5.1 Mounting and Capture Guidelines
Achieving an optimal mounting design requires that consideration be given to the following
guidelines:
5.1.1 Capture
Design of the enclosure used to capture the VersaPad module can follow either a top
or bottom installation method. Pressure sensitive gaskets or adhesives may be used to
support and protect the VersaPad. Tolerances of gaskets, bezels, etc. should be
chosen to avoid contact with the sensor active area under all conditions.
5.1.2 Protection of the Spacer edge
It is possible that long term wear can emboss the touchpad sensor near the spacer
edge. To avoid this, the top case or an additional bezel should be used to overhang the
spacer. A small vertical gap is necessary to avoid touching the sensor. Size and
position tolerance should be chosen to overlap the spacer under all conditions. See
figure 5.
