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 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 conditions:

Hand Soldering DIP Soldering

Temp. at tip of iron 300℃ Max. (30W Max.) Preheat temp. 100℃ Max. (60 sec Max.)

Soldering time 3 sec Max. Bath temp. & time 260 Max., 5 sec Max

Distance 3mm Min.(From solder

joint to epoxy bulb)

Distance 3mm Min. (From solder

joint to epoxy bulb)

 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 hand soldering 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)

 The products are sensitive to static electricity or surge voltage. ESD can damage a die and its reliability.

When handling the products, the following measures against electrostatic discharge are strongly

recommended:

Eliminating the charge

Grounded wrist strap, ESD footwear, clothes, and floors

Grounded workstation equipment and tools

ESD table/shelf mat made of conductive materials

 Proper grounding is required for all devices, equipment, and machinery used in product assembly.

Surge protection should be considered when designing of commercial products.

 If tools or equipment contain insulating materials such as glass or plastic,

the following measures against electrostatic discharge are strongly recommended:

Dissipating static charge with conductive materials

Preventing charge generation with moisture

Neutralizing the charge with ionizers

7. Directions for use

 The LEDs should be operated with forward bias. The driving circuit must be designed so that the LEDs are not subjected

to forward or reverse voltage while it is off. If reverse voltage is continuously applied to the LEDs, it may cause migration

resulting in LED damage.
