I've got a PDF file with a PCB layout I'de like to produce - however, I need the file in Gerber format first. Is there an easy way to convert between the two? I've found this: https://swannman.wordpress.com/projects/pdf2gerb/ - does anyone have some experience with it? Does it work well? Are there better alternatives?
It seemed to work OK on the PDF provided in the example - the Gerbers looked OK when I imported them into GC-Prevue. However, when I created a PDF file from a PCB designed in the Pulsonix software I use, and converted it with pdf2gerb.pl, the resultant Gerber file wouldn't import into GC-Prevue.
There are some PCB manufacturers which can work from artwork supplied as Postscript files. You could convert the PDF file to Postscript by printing it to a file, using a Postscript driver.
The best way is to ask the company that did the layout for Gerbers or CAD originals. Most companies that sell evaluation boards for their chips (e.g. TI, Altera) will do this.
It's not directly possible, as a set of gerber files (including the drill file, which I count as a "gerber" even though it isn't really) contain more information than the average PDF, for example drill sizes and parameters of vias.
