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. * Specifications subject to change without notice. Dimensions are in mm ±0.1 unless stated otherwise.
