Reflow Soldering Characteristics Caution 1. Reflow soldering is recommended not to be done more than two times. In the case of more than 24 hours passed soldering after first, LEDs will be damaged. 2. Repairs should not be done after the LEDs have been soldered. When repair is unavoidable, suitable tools must be used. 3. Die slug is to be soldered. 4. When soldering, do not put stress on the LEDs during heating. 5. After soldering, do not warp the circuit board.! Notes on Refond EMC Series soldering: 1. Recommend to use reflow machine. 2. Recommend to use heating plate soldering. 3. Manual soldering is not recommended.! Notes on reflow process: 1. To confirm whether the actual temperature curve in the reflow soldering conditions comply with recommended conditions. LEDs are guaranteed for one time reflow. 2. During reflow process do not apply force on LED active area. 3. After reflow process, PCB board should be cooled down before packing or storage.! 11
