PCB Gerber files:


  • Gerber files are the source files for the PCB manufacturing.
  • Gerber files are used to generate a film.
  • Standard files are required for the fabrication
    • TOP Layer
    • Bottom Layer
    • Inner Layers (Power or Ground or routing)
    • Top and bottom Mask
    • Top and bottom Paste
    • Top and bottom silk screen layer
    • Top and Bottom assembly layer (for component assembly)
    • Drill file (Inf on vias and mounting holes)
    • Fab drawing that specify the drill,impedance and stack up information
  • Power and Ground plane - Positive or negative layer.
Typical PCBA: (Assembled PCB)

  • PCBA - Components mounted on PCB.Above board shows the digital circuit.

  • Typical PCBA shows analog/power supply circuits on the board.
