If you create your circuit board layout with the Sprint Layout program from ABACOM, please observe the following tips. Basically, it makes sense to use all the prescribed standard-layers of sprint Layout.
We are happy to take care of generating the production data (Extended Gerber) for you. You just have to send us your *.lay file along with your order. All further steps are taken care of by our CAM engineers.
We naturally import your ODB++, Gerber-, Target-, Eagle-, IPC-2581- and Sprint layout data free of charge!
