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 to a

minimum to prevent them from electrical failures and mechanical damages of the devices.

Soldering(Reflow)

(1)Soldering of The SMD Sound Transducers shall conform to the soldering conditions in the individual

G

specifications.
(2)The SMD Sound Transducers are designed for"Reflow Soldering"
(3)In the reflow soldering,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

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

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

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

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 delivery.

C

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 character-

B

istics may be reduced at quality, and/or be degraded in the solderability due to storage under

the poor condition.
