Upload PCB files( gerber file, .pcb, .pcbdoc or .cam file format)
Thanks for reviewing our PCB capabilities. Please upload your PCB files in the format of gerber file, .pcb, .pcbdoc or .cam file when you go through our online purchase procedures. Please try best to offer gerber file. But if you only have DXP file with (.pcb/.pcbdoc) format, we will use ALtium Designer10.0 software to transfer to gerber.So please avoid higher version than AD10.0 .You can also send your Gerber to your sales rep, but we strongly suggest you order online on the webpages.
