Note : In case the soldered products are reused in soldering process, we don’t guarantee the products. -10- <070625> Rev. 0.0 서식번호 : QP-7-03-05 (Rev.00) WHITE LAMP LED LW340AS Precaution for Use 1) Storage • Before opening the package a. Avoid the absorption of moisture, we recommended to store the LEDs in a dry box(or desiccator) with a desiccant . Otherwise, store them in the following environment: Temperature : 5℃~30℃ Humidity : 50% max. b. The products should be used in 3 months. It is recommended that the LEDs be used as soon as possible. • After opening the package a. Soldering should be done right after opening the package(within 24Hrs). b. Keeping of a fraction - Sealing - Temperature : 5 ~ 40℃, Humidity : less than 30% c. If the package has been opened more than 1week or the color of desiccant changes, Components should be dried for 10-12hr at 60±5℃ • Any mechanical force or any excess vibration shall not be accepted to apply during cooling process to normal temp. after soldering. • Avoid quick cooling • Leadframes are silver plated SPCC. The silver plate surface may be affected by environments which contains corrosive substances. Please avoid conditions which may cause the LEDs to corrode, tarnish or discolor. 2) Lead Forming • When the lead forming is required before soldering , care must be taken to avoid any bending and mechanical stress. The stress to the base may damage the LEDs. • When mounting the LEDs onto a PCB, the holes on the circuit board should be exactly aligned with the leads of the LEDs. • It is recommended that tooling made to precisely form and cut the leads to length rather than rely on hand operating. -11- <070625> Rev. 0.0 서식번호 : QP-7-03-05 (Rev.00) WHITE LAMP LED LW340AS 3) Static Electricity • Static Electricity and surge voltage damage the LEDs. So it is recommended that a wrist band or an anti-electrostatic glove be used when handling the LEDs. • All devices, equipment and machinery must be grounded properly. It is recommended that precautions should be taken against surge voltage to the equipment that mounts the LEDs. 4) Heat Generation • Thermal is one of the important parameters to design the end product. Please consider the heat generation of the LEDs. • The operating current should be decided after considering the ambient maximum temperature of LEDs. 5) Others • The color of the LEDs is changed slightly an operating current and thermal. • Anti radioactive ray design is not considered for the products listed here. • Gallium arsenide is used in some of the products listed in this publication. These products are dangerous if they are burned or smashed in the process of disposal. It is also dangerous to drink the liquid or inhale the gas generated by such products when chemically disposed. • This device should not be used in any type of fluid such as water, oil, organic solvent and etc. When washing is required, IPA(Isopropyl Alcohol) should be used. • When the LEDs are illuminating, operating current should be decided after considering the junction temperature. Cf.) Please refer Ambient temperature vs. Forward Current graph on page 5 • The appearance and specifications of the product may be modified for improvement without notice.
