High-Flex
formability and conductivity for dynamic flex applications. High-Flex
tapes are constructed of Flectron
with a conductive pressure sensitive adhesive (PSA). This reliable tape
design provides outstanding shielding performance while offering
superior abrasion and corrosion resistance under high dynamic flex
conditions.
The proprietary anti-fray coating of High-Flex
tually eliminates concerns of loose conductive fibers and their poten-
tial to cause board level damage. Other significant advantages over
other fabric and foil shielding tapes include:
High-Flex
0.394" (10 mm) to 1.969" (50 mm) in 0.197" (5 mm) increments
and roll lengths of 65.62' (20 M). Master rolls are available in sizes
up to 1.4 meter widths and 300 meter lengths. For your unique
design requirements, custom die-cut parts are also available.
