Accepted File Types
PCB files must be compressed into zip folders for our system to accept your order. Include all necessary files in the zip folder:
Gerber, ODB++, or DXF (conversion required, for a fee)
Minimum requirements: all copper layers of the board, a drill file, and an outline (may need to be exported separately)
We also accept the following file types:
.dip from DipTrace (which can be exported as Gerber data)
.bac from PCB Creator software
