Storage To prevent moisture absorption into SMD LEDs during the transportation and storage , the LEDs are packed in a moisture-barrier bag. Desiccants and a humidity indicator are packed together with the LEDs as secondary protection The shelf life of LEDs stored in the original sealed bag at <40℃ and < 90% RH is 12 months. Baking is required if the shelf life has expired Before opening the packaging , check for air leaks in the bag. After the bag is opened, the SMD LEDs must be stored at <30℃ and < 60% RH. Under these conditions, SMD LEDs must be used within 24 hours. If the LEDs are not within 24 hours after removal from the bag , baking is required Take the material out of the packaging bag before baking. Do not open the oven door frequently during the baking process. 2. Soldering (1) Manual soldering with a soldering Iron Use a soldering iron of less than 25 watts is recommended . The iron temperature must be kept below 315℃ And soldering time no more than 2 seconds. The epoxy resin of an SMD LED should not contact the tip of the soldering iron. No mechanical stress should be exerted on the resin portion of an SMD LED during soldering. Handling of an SMD LED should be done only when the package has been cooled down to below 40℃ (2)Reflow soldering Temperature profile Temperature Peak temperature Melting-point Pre-heat Soak Reflow Cooling Time Http://www.foryard.com Page ： 7/8 Model.

If modification cannot be avoided, the modification must be pre-qualified to avoid damage to the SMD LEDs. Reflow soldering should not be done more than one time No stress should be exerted on the package during soldering. (3) Recommend Soldering pad design(unit=mm) 3. Static Electricity Static Electricity and surge voltage damage the LEDs. So it is recommended that an ESD wrist band, ESD shoe strap or an anti-electrostatic glove be used when handling the LEDs. All devices, equipment and machinery must be properly grounded 4. Others Reverse voltage should not exceed the absolute maximum rating on the data sheet. The colour of the LEDs is changed slightly an operating current and thermal. 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. The influence of ultrasonic cleaning on the leds depends on factors such as ultrasonic power and the way. High-brightness LED light may injure human eyes. Avoid looking directly into lighted LED The appearance and specifications of the product may be modified for improvement without notice. Http://www.foryard.com Page ： 8/8
