In the manual welding time, the welding temperature should be 260 degrees. Welding time should be less than 3 seconds power less than 30 watts. In the case of wave soldering, the welding time should not exceed 5 seconds at 260 degrees. If you use a soldering iron to solder a string of LEDs on a printed circuit board, do not weld both ends of the lamp at the same time.    Welding time to use metal tweezers to hold the lamp foot, which is conducive to the distribution of heat.
   Cleaning: Do not use no specified chemical substances to clean the LED, otherwise it will damage the surface of the LED, if you really need to use alcohol, or fluoride. The time to wash at normal temperature is less than 30 seconds.
