Precaution in use 9.1 Soldering Conditions When soldering Power SMD, 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 silicone part should be protected from mechanical stress or vibration until the Power SMD return to room temperature after soldering. ▪ Preliminary heating to be at 160 ℃ max. for 120 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 < Lead Free > 260℃ Max. 5sec. Max. <Recommendable soldering pattern> <Unit: mm> 1~5 ℃/sec Pre-heating 140~160℃ 1~5 ℃/sec 120sec.Max. 60sec.Max. Above 220℃ 9.2 Storage Before opening the package, the LEDs should be kept at 30℃ or less and 70%RH or less. The LEDs should be used within a year. After opening the package, the LEDs should be kept at 30℃ or less and 30%RH or less. The LEDs should be used within 168 hours (7 day) after opening the package. If the moisture absorbent material (silicagel) has faded away or the LED have exceeded the storage time, baking treatment should be performed using the following conditions. Baking treatment: 60℃±5 for 72 hours. 9.3 Static Electricity Static electricity or surge voltage damages the Power SMD . 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 Power SMD. 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 LED will occur. Freon solvents should not be used to clean the LEDs because of worldwide regulations. 9.5 Heat Generation When the LEDs are illuminating, operating current should be decided after being considering the ambient maximum temperature. Please consider the heat generation of the LED when it is designed the PCB. IWS-L3512-UV-K1 Version of 2.0 PAGE : 7 / 10 Topview 3528 SMD LED IWS-L3512-UV-K1 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.
