Check:
Separate export + verification = correct Gerber preparation [OK]

Quick Trick: Export all layers separately and verify with viewer before sending [OK]

Common Mistakes:

MISTAKES

Combining layers into one file causing confusion
Sending schematic instead of Gerber files
Skipping verification before manufacturing
