I scanned it fairly quickly to get a good idea of how to interact with the program. That way I had some idea what the icons meant and what functions were available in the user interface. (Okay, I've written documentation before so I figured since it was available I'd look it over. It gave me a pretty quick idea of how the user interactions are structured.) >> One recommendation for now as I have to leave for choir rehearsal--do >> the same thing with additional ground traces north and south of the ESD >> pads on layer 6 as you did on layer 1 to bring the distance between pad >> and ground down from 15mil to around the same as the pad-to-pad spacing >> of the ESD component pads. > > yep sorted. will send you new gerber set, for anyone else to see > (and also make it easier for you, richard) attached screenshot. Beautiful! I think that was the most important change I noticed. I am mainly looking at the HDMI which we have been laboring over the last few months. My next suggestion has an associated question: I notice that north of the long east-west transmission line, at the northern keepout boundary on layer 6, there are a couple of vias that have almost complete ground shield between the vias and the HDMI TX2 pair. Question: What is the fill polygon width for ground fill on layer 6? I can see two fairly simple solutions to complete the ground shield around these vias: 1. Add traces to complete the ground shield between vias and HDMI differential pair. 2. Adjust trace/fill polygon width for ground fill on layer 6 till the ground shield is complete. I'll sleep on it and take another look tomorrow morning. _______________________________________________ arm-netbook mailing list [email protected] http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to [email protected]
