Soldering(Reflow)
(1)Soldering of The SMD Sound Transducers shall conform to the soldering conditions in
the individual specifications.
(2)The SMD Sound Transducers are designed for "Reflow Soldering" under the
recommended solder profile
.
(3)SMD Sound Transducers which during the reflow soldering process are exposed to too
high soldering temperatures and/or too large temperature gradient such as rapid heating or
cooling may lead to electrical failures and mechanical damages of the devices.
