Gerber Viewer (gerbv) is a viewer for Gerber files. Gerber files are
|
||
|
|
generated from PCB CAD system and sent to PCB manufacturers as basis for
|
||
|
|
the manufacturing process. The standard supported by gerbv is RS-274X.
|
||
|
|
The basic difference between RS-274D (the old standard) and RS-274X is
|
||
|
|
basically the addition of apertures in RS-274X. It might be possible to
|
||
|
|
make an RS-274X file out of an RS-274D file and an aperture list.
|
||
|
|
|
||
|
|
gerbv also supports drill files. The format supported are known under
|
||
|
|
names as NC-drill or Excellon. The format is a bit undefined and
|
||
|
|
different EDA-vendors implement it different. But basically you need to
|
||
|
|
have the tools definition in the file, then the parser is quite
|
||
|
|
tolerant. The different holes are shown as dots in the (scaled) correct
|
||
|
|
size.
