Notes

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

LED’s characteristics or it may break the LEDs.



Cut the LED leadframes at room temperature. Cutting the leadframes 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.
