KEYBOARD ASSEMBLIES HAVING REDUCED THICKNESS AND METHOD OF FORMING KEYBOARD ASSEMBLIES

摘要

Keyboard assemblies having reduced thicknesses and methods of forming the same. A keyboard assembly may include a printed circuit board (PCB) and a single membrane sheet adhered directly to the PCB. The single membrane sheet may substantially cover the PCB. The keyboard assembly may also include a group of dome switches coupled directly to the single membrane sheet. Another keyboard assembly may include a group of conductive pads and a group of membrane pads. Each of the group of membrane pads may be adhered directly to a corresponding one of the group of conductive pads. The keyboard assembly may also include a group of dome switches coupled directly to the membrane pads. Each of the group of dome switches may be coupled directly to a corresponding one of the group of membrane pads.
