４．SOLDERING（Sn-3Ag-0.5Cu）

　(1) Please make soldering rapidly under the following temperature and time conditions.

　(2) Please avoid stress to LED lamp during soldering.

　(3) In case of double peak flow soldering, the temperature gap during 1st and 2nd soldering to be

　　less than 100 degree C.

＜Recommendable soldering conditions＞

SOLDERINGTEMP OPERATION TIME

Remarks

Pre-heat Max. 100℃ 60sec Max.

－

Soldering Dip Soldering Bath Max. 265℃

In case of double peak flow soldering, the operation

5sec Max. time is counted from the beginning of 1st peak

to the end of 2nd peak.

Soldering Iron

Max. 400℃ 3sec Max. The iron should not touch the LEDʼs body.

５．CLEANING

　In case of cleaning, some solvents may cause damage of resin or cause non-lighting failure,

　so please check the solvent before actual use.

　The recommendable cleaning solvent is alcoholic one such as isopropyl alcohol.

＜RECOMMENDABLE CLEANING CONDITIONS＞

METHOD

CONDITIONS

Cleaning by solvent

Temperature of solvent ：Max. 45℃

■ATTENTION ON STORAGING

　Storage in dry box is most desirable, but if it is not possible, we recommend following conditions.

＜RECOMMENDABLE STORAGE CONDITIONS＞

ARTICLE Temperature Humidity Expiration Date

CONDITIONS 5〜30℃ Max.60%RH Within 1 year

Poor storage conditions may cause some failure as bellow.

　(1) Lead pins may corrode if it is stored in the environment of high temperature and humidity

　　and lead to defective soldering.

　(2) In case of soldering after LEDʼs body absorb moisture highly, destruction or inferiority of

　　luminous intensity may occur.
