Mounting Tape to the Display
The 3M™ MicroTouch™ DST2270DX sensor comes with 3M 5962 and 5925 VHB™
acrylic foam mounting tape already applied to the surface that attaches to your display.
This 0.2 inch (5.08 mm) wide mounting foam tape was selected for its mechanical and
thermal properties to help ensure your sensor integration is successful.
Together, the mounting tape and the bezel-sealing gasket serve to mechanically decouple
the sensor from potential interference.
This mounting tape intentionally stops about an inch from the piezos to keep from
interfering with the electrical components on the corners.
Note
: For ease of maintenance, put a border of polyimide tape around the perimeter of
the LCD. Then adhere the 3M VHB mounting tape to the polyimide tape. The polyimide
tape will enable you to easily remove the VHB tape if the need arises.
Strips of thin, foam tape (VHB 5962 and VHB 5925) with adhesive on both sides are
already attached to the sensor. Use these strips to attach the sensor to the display metal
frame. The sensor must be mounted such that the spacing between the sensor and display
does not vary due to compression or expansion from touch forces or temperature
changes. Failure to mount the sensor in this fashion may result in reduced functionality.
