Mechanical keyboard with printed membrane

An electronics assembly of a computer peripheral device, comprising:

• an outer top case;
• a mechanical support layer;
• a first membrane layer coupled with the mechanical support layer, the first membrane layer comprising a first trace that is printed on at least one surface of the first membrane layer;
• a second membrane layer coupled with the mechanical support layer, the second membrane layer comprising a second trace that is printed on at least one surface of the second membrane layer;
• and
• a ground plane positioned on an opposite side of the first and second membrane layers as the outer top case such that the mechanical support layer, the first membrane layer, and the second membrane layer are disposed between the outer top case and the ground plane.

An electronics assembly of a computer peripheral device, comprising:

• an outer top case;
• a mechanical support layer;
• a membrane layer coupled with the mechanical support layer, the membrane layer comprising a printed circuit on at least one surface of the membrane layer, the printed circuit comprising a keyboard matrix;
• a ground plane positioned on an opposite side of the membrane layer as the outer top case such that the mechanical support layer and the membrane layer are disposed between the outer top case and the ground plane;
• and
• a plurality of switches that each extend through the membrane layer and the mechanical support layer.
