General Converting, Assembly, and Handling Recommendations
During converting operations, both the front and rear protective liners should remain on the film.
Die cutting is the recommended form of converting and will result in the cleanest edges, although shear
cutting and laser cutting may also be acceptable. Whatever method utilized, you should insure that the part
has clean, crisp edges without any raggedness or other damage.
The part should be precisely cut to provide a close fit in the cavity, yet not so close to experience binding or
warping problems from thermal expansion.
The part should be left free-floating in the cavity to avoid warping or buckling. If necessary, the part may be
tacked down along one edge or two adjacent corners with a double-coated tape, such as Scotch
Designs incorporating mounting tabs, or holes mated to mounting pins, are also popular.
Remove both protective liners, if the film has them, by tacking near an edge or corner with a piece of
aggressive tape and pull gently.
If two pieces of 3M Vikuiti Prismatic Film (BEF II, BEF III, TBEF) are to be incorporated, they should be
converted with the grooves of the prism structure of the first sheet at a 90-degree angle to the grooves
direction of the second sheet.
Be aware that handling any polymer film can generate electrostatic charges, which can attract dust
and debris.
Remove any loose debris from the film by using compressed air.
Avoid fingerprints and debris by wearing clean latex gloves and holding the product at the edges.
Keep the area very clean to lessen the likelihood of debris contamination. Maintaining class 1000 clean room
conditions is recommended.
Using anti-static measures, such as ionized air blowers, whenever possible is recommended.
As always, protect the film, especially the edges, from any undue shock or stress.
S t o r a g e
Material should be stored in its original packaging, laying in a horizontal orientation, away from direct sunlight.
Heavy objects should not be piled on top of it to avoid damaging the product. Ambient temperature and
humidity should be controlled to 10 – 30ºC at 50 +/- 20% R.H.
