Data Formats 

Several common formats exist for printed circuit file transfer. CAD files are fine as long as they are from a Protel version or some type that can be converted.  However we cannot convert all types of CAD files.

Gerber files are the most common type of printed circuit file transfer format.  These can be sent as RS-274D or RS-274X.  The X version has the benefit of having embedded apertures. RS-274D requires that you send a list of apertures with your Gerber files.  We can do nothing but guess if there is no aperture list.  We do not, as a rule, edit Gerber files but can, if your files are compatible with our CAD system.

Drilling files come in various types, too.  The Excellon leading zero format is most common. We can accept any similar type of drill file. Drill files are simply a list of X-Y coordinates sorted by size.  If required they can be edited and generated by hand, but this is expensive. Alternatives include DXF and Postscript files and non-computer assisted design.  Please contact us if you have non- standard or older design materials.

Please send a FAX proof of your design so that we know what it should look like.  We can't always tell how it should look from uploaded data.  Unfortunately, it is difficult to use the product of any drawing software or CAD systems not specifically designed for printed circuits.  Please contact us for specific information regarding your needs.
