Application The LEDs described here are intended to be used for ordinary electronic equipment (such as office equipment, communication equipment and household applications).Consult Liteon’s Sales in advance for information on applications in which exceptional reliability is required, particularly when the failure or malfunction of the LEDs may directly jeopardize life or health (such as in aviation, transportation, traffic control equipment, medical and life support systems and safety devices). 2. Storage The storage ambient for the LEDs should not exceed 30°C temperature or 60% relative humidity. It is recommended that LEDs out of their original packaging are IR-reflowed within 672hrs. For extended storage out of their original packaging, it is recommended that the LEDs be stored in a sealed container with appropriate desiccant, or in a desiccators with nitrogen ambient. LEDs stored out of their original packaging for more than 672hrs should be baked at about 60 deg C for at least 24 hours before solder assembly. 3. Cleaning Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LED if necessary. 4. Soldering Recommended soldering conditions: Reflow soldering Pre-heat Pre-heat time Peak temperature Soldering time 120~150°C 120 sec. Max. 260°C Max. 5 sec. Max. Soldering iron 300°C Max. 3 sec. Max. (one time only) Temperature Soldering time 5. Drive Method An LED is a current-operated device. In order to ensure intensity uniformity on multiple LEDs connected in parallel in an application, it is recommended that a current limiting resistor be incorporated in the drive circuit, in series with each LED as shown in Circuit A below. Circuit model A LED Circuit model B LED (A) Recommended circuit. (B) The brightness of each LED might appear different due to the differences in the I-V characteristics of those LEDs. 6. ESD (Electrostatic Discharge) Static Electricity or power surge will damage the LED. Suggestions to prevent ESD damage: Use of a conductive wrist band or anti-electrostatic glove when handling these LEDs. All devices, equipment, and machinery must be properly grounded. Work tables, storage racks, etc. should be properly grounded. Use ion blower to neutralize the static charge which might have built up on surface of the LED’s plastic lens as a result of friction between LEDs during storage and handling. Part No. : LTST-S270KGKT Page : 9 of 11 BNS-OD-C131/A4 LITE-ON TECHNOLOGY CORPORATION Property of Lite-On Only ESD-damaged LEDs will exhibit abnormal characteristics such as high reverse leakage current, low forward voltage, or “ no lightup ” at low currents. To verify for ESD damage, check for “ lightup ” and Vf of the suspect LEDs at low currents. The Vf of “ good ” LEDs should be >2.0V@0.1mA for InGaN product and >1.4V@0.1mA for AlInGaP product. 7.
