Abstract
A touch-sensor device has a first board coupled to a second board. The first board has a first substrate with a first plurality of sensing elements and a second plurality of sensing elements. A first plurality of conductive trace connects the first plurality of sensing elements along a first axis. A dielectric material is formed on the first plurality of sensing elements and on the first plurality of conductive traces. The second board has a second substrate and a second plurality of conductive traces that connects the second plurality of sensing elements along a second axis.
