Abstract
A keyboard having an array of non-planar keys and a method for manufacturing such a keyboard is provided. In one embodiment, the non-planar array is a double-convex array. Electrical connection along the keys and/or from the keys to associated electronics is provided by way of a circuit board. The circuit board has a geometry and flexibility which permits the circuit board to conform to a shape which is non-planar along two non-parallel axes. In one embodiment, the circuit board can be configured in a double-concave shape. The circuit board includes one or more slots defining two or more projections. These projections can be placed in a configured non-coplanar configuration along a first axis and the circuit board can be flexed to a non-planar configuration along a second non-parallel axis.
