Cleaning, Handling Precautions, and Storage, Anti-static protection

All products are cleaned thoroughly before shipping, which means that in most normal cases there is no need to clean before use. In cases where a minimal amount of dirt and dust particles have come in to contact with the product, it is advised to follow these steps:

1. Handle in a clean environment.

2. Try swabbing gently using lint-free swabs.

3. If needed, the use of lint-free swab and IPA (isopropyl alcohol) can be used to gently remove dirt from the surface. Do not use other solvents as they may directly react with LED emitting region.

4. Do not use ultrasonic cleaning that the LED will be damaged.

5. Do not use ultrasonic cleaning as this may damage the LED.


If it is necessary to handle the product, it is recommended to use anti-static tweezers. However, do not touch the lens with tweezers or fingers.

1.  Do not touch the lighting emitting surface (LES) in any circumstance.

2. Users should wear the anti-static gloves or an anti-static wrist band.

3. When handling the SMD, users should use anti-static tweezers.

(Especially, the sharpened-tips of the tweezers would have high possibility of giving a physical defect to the SMD)

1.  Do not open the moisture-barrier packaging (MBP) before the products are ready to be used.

2.  Before opening the MBP: To avoid moisture penetration, we recommend storing in a dry box with a desiccant. The recommended storage temperature range is 5℃ to 30℃ with a maximum humidity of RH60%.

3.  After opening the MBP: If unused SMDs remain, we recommend storing in a moisture proof bag or in the original packaging bag with a moisture absorbent material. There is a limited exposure time before damage to the LED may occur during the soldering operation. The table listed below specifies the maximum exposure time in days depending on temperature and humidity conditions. If the moisture absorbent material (silica gel) has faded away or the LEDs have an exposure time longer than specified maximums, baking treatment should be performed at 60℃ for 24 hours.

Anti-static protection

1. LED package is extremely sensitive to static electricity. It’s recommended that anti-electrostatic glove and wrist band is necessary when handling the SMDs. All devices are also be grounded properly as well.

2. Protection devices should be designed for SMDs driving circuit.

Soldering precautions, Conditions and Process

1. Over-current-proof

Customer must apply resistors for protection; otherwise a slight voltage shift will cause large current change (Burn out will occur).

2. Soldering Conditions

2.1 Pb-free solder temperature profile:

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

2.3 When soldering, do not put stress on the LEDs during heating.

2.4 After soldering, do not warp the circuit board.

3. Soldering Iron

The soldering iron temperature should be less than 350℃ and should only contact each terminal for 3 seconds at once. The soldering iron capacity should be 25W. After first contact, wait for two seconds before further contact intervals of each terminal. Be careful because hand soldering is usually the cause of damage to the product.

4. Repairing

Repair should not be performed after the LEDs have been soldered. When repairing is unavoidable, a double-head soldering iron should be used (as below figure). It should be confirmed beforehand whether the characteristics of the LEDs will or will not be damaged by repairing.
