Over-current-proof Customer must apply resistors for protection , otherwise slight voltage shift will cause big current change ( Burn out will happen ). 2. Storage 2.1 Do not open moisture proof bag before the products are ready to use. 2.2 Before opening the package, the LEDs should be kept at 30℃ or less and 90%RH or less. 2.3 The LEDs should be used within a year. 2.4 After opening the package, the LEDs should be kept at 30℃ or less and 70%RH or less. 2.5 The LEDs should be used within 168 hours (7 days) after opening the package. 2.6 If the moisture absorbent material (silica gel) has faded away or the LEDs have exceeded the storage time, baking treatment should be performed using the following conditions. Baking treatment : 60±5℃ for 24 hours. 3. Soldering Condition 3.1 Pb-free solder temperature profile 3.2 Reflow soldering should not be done more than two times. 3.3 When soldering, do not put stress on the LEDs during heating. 3.4 After soldering, do not warp the circuit board.

Device No：DPT-091-008 http:\\www.everlight.com Prepared date：07-20-2005 Rev 4 Page: 6 of 9 Prepared by：JAINE TSAI PT91-21C 4.Soldering Iron Each terminal is to go to the tip of soldering iron temperature less than 280℃ for 3 seconds within once in less than the soldering iron capacity 25W. Leave two seconds and more intervals, and do soldering of each terminal. Be careful because the damage of the product is often started at the time of the hand solder. 5.Repairing Repair should not be done after the LEDs have been soldered. When repairing is unavoidable, a double-head soldering iron should be used (as below figure). It should be confirmed beforehand whether the characteristics of the LEDs will or will not be damaged by repairing. Everlight Electronics Co., Ltd.
