14. Precaution for Use ( 취급상주의사항 ) 1) For over-current-proof function, customers are recommended to apply resistors to prevent sudden change of the current caused by slight shift of the voltage. 과전류방지를위해전압의미세한이동에의해야기되는전류의순간변화를방지하기위해저항등의설치를권장함. 2) This device should not be used in any type of fluid such as water, oil, organic solvent, etc. When washing is required, IPA is recommended to use. 제품은물, 오일, 유기물과같은액체타입에서의사용은제한되며, 세정이필요할시에는 IPA 사용을권장함. 3) When the LEDs illuminate, operating current should be decided after considering the ambient maximum temperature. LED의발광시, 동작전류는주변최고온도를고려하여결정되어야함. 4) LEDs must be stored in a clean environment. If the LEDs are to be stored for 3 months or more after being shipped from SLED, they should be packed by a sealed container with nitrogen gas injected. (Shelf life of sealed bags: 12 months, temp. 0~40, 20~70 %RH) LED의보관은청정한환경에서보존되어져야하며, 만약삼성LED로부터공급받는후 3개월또는그이상보관이필요하다면질소가스를동봉한보존용기에보관되어야함. ( 보존 bag의수명 : 12 개월, 보존온도 0~40, 습도 20~70 %RH) 5) After storage bag is open, device subjected to soldering, solder reflow, orother high temperature processes must be: 보존 Bag이개봉된후에, 납땜이나 reflow등의높은온도에노출되는제품은다음의사항에부합되어야함. a.mounted within 168 hours (7 days) at an assembly line with a condition of no more than 30 /60 %RH, a. 제품은 30 /60 %RH보다같거나낮은조립조건에서 168시간 (7일) 이내에조립해야함. b. Stored at <10 %RH. b. 10 % 이하의상대습도에서보관되어야함. 6) Repack unused Products with anti-moisture packing, fold to close any opening and then store in a dry place. 사용하지않은제품은방습팩에넣어개봉부위를닫아서다시포장한후, 건조한장소에서보관할것을권장함.

7) Devices require baking before mounting, if humidity card reading is >60 % at 23±5. 만약습도표시카드의수치가 23±5 에서 60 % 이상이라면, 제품실장전에 baking하여야함. 8) Devices must be baked for 24 hours at 65±5, if baking is required. 만약 baking이필요하다면, 제품은 65±5 에서 24시간정도 baking 되어야함. 9) The LEDs are sensitive to the static electricity and surge. It is recommended to use a wrist band or anti-electrostatic glove when handling the LEDs. LED는정전기및서지에민감한제품이므로, LED 제품을다룰시에는정전기방지장갑이나손목밴드를사용하기를권장함. If voltage exceeding the absolute maximum rating is applied to LEDs, it may cause damage or even destruction to LED devices. 만약절대허용치를초과하는전압이 LED에가해지면, LED 소자는파괴되거나손상될수있음. Damaged LEDs may show some unusual characteristics such as increase in leak current, lowered turn-on voltage, or abnormal lighting of LEDs at low current. 손상된제품은누설전류의증가, Turn on 전압의저하, 저전류에서의점등불량등의이상거동을보일수있음.
