In order to fit my circuit in my enclosure neatly I need to create it as two PCBs connected by ribbon cable. It's logically one circuit. It certainly makes sense two design it using a single schematic. And ideally I'd like to have both boards in the same .brd file, I think this will make it easier to visualize and maintain the board layout. How should I arrange the board file? Should I draw a second rectangle on the dimension layer to represent the second board? Or maybe draw one rectangle and then draw a line thru it to divide it in two? I've been using PCBWay for production and I understand they support V-Scoring and Tab Routing, are these a good solution for my case and if so, where could i find info on how to define them using Eagle?
Related to this, I'm wondering how to indicate a ribbon cable (or any inter-board connection) in such a way that while it will form a logical part of the schematic Eagle won't draw airwires between my boards. The airwires will simply go to the connectors where the ribbon cable terminates.
I really appreciate any guidance. I'm quite new to Eagle and I'm not sure where to look for more info on this. Thanks!
