datasheet smd ? a EASY2122BA0 8 copyright ? 2010, everlight americas inc. all rights reserved. release date : 26.nov .201 3 . issue no: 1 www.everlight americas .com 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 : t he leds should be kept at 30 or l ess and 90%rh or less. 2.3 after opening the package : t he led's floor life is 72 hours under 30 or less and 6 0% 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 con ditions. 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 n ot put stress on the leds during heating. pre-heating 150~200c 60~120sec. 3c/sec.max. above 217c 60~150sec. 260c max. 10sec. max. 6c/sec.max. above255c 30sec.max.
