A late response... For mask changeclearsize() seems not to act on distance of mask relief to copper but on total relief size. So changeclearsize(selected,8,mil) will not make the relief 8 mil larger than pad (as desired by me) For copper clearance changeclearsize() works fine.

With the thin-ness though, I'm woried there just can't be any gap behind the LCD, and that it might make it more vulnerable to being damaged. -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!) ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

gEDA-user: Howto make solder mask extend equal for all pads in layout?
Most pads and pins of our footprint libraries have solder mask relief which extends the copper pad to allow some misalignment of solder resist. I have noticed that this extend is very different for different footprints -- from 3 to 10 mil I guess. I think this extend in more a board property than a property of individual footprints, because misalignment of solder resist is a board property of whole board. So I would like to have solder mask extend equal for all my footprints on my board (8 mil I would like). (Yes, I know that there can be good reason to have different solder mask extend for individual footprints, i.e. to build mask which cover adjoining pads (gang solder mask)) Question: How can I make solder mask relief extends equal for all my pads (pins) on the board? I know I can increase/decrease it for individuals pads, but I want an absolute value for all elements. I think it can be done with a script which processes all footprint files before inserting them into the board -- is there a better way or fine script available? For copper clearance situation is similar I guess. Best regards Stefan Salewski ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

What you can do is this: * Enable the mask layer * Select everything that needs the mask set * Use Ctrl-Shift-K to reduce the mask as much as you can for everything selected * :MinMaskGap(Selected,=8,mil) to increase them all to that amount If you're adventurous, you could look up the sources for MinMaskGap() and add a SetMaskGap() that does the same thing, but forces it to a specific value. Should be relatively easy. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Is there something similar for copper clearing of pads/pins in polygons? If you're adventurous, you could look up the sources for MinMaskGap() and add a SetMaskGap() that does the same thing, but forces it to a specific value. Should be relatively easy. At least I will create a feature request for sourceforge bugtracker. Thanks Stefan Salewski ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

changeclearsize(selected,10,mil) I keep forgetting about that, because it reduces the clearance on bigger clearances too, which usually isn't what I want. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
