Abstract
An apparatus may include a stack of layers, the stack including a sensor layer containing a set of electrodes and a suction opening defined through the sensor layer, and a capacitance reference surface adjacent to the sensor layer.
Claims20
A capacitance module apparatus, comprising:
- a substrate containing a set of capacitance-sensing electrodes on an electrode layer forming a capacitance sensor area on a first side of the substrate;
- an adhesive applied to electrode layer and spread throughout the capacitance sensor area;
- a suction opening defined through the substrate in the capacitance sensor area between the capacitance-sensing electrodes on the first side of the substrate;
- wherein air and/or adhesive are suctioned through the suction opening during vacuum adhesion between the substrate and a reference capacitance surface.

An apparatus, comprising:
- a stack of layers, the stack including:
- a sensor layer containing a set of electrodes where the electrodes define a capacitance sensor area on a first side of the substrate;
- a suction opening defined through the sensor layer and located between the electrodes on the first side of the substrate;
- a capacitance reference surface adjacent to the sensor layer;
- an adhesive between the sensor layer and the capacitance reference surface where the adhesive is applied directly to the capacitance sensor area;
- wherein a portion of the adhesive has been suctioned through the suction opening during vacuum adhesion between the substrate and a reference capacitance surface.

A method for adhering a capacitive sensor to a capacitance reference surface, comprising:
- applying an adhesive to one side of either the capacitive sensor or the capacitance reference surface, such that the adhesive is disposed between the capacitive sensor and the capacitance reference surface;
- moving the capacitive sensor and capacitance reference surface towards each other with the adhesive between them;
- and
- applying a suction force through at least one suction opening defined in the capacitance reference surface when moving the capacitance sensor and the capacitance reference surface towards each other;
- wherein air is suctioned through the at least one suction opening in the capacitive sensor;
- wherein the suctioning of air through the at least one suction opening has the function of reducing the amount of air bubbles between the capacitive sensor and the capacitive reference surface.
