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.

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.

Although the recommended soldering conditions are specified in the above table, dip or
handsoldering at the lowest possible temperature is desirable for the LEDs.
Wave soldering parameter must be set and maintain according to recommended
temperature and dwell time in the solder wave.
4. Cleaning
When necessary, cleaning should occur only with isopropyl alcohol at room temperature
for a duration of no more than one minute. Dry at room temperature before use.
Do not clean the LEDs by the ultrasonic. When it is absolutely necessary, the influence of
ultrasonic cleaning on the LEDs depends on factors such as ultrasonic power and the
assembled condition. Ultrasonic cleaning shall be pre-qualified to ensure this will not
cause damage to the LED.
5. Heat Management
Heat management of LEDs must be taken into consideration during the design stage of
LED application. The current should be de-rated appropriately by referring to the de-rating
curve found in each product specification.
The temperature surrounding the LED in the application should be controlled. Please refer
to the data sheet de-rating curve.
6. ESD (Electrostatic Discharge)
Electrostatic discharge (ESD) or surge current (EOS) can damage LEDs.
An ESD wrist strap, ESD shoe strap or antistatic gloves must be worn whenever handling
LEDs.
All devices, equipment and machinery must be properly grounded.
Use ion blower to neutralize the static charge which might have built up on surface of the
LEDs plastic lens as a result of friction between LEDs during storage and handing.
7. Other
Above specification may be changed without notice. EVERLIGHT will reserve authority
on material change for above specification.
