4.Surface Mounting Condition

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 minimum to preven them from electrical failures and mechanical damages of the

G

F

devices.
Soldering(Reflow)
(1)Solderings of The SMD Sound Transducers shall conform to the soldering conditions in

the individual specifications.
(2)The SMD Sound Transducers are designed for"Reflow Solderings"
(3)In the reflow solderings,too high soldering temperatures and too large tempearture
gradient such as rapid heating or cooling may cause electrical failures and mechanical
damages of the devices.

Follwing soldering conditions are recommend;Refer to Fig.1

6.2 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.

6.3 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.

6.4 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.
