AdditionalInformationfortheBoardManufacturer
You must also supply the service company with the configuration files
for apertures (name.whl) and drills (name.drl). You can also include the
board file name.brd. This can help to avoid problems with what can be
-
come time-consuming questions. In general, alignment marks (which
are for example defined in layer 49, Reference) or an information field
(in,forexample,layer48, Documentation)canbeincluded.
A text file, such as demo.txt, should contain instructions for the board
manufacturer.
