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

devices.

G

Soldering(Reflow)

G

(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

6.1 The products mustn't be washed

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

and shall not be used in whole or in part without its written content

the following conditions:
Temperature: -10 to + 40 C Humidity: 15 to 85% R.H.

This print and information there in are proprietary to Bestar Electronics Industry Co., Ltd.

6.3 Expire Date on Storage

Expire date (Shelf life) of the products is six months after deliveried under the conditions of a

C

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.

B

(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.
