APPLICATIONS

Piezo Film Sheets are available in a different film sizes and
thicknesses. These can be fabricated into simple transducers, or for
use as full size sheets for applications such as speakers.
Metallization options include a compliant silver ink as well as
sputtered metallization. The silver ink is best for applications where
mechanical stress is being applied. Silver ink also lends itself to
custom metallization patterns for easy lead attachment.
The thin, sputtered metallization is more brittle and used where signal
to noise requirements dictate very low mass loading by the
electrodes. Our standard sputtered metallization is 700 A of copper
covered with 100A of nickel, which has good conductivity and is
resistant to oxidation. Other metallizations such as gold are available
on a custom basis with a set up fee. For the sputtered Metallized film,
there is no border.
