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.
