or less and 60%rh or less. 2.3 after opening the package: the led's floor life is 1 year under 30
or less and 60% rh or less. if unused leds remain, it should be stored in moisture proof packages 2.4 if the moisture absorbent material (silica gel) has faded away or the leds have exceeded the storage time, baking treatment should be performed using the following conditions. baking treatment : 60 ? 5
for 24 hours. 3. soldering condition 3.1 pb-free solder temperature profile

for 3 seconds within once in less than the soldering iron capacity 25w. leave two seconds and more intervals, and do soldering of each terminal. be careful because the damage of the product is often started at the time of the hand solder. 5.repairing repair should not be done after the leds have been soldered. when repairing is unavoidable, a double-head soldering iron should be used (as below figure). it should be confirmed beforehand whether the characteristics of the leds will or will not be damaged by repairing.
