A library to write Gerber files
Project description
Purpose
A Python library for writing Gerber files.
No need to read the 200 page Gerber format specification.
API much simpler than the Gerber format specification - 8 pages vs 200.
All common pad shapes built-in.
User-defined pad special shapes
100% compliance with the specification, rev 2022.02.
Conservative, robust output files.
Risky constructs that fail in some buggy implementations are not used.
Include standardized meta information needed for fabrication, such as which pads are vias.
Verify whether the input parameters comply with the Gerber spec.
Stateless input (the gerber_writer takes care of the Gerber states).
Example:
from gerber_writer import DataLayer, Circle, RoundedRectangle
trace_width = 0.127
via_pad = Circle(0.508, 'ViaPad')
IC17_toe = RoundedRectangle(1.257, 2.286, 0.254, 'SMDPad,CuDef')
toe_point = (0, 2.54)
via_point = (5.08, 0)
top = DataLayer('Copper,L1,Top,Signal')
top.add_pad(IC17_toe, toe_point, angle=45)
top.add_trace_line(toe_point, (2.54, 0), trace_width, 'Conductor')
top.add_trace_line((2.54, 0), via_point, trace_width, 'Conductor')
top.add_pad(via_pad, via_point)
with open('gerbers\gerber_writer_example_small.gbr', 'w') as outfile:
top.dump_gerber(outfile)
