GENERAL INFORMATION

HOW TO USE LED

FORMING:

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:

Soldering Bath ---2605 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 .
CLEANING:

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
R= WHERE:
Vs=Source Voltage
VF=Forward Voltage
If=Recommended Current of LED (10-20mA)
BRIGHTNESS:

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 .

APPLICATION NOTES

Cleaning Avoid using any unspecified chemical solvent to clean LED . For example, Trichloroethylene, Chlorosen, Acetone, and Diflon S3MC. Any cleaning method can only be taken under normal temperature in one minute or less if it is required. Alcohol is the one recommended for cleaning.
