In automated mounting of The SMD Sound Transducers on printed circuit boards, any
bending, expanding and pulling forces or shocks against the SMD Sound Transducers shall
be kept to a minimum to prevent them from electrical failures and mechanical damages of
the devices
G
Soldering(Reflow)
G
(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
F
(3)SMD Sound Transducers which during the reflow soldering process are exposed to too
F
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.

7.1 The products mustn't be washed
7.2 Storage Condition
The products should be stored in the room ,where the temperature/humidity is stable. And
avoid such places where there are large temperature changes. Please store the products at
the following conditions:
Temperature: -10 to + 40 C Humidity: 15 to 85% R.H.
7.3 Expire Date on Storage
Expire date (Shelf life) of the products is six months after deliveried under the conditions of a
sealed and an unopened package. Please use the products within six months after deliveried.
If you store the products for a long time (more than six months), use carefully because the
products may be degraded in the solderability and/or rusty.Please confirm solderability and
characteristics for the products regularly.
7.4 Notice on Product Storage
(1) Please do not store the products in a chemical atmosphere (Acids, Alkali, Bases, Organic
gas, Sulfides and so on), because the characteristics may be reduced at quality, and/or be degraded in the solderability due to the storage in a chemical atmosphere.
(2) Please use the products immediately after the package is opened, because the characteristics may be reduced at quality, and/or be degraded in the solderability due to storage under
the poor condition.
