Precaution in use 9.1 Soldering Conditions When soldering SMD LED , Heat may affect the electrical and optical characteristics of the LEDs. In soldering, do not stress the lead frame and the resin part under the high temperature. The epoxy part should be protected from mechanical stress or vibration until the SMD LEDs return to room temperature after soldering. ▪ Preliminary heating to be at 150℃ max. for 180 Seconds max. ▪ Soldering heat to be at 260℃ max. for 5 sec. Max. ▪ For manual Soldering is not more than 3 sec @MAX 350 ℃, under soldering iron <Recommendable soldering pattern> 120~180sec.Max 9.2 Storage Use with 7days after opening packing. Store in 10 to 30 ℃ SMD LED lead frames are plated silver. The silver surface may be affected by environment which contain corrosive gases and so on. Please avoid condition which may cause the SMD LED to corroded, tarnish or discolor. 9.3 Static Electricity Static electricity or surge voltage damages the SMD LEDs. It is recommended that a wrist band or an anti-electrostatic glove be used when handling the LEDs. A tip soldering iron is requested to be grounded. An ionizer should also be installed where risk of static. All devices, equipment and machinery must be properly grounded (via 1MΩ). It is recommended that measures be taken against surge voltage to the equipment that mounts the SMD LEDs. 9.4 Cleaning Isopropyl Alcohol or Ethylene Alcohol is recommended in 5 minutes at room temperature. Don’t use unspecified chemical may cause crack or haze on the surface of the epoxy resin. Before cleaning, a pre-test should be done to confirm whether any damage to the SMD LED will occur. Freon solvents should not be used to clean the LEDs because of worldwide regulations. IWS- 164 –WXWF-S2 Version of 3. 2 PAGE : 8 / 11 Topview 1608 White LEDs IWS-164-WXWF-S2 10.

ATTENTION : Electric Static Discharge (ESD) Protection The symbol shown on the page herein to introduce ‘Electro-Optical Characteristics’. ESD protection for GaP and AlGaAs is based chips is still Necessary even though they are safe in low static-electric discharge. Material in AlInGaP, GaP, or/and InGaN based chips are STATIC SENSITIVE devices. ESD protection has to considered and taken in the initial design stage. If manual work/process is needed, please ensure the device is well protective From ESD during all the process. LED’s ESD Level is ‘Class 1’ and The range of Forward Voltage is 1V ~ 1999V. After opening the package, the LED’s should be kept at 30℃, 70%RH or less. The LEDs must be dip soldered within seven days(168 hours) after opening the moisture-proof packing. It is better not to use different rank LEDs. If use mixed rank, could not attain your object for highest quality of products.
