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.
Next Class - PCB Components,Packages,stack up
