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.

Max. 400ºC 3sec Max. The iron should not touch the LED’s 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.

6. RECOMMENDABLE ROUND PATTERN
Round pattern depends on the material PCB, density and circuit arrangement.
Our recommendation is as follow :

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

Max.60%RH
Expiration Date
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 LED’s body absorb moisture highly, destruction or inferiority of luminous intensity
may occur.
