Re: gEDA-user: Suggestions for using a capacitive sensor IC

[DJ Delorie <dj@xxxxxxxxxxx>]

If you just want a round electrode, define your footprint as a single
SMT pad, rounded, with the same width and height.  This gives you a
big circle of copper.  You can set the mask size to 0 to have it
covered (you don't need electrical connectivity).

If you're having the boards assembled elsewhere, you'll want to write
a script or something to search for those pads and omit them from the
paste output.

For other shapes, it's probably easiest to create them while laying
out the board, using some tiny SMT pad as the "official" pad.  Or you
can build up a footprint from a collection of rounded and rectangular
pads, just give them all the same pin number.
