Precautions for Use
1. Over-current prevention:
A series resistor must be used for protection against over-current. Since slight voltage shifts
can cause large current changes and possibly damage the LED.
2. Storage:
2.1. Store the LEDs in the sealed moisture proof bag until ready to use.
2.2. The storage conditions should be below 30°C and 90% RH or less.
2.3. Unused portions of LEDs may be stored in moisture proof packages for up to 1 year if
kept under 30°C and at no more than 60% RH.
2.4. If there is evidence of moisture absorption or if the LEDs have been stored for a long
time, bake the LEDs at 60°C ± 5°C for 24 hours prior to using.
3. Reflow Soldering Conditions:
3.1. Pb-free solder temperature profile (see figure):
3.2. Reflow solder no more than two times and must include time interval for the board to
cool.
3.3. When soldering, do not put stress on the LEDs during heating.
3.4. After soldering, do not warp the circuit board.
4. Hand Soldering:
Use a low wattage soldering iron (below 25 watts) with a tip temperature no more than
350°C for 3 sec or less on one terminal. Wait at least two seconds before soldering the next
terminal to avoid overheating the LED and damaging it.
5. Avoid reworking a soldered LED. It is best to simply replace it with a new part.
