The 5 reels may not necessarily have the same lot number or the same bin combinations of Iv, λD and Vf. Each reel has a label identifying its specification; the immediate box consists of a product label as well. 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.

WEITRON http://www.weitron.com.tw 7/9 18-Jan-2011 WT-193NB5 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. The packaging sequence is as follows: PRECAUTIONS 1. 2. Avoid exposure to moisture at all times during transportation or storage. Anti-Static precaution must be taken when handling GaN, InGaN, and AlInGaP products. 3. 4. 5. 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. Avoid operation beyond the limits as specified by the absolute maximum ratings. 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. WEITRON http://www.weitron.com.tw 8/9 18-Jan-2011 WT-193NB5 Reflow Soldering Recommend soldering paste specifications: 1. 2. 3. Operating temp.: Above 220 OC ,60 sec. Peak temp.:260 OCMax.,10sec Max. Never attempt next process until the component is cooled down to room temperature after reflow. 4. The recommended reflow soldering profile (measured on the surface of the LED terminal) is as following: Lead-free Solder Profile 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 Ultrasonic cleaning: < 15W/ bath; bath volume ≤ 1liter Curing: 100 OC max, <3min WEITRON http://www.weitron.com.tw 9/9 18-Jan-2011
