ATTENTION: Electric Static Discharge (ESD) protection  
The symbol shown on the page herein to introduce ‘Electro-Optical Characteristics’. ESD  
protection for GaP and AlGaAs based chips is still necessary even though they are safe in  
low static-electric discharge. Parts built with AlInGaP, GaN, or/and InGaN based chips are  
STATIC SENSITIVE devices. ESD protection has to considered and taken in the initial design stage.  
If manual work/process is needed, please ensure the device is well protected from ESD during all the  
process.

Packing  
5 boxes per carton is available depending on shipment quantity.  
Dry Pack  
All SMD optical devices are MOISTURE SENSITIVE. Avoid exposure to moisture at all times  
during transportation or storage. Every reel is packaged in a moisture protected anti-static bag.  
Each bag is properly sealed prior to shipment.  
Upon request, a humidity indicator will be included in the moisture protected anti-static bag  
prior to shipment.  
Storage  
It‟s recommended to store the products in the following conditions:  
Humidity: 60 %RH Max.  
Temperature: 5℃ ~30℃ (41℉~86℉)

The packaging sequence is as follows  
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.

Soldering Pattern  
The dimensions of the recommended soldering pattern may not meet every user. Please  
confirm and study first before designing the soldering pattern in order to obtain the best  
performance of soldering. Recommended soldering pattern is listed below:  
Unit: mm  
Reflow Soldering  
Recommend soldering paste specifications:  
1. Operating temp.: Above 220 OC ,60sec  
2. Peak temp.:260 OCMax.,10sec Max.  
3. Never take next process until the component is cooled down to room temperature after  
reflow.  
4. The recommended reflow soldering profile (measuring on the surface of the LED terminal)  
is following:

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.  
Electric-static may cause damage to the component. Please ensure that the equipment  
is properly grounded. Use of an ionizer fan is recommended.
