Cautions on Use

1. Moisture-Proof Package

-. The moisture in the SMD package may vaporize and expand during soldering.

-. The moisture can damage the optical characteristics of the LEDs due to the encapsulation.

2. During Storage

UV LED Chips Beads

3. During Usage

-. The LED should avoid direct contact with hazardous materials such as sulfur, chlorine, phthalate, etc.

-. The metal parts on the LED can rust when exposed to corrosive gases. Therefore, exposure to corrosive gases must be avoided during operation and storage.

-. The silver-plated metal parts also can be affected not only by the corrosive gases emitted inside of the end-products but by the gases penetrated from outside environment.

-. Extreme environments such as sudden ambient temperature changes or high humidity that can cause condensation must be avoided.

4. Cleaning

-. Do not use brushes for cleaning or organic solvents (i.e. Acetone, TCE, etc..) for washing as they may damage the resin of the LEDs.

-. Isopropyl Alcohol(IPA) is the recommended solvent for cleaning the LEDs under the following conditions.

Cleaning Condition : IPA, 25℃ max. × 60sec max.

-. Ultrasonic cleaning is not recommended.

-. Pretests should be conducted with the actual cleaning process to validate that the process will not damage the LEDs.

5. Thermal Management

-. The thermal design of the end product must be seriously considered, particularly at the beginning of the system design process.

-. The generation of heat is greatly impacted by the input power, the thermal resistance of the circuit boards and the density of the LED array combined with other components.

6. Static Electricity

-. Wristbands and anti-electrostatic gloves are strongly recommended and all devices, equipment and machinery must be properly grounded when handling the LEDs, which are sensitive against static electricity and surge.

-. Precautions are to be taken against surge voltage to the equipment that mounts the LEDs.

-. Unusual characteristics such as significant increase of current leakage, decrease of turn-on voltage, or non-operation at a low current can occur when the LED is damaged.

7. Electrostatic Discharge (ESD)

- The LEDs are sensitive to static electricity or surge voltage and current.

The Electrostatic Discharge can damage a LED Chip.

Also, It can be affect a reliability belong to the life time of LED package.

When handling LEDs, the following measures against ESD are actively recommended :

1) Please wear a wrist strap, anti-static clothes, foot wear and gloves.

2) Please set up a grounded or anti-static paint floors, a grounded or the ability to surge protection

-workstation equipment and tools.

3) ESD protection- worktable/bench, mat made of a conductive materials.

- An appropriate grounding is required for all devices, equipment, and machinery used in product assembly.

Please apply surge protection after review when designing of commercial products(Curing Module, etc).

- If tools or equipment contain insulating materials such as glass or plastics, the following measures against ESD are strongly recommended :

1) Dissipating static charge with conductive materials

2) Preventing charge generation with moisture

3) Plug in the ionizing blowers(ionizer) for neutralizing the charge

- The customer is advised to check if the LEDs are damaged by ESD when performing the characteristics inspection of the LEDs in the application.

Damage of LED can be detected with a forward voltage checking(measuring) at low current(≤1mA).

- ESD damaged LEDs may have a current flow at a low voltage.

* Failure Criteria : V F < 2.0V at If= 0.5mA.


8. Recommended Circuit

-. The current through each LED must not exceed the absolute maximum rating when designing the circuits.

-. In general, there can be various forward voltages for LEDs. Different forward voltages in parallel via a single resistor can result in different forward currents to each LED, which also can output different

luminous flux values. In the worst case, the currents can exceed the absolute maximum ratings which can stress the LEDs. Matrix circuit with a single resistor for each LED is recommended to avoid the luminous flux fluctuations.

UV Curing LED

Fig.1. Recommended Circuit in Parallel Mode :

Separate resistors must be used for each LED.

Fig.2. Abnormal Circuit :

Avoid this circuits! The current through the LEDs may vary due to the variation in LED forward voltage.


-. The driving circuits must be designed to operate the LEDs by forward bias only.

-. Reverse voltages can damage the zener diode, which can cause the LED to fail.

-. A constant current LED driver is recommended to power the LEDs.

9. Soldering Conditions

-. Reflow soldering is the recommended method for assembling LEDs on a circuit board.

-. LG Innotek does not guarantee the performance of the LEDs assembled by the dip soldering method.UV Ink Curing LED

-. Reflow or hand soldering at the lowest possible temperature is desirable for the LEDs although the recommended soldering conditions are specified in the above diagrams.

-. A rapid cooling process is not recommended for the LEDs from the peak temperature.

-. The silicone encapsulant at the top of the LED package is a soft surface, which can easily be damaged by pressure. Precautions should be taken to avoid strong pressure on the silicone resin when leveraging the pick and place machines.

-. Reflow soldering should not be done more than two times.

10. Soldering Iron

-. The recommended condition is less than 5 seconds at 260℃.

-. The time must be shorter for higher temperatures. (+10℃ → -1sec).

-. The power dissipation of the soldering iron should be lower than 15W and the surface temperature of the device should be controlled at or under 230℃.

11. Eye Safety Guidelines

-. Do not directly look at the light when the LEDs are on.

-. Proceed with caution to avoid the risk of damage to the eyes when examining the LEDs with optical instruments.


12. Manual Handling

-. Use Teflon-type tweezers to grab the base of the LED and do not apply mechanical pressure on the surface of the encapsulant.
