hard📝 Scenario Q15 of 15
PCB Design - Manufacturing Output
You have a multi-layer PCB design. Which combination of output files is essential to ensure correct fabrication?
AOnly one Gerber file for the top copper layer is enough.
BDrill files and a PDF report of the design.
CPDF schematic and a single Gerber file for all layers combined.
DGerber files for each copper layer, drill files, and solder mask files.
Step-by-Step Solution
Solution:
  1. Step 1: Identify required files for multi-layer PCB fabrication

    Each copper layer needs its own Gerber file, plus drill and solder mask files for holes and protection.
  2. Step 2: Evaluate options for completeness

    Gerber files for each copper layer, drill files, and solder mask files include all necessary files; others miss layers or use non-fabrication formats.
  3. Final Answer:

    Gerber files for each copper layer, drill files, and solder mask files. -> Option D
  4. Quick Check:

    Complete multi-layer output = Gerber + drill + solder mask [OK]
Quick Trick: Multi-layer needs separate Gerber files plus drill and mask [OK]
Common Mistakes:
MISTAKES
  • Sending only one layer's file for multi-layer boards
  • Confusing schematic PDFs with fabrication files
  • Omitting solder mask or drill files
