1.    Lead Forming
 
During lead formation, the leads should be bent at a point at least 3mm from the base of the epoxy bulb.
 
Lead forming should be done before soldering.
 
Avoid stressing the LED package during leads forming. The stress to the base may damage the LEDs characteristics or it
may break the LEDs.
 
Cut the LED lead frames at room temperature. Cutting the lead frames at high temperatures may cause failure of the LEDs.
 
When mounting the LEDs onto a PCB, the PCB holes must be aligned exactly with the lead position of the LED. If the LEDs
are mounted with stress at the leads, it causes deterioration of the epoxy resin and this will degrade the LEDs.
2.    Storage
 
The LEDs should be stored at 30?C or less and 70%RH or less after being shipped from Everlight and the storage life limits
are 3 months. If the LEDs are stored for 3 months or more, they can be stored for a year in a sealed container with a
nitrogen atmosphere and moisture absorbent material.
 
Please avoid rapid transitions in ambient temperature, especially, in high humidity environments where condensation can
occur.
3.    Soldering
 
Careful attention should be paid during soldering. When soldering, leave more then 3mm from solder joint to epoxy bulb,
and soldering beyond the base of the tie bar is recommended.

Recommended soldering profile
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Avoiding applying any stress to the lead frame while the LEDs are at high temperature particularly when soldering.
 
Dip and hand soldering should not be done more than one time
 
 
After soldering the LEDs, the epoxy bulb should be protected from mechanical shock or vibration until the LEDs return to
room temperature.
 
A rapid-rate process is not recommended for cooling the LEDs down from the peak temperature.
