Re: gEDA-user: Quick and Easy solder mask creation
> Where is the paste mask set? Is it computed from the pad information?
PCB doesn't currently support a separate paste mask definition. It is
defined as being exactly the same as the pad size/shape. What I do is
post-process the .pcb file with a perl script, to produce a new one
with adjusted pad sizes, which is used only to produce the paste mask.
PCB does have solder mask settings, but only as a "this much
bigger/smaller than the pad" dimension. That means, to do a grid you
have to use multiple overlapping pads with a mask smaller than the
pad, like this:
Element["" "" "" "" 35000 57500 0 0 0 100 ""]
(
Pad[-11250 -41250 -11250 -41250 7500 2000 5500 "" "4" "square"]
Pad[-3750 -41250 -3750 -41250 7500 2000 5500 "" "4" "square"]
Pad[3750 -41250 3750 -41250 7500 2000 5500 "" "4" "square,edge2"]
Pad[11250 -41250 11250 -41250 7500 2000 5500 "" "4" "square,edge2"]
Pad[11250 -33750 11250 -33750 7500 2000 5500 "" "4" "square,edge2"]
Pad[3750 -33750 3750 -33750 7500 2000 5500 "" "4" "square,edge2"]

Pad[-11250 -33750 -11250 -33750 7500 2000 5500 "" "4" "square"]
