ATTENTION: Electrostatic Discharge (ESD) protection
The symbol to the left denotes that ESD precaution is needed. ESD protection for
GaP and AlGaAs based chips is necessary even though they are relatively safe in
the presence of low static-electric discharge. Parts built with AlInGaP, GaN, or/and
InGaN based chips are STATIC SENSITIVE devices. ESD precaution must be taken during
design and assembly.
If manual work or processing is needed, please ensure the device is adequately protected
from ESD during the process.

Precautions
1. Avoid exposure to moisture at all times during transportation or storage.
2. Anti-Static precaution must be taken when handling GaN, InGaN, and AlInGaP products.
3. It is suggested to connect the unit with a current limiting resistor of the proper size. Avoid
applying a reverse voltage beyond the specified limit.
4. Avoid operation beyond the limits as specified by the absolute maximum ratings.
5. Avoid direct contact with the surface through which the LED emits light.
6. If possible, assemble the unit in a clean room or dust-free environment.
Reworking
• Rework should be completed within 5 seconds under 260 OC.
• The iron tip must not come in contact with the copper foil.
• Twin-head type is preferred.
Cleaning
Following are cleaning procedures after soldering:
• An alcohol-based solvent such as isopropyl alcohol (IPA) is recommended.
• Temperature x Time should be 50oC x 30sec. or <30oC x 3min
• Ultra sonic cleaning: < 15W/ bath; bath volume ≤ 1liter
• Curing: 100 OC max, <3min
Cautions of Pick and Place
• Avoid stress on the resin at elevated temperature.
• Avoid rubbing or scraping the resin by any object.
• Electro-static may cause damage to the component. Please ensure that the equipment
is properly grounded. Use of an ionizer fan is recommended.
