Native file file upload is the option that allows you to submit an Eagle, Protel/Altium, OrCAD (with .MAX file extension), Ivex, or Ultiboard design file in place of gerber data.
To save you time we allow you to submit your native design file and we will generate the gerber data for you. If the order is for double sided we will generate the gerber data and proceed with your order.
For multi-layer boards we will generate the gerbers then email you the gerbers along with a pdf to preview before manufacturing. Your order will go on hold in this case pending your approval.
