Precautions
------------------------------------------------------------------------------------------------------------------------------------
A. Storage
It can be stored for 3 months under conditions of Temperature 23+/-5 and humidity 30-65%。During
storage, there must not be any damage to the sealed bag, and if opened once, do not store again. After the
package is opened, the products should be used within one week under the same temperature and humidity.
B. Cleaning
Do not use any unidentified chemical to clean LEDS, it could damage or crack the LED epoxy surface.
If necessary, soak LED in alcohol for a time not exceeding one minute in normal temperature.
C. Lead Frames Shaping & Trimming
1. The shaping should be done underneath the wedge point. No pressure should be exerted to the epoxy
shell of the LED during shaping.
2. Shaping of the leads should be done before soldering.
3. Lead trimming should only be done at normal temperature.
D. Soldering
1. When soldering, the soldering iron needs to be at least 1.6mm away from the epoxy edge. Do not
apply any pressure to the epoxy encapsulation or the lead frame during the soldering process.
2. When reflow soldering or wave soldering, please solder once for less than 5 seconds at a maximum
temperature of 265°C. During the soldering process, if the temperature or timing is not controlled within
limits, it would cause the epoxy to deform or cause the die or wires within the LED to be damaged.
3. When using soldering iron, please solder once for less than 5 seconds at a maximum temperature of
350°C+10°C. When soldering a row of LED on a PCB, please do not solder both leads of a LED in sequence.
(Solder the positive lead at first, then the negative leads)
4. Do not dip the epoxy encapsulation part of LED into any soldering paste liquid.
5. After soldering, do not adjust the location of the LED anymore.
