4. Product Handling
Never remove the touch screen from its package by gripping and pulling the flat cable. This may break the cable.
Handle the product with gloves to avoid leaving fingerprints or smudges. The transparency of the touch screen is critical.
Once removed from the original package, touch screens are not to be stacked. The edges may cause scratching.
Do not place heavy objects on the touch screen.
Prevent assembly tools from coming into contact with the touch screen.
Whenever possible, use plastic tools. Do not apply undue stress to the cable area (this is the most fragile section).
Blow any contaminants from the surface with a filtered de-ionized air source before cleaning with a soft, lint-free cloth dampened with isopropyl alcohol. Ensure that there are no contaminants in the cloth.
Prevent any liquids from coming into contact with the edges of the touch screen.

5. Product Inspection – Size and Types
Viewing Area Anomalies
All diameters refer to the smallest circle that will totally contain the anomaly.
A maximum of 5 anomalies within specification are allowed per touch screen.
Artifacts measuring less than inches are not counted as anomalies.
All Measurements Are In Inches

8. Product Cleaning
Typically, an isopropyl alcohol and water solution ratio of 50:50 is the best cleaning agent for your touch screen. You can also use straight isopropyl alcohol. In addition, 3M Touch Screen Cleaner CL680 has been tested and approved for this use. Be sure to follow solvent manufacturer's precautions and directions for use when using any solvents.
It is important to avoid using any corrosive chemicals on the touch screen. Do not use any vinegar‑based solutions.
Always dampen the cloth and then clean the screen. Be sure to spray the cleaning liquid onto the cloth, not the screen, so that drips do not seep inside the display or stain the bezel.
Apply the cleaner with a soft, lint-free cloth. Avoid using gritty cloths.
Always handle the touch screen with care. Do not pull on or stress flex tail

9. Prepare the Touch Screen
Strips of high-density foam mounting tape (3M Product Numbers 4956, 4956F, or 4979F) with adhesive on both sides should be used to attach the touch screen to the LCD metal frame. These strips should not form a full seal – allow for ventilation (1-2 mm gaps) at the corners as shown above. Because new LCDs run significantly hotter than their predecessors, you should allow air to escape to avoid damaging the LCD with temperature and pressure equalization issues.
Leave small space (1-2 mm) to enable ventilation

10. Mounting the Touch Screen
The touch screen must be mounted such that the spacing between the touch screen and LCD does not vary due to compression or expansion from touch forces or temperature changes. For optimal performance, we strongly recommend using 3M brand 4956, 4956F, or 4979F tape for this purpose. Failure to mount the touch screen in this fashion may result in reduced accuracy.
Tape extending beyond the touch screen edge may cause excessive stress on the tail connection. Apply the tape to the touch screen surface, rather then the LCD, to ensure proper alignment. DON’T: Mounting tape should not extend beyond the touch screen
DON’T: Mounting tape should not extend beyond the touch screen.
DO:
Mounting tape should align with touch screen.

12. Routing the Touch Screen Cable
To minimize the risk of electromagnetic interference, never run the touch screen tail near or over the LCD backlight inverter. Although the tail is shielded, the noise generated by an inverter is broadband and can contain frequencies close to the signal frequency.
The touch screen tail is not a handle. Never pick your touch screen up by the tail. It is an electrical connection and is not designed for high stress.
Do not place constant stress on the tail during handling or integration. Do not expose the tail to mechanical stresses because of the integration design. Provide adequate slack to ensure there is no straining on the tail. Avoid lateral pulls that may overstress the outermost electrical contacts on the glass.
Avoid creasing the tail within 0.5 inch (1.27 cm) of the strain relief. A soft bend is acceptable.
Avoid creasing the tail within 0.5 inch (1.27 cm) of the strain relief. A soft bend is acceptable.

13. Routing the Touch Screen Cable (continued)
Always design your touch screen integration with the flex tail exiting from the top or sides of the display. Never design tail exits from the bottom as spills could accumulate in the tail attachment area and cause electrical shorting.
The touch screen tail is designed to be flexible, and it may be creased once in a single direction, in multiple locations along the tail and then secured in position with a light adhesive tape. Avoid angular creases (45°) to the tail directly in the area of the bond and tape strain relief.
The touch screen tail should not move freely after assembly. Apply tape or another light adhesive to secure the tail in a manner that does not apply stress to the tail.
Apply tape or other insulating material to sharp edges to protect the tail. Route the cable away from sharp edges whenever possible. If this cannot be avoided, secure the tail so it does not move.
