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.
|
|
|
|
The different layers of the PCB are separated into different files. gerbv
|
|
can load all files at the same time and display them "on top of each
|
|
other". You can independently turn them on and off.
