I'm trying to create a capacitive sensor that consists of 3 parts, an
inner circle or sensor, an outer circle or shield and a ground plane.
The traces should be made on the opposite side of the board to the pads.
I was hoping to create that as a library component so I can simply drop
a bunch of these on the PCB. There don't seem to be so many design tools
in the library for making pad designs as for making boards.
I've got the answer to how to create the concentric circles from here
PatternAgents: Touch Widgets Library for Eagle
(http://www.patternagents.com/news/2013/11/24/eagle-touch-widgets-library.html)
The sensors are neither through hole connections or SMD pads so how can
I make it so that there's something for the schematic to connect to?
Is it possible to include a via in a package?
