Data Transfer Protocol

The IC receives 24-bit data and passes the remaining data to next LED. The 24-bit data consist of green, red and blue data, each with 8-bit width, and are transferred with MSB first.

The transferred data are recognized based on the pulse widths received by the IC. A low bit 0 is represented by a 0.3us high pulse followed by a 0.9us low pulse. A high bit 1 is represented by a 0.9us high pulse followed by a 0.3us low pulse. A low pulse ≧ 200us is used to issue a reset command to the IC to start a new cycle of serial commands.

Precaution for Use 1. The chips should not be used directly in any type of fluid such as water, oil, organic solvent, etc. 2. When the LEDs are illuminating, the maximum ambient temperature should be first considered before operation. 3. LEDs must be stored in a clean environment. A sealed container with a nitrogen atmosphere is necessary if the storage period is over 3 months after shipping. 4. The LEDs must be used within 72hours after unpacked. Unused products must be repacked in an anti-electrostatic package, folded to close any opening and then stored in a dry and cool space. 5. The appearance and specifications of the products may be modified for improvement

without further notice. 6. The LEDs are sensitive to the static electricity and surge. It is strongly recommended to use a grounded wrist band and anti-electrostatic glove when handling the LEDs. If a voltage over the absolute maximum rating is applied to LEDs, it will damage LEDs. Damaged LEDs will show some abnormal characteristics such as remarkable increase of leak current, lower turn-on voltage and getting unlit at low current.

Reel Dimension

Packing

5 or 10 boxes per carton is available depending on shipment quantity.

Page 13

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.

A humidity indicator will be included in the moisture protected anti-static bag prior to shipment.

The packaging sequence is as follows:

Baking Baking before soldering is recommended when the package has been unsealed for 72hours. The conditions are as followings: 1. 60±3℃×(12~24hrs)and<5%RH, taped reel type. 2. 100±3℃×(45min~1hr), bulk type. 3. 130±3℃×(15min~30min), bulk type. 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.

1. If possible, assemble the unit in a clean room or dust-free environment.

Reflow Soldering Recommend soldering paste specifications: 1. Operating temp.: Above 220℃ ,60 sec. 2. Peak temp.:260 ℃Max.,10sec Max. 3. Reflow soldering should not be done more than two times. 4. Never attempt next process until the component is cooled down to room temperature after reflow. 5. 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 ℃.  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 50℃ x 30sec. or <30℃ x 3min  Ultrasonic cleaning: < 15W/ bath; bath volume ≤ 1liter  Curing: 100 ℃ max, <3min

Page 15

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.
