Please do not form the LED after soldering .If forming id necessary ,it must be done before soldering .
Any unsuitable stress applied to the epoxy may break bonding wires in LED.
Soldering Bath ---260℃±5 ℃ within 5 seconds: Soldering Iron-Under 30W within 5 seconds.(1.6mm from epoxy body)
Do not apply any force of mechanical stress onto the leads or epoxy body during soldering heat is remained.
If soldering one line of LED on a P.C . board by using a soldering iron ,don t solder both the leads of the LED at same time .
Use Alcohol ,Freon TE or Chlorosen to clean LED at normal temperature for less than l minute .
Do not use unspecified chemical liquid because it may cause crack or haze on the epoxy body.
·PREVENTING OVER CURRENT :
In order to operate LED in stable condition , please put protective resistors in series.
Resistor value can be determined by the formula
If=Recommended Current of LED (10-20mA)
For the purpose of obtaining uniform brightness, LED shall be same current.
It is useful for uniform brightness if you use larger source voltage and protective resistor .
