Recommended Method of Storage

1. Over-current-proof

Customer must apply resistors for protection , otherwise slight voltage shift will cause big current change

( Burn out will happen ).

2. Storage

2.1. Do not open moisture proof bag before the products are ready to use.

2.2. Before opening the package, the LEDs should be kept at 30℃ or less and 90%RH or less.

2.3. The LEDs should be used within a year.

2.4. After opening the package, the LEDs should be kept at 30℃ or less and 70%RH or less.

2.5. The LEDs should be used within 168 hours (7 days) after opening the package.

2.6. 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

3.2. Reflow soldering should not be done more than two times.

3.3. When soldering, do not put stress on the LEDs during heating.

3.4. After soldering, do not warp the circuit board.

4. 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.
