datasheet smd ?side view leds EAPL3811WA2 precautions for use 1. 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 used within one year and kept at 30 or less and 70%rh or less. 2.3 after opening the package: we recommend that the led should be soldered quickly (within 3 days). the soldering condition is 30 or less and 60%rh or less. if unused leds remain, it should be stored in moisture proof packages. 2.4 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: 605 for 24 hours. (one time only) 3. soldering condition 3.1 pb-free solder temperature profile 120 sec. max. 1~5 c / sec. pre-heating 180~200c 60 sec. max. above 220c 260c. max. 10 sec. max. 1~5 c / sec. . 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. 4. soldering iron each terminal is to go to the tip of soldering iron temperature less than 350 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. www.everlightamericas.com 1 2
datasheet smd ?side view leds EAPL3811WA2 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. 6. handling indications during processing, mechanical stress on the surface should be minimized as much as possible. sharp objects of all types should not be used to pierce the sealing compound. www.everlightamericas.com 1 3
