5. Outline Drawing and Dimension Recommended Land Pattern 1. Tolerance is ±0.1 mm 2. The maximum compressing force is 15N on the silicone a 3. Do not place pressure on the encapsulation resin b Notes: 1) This LED has built-in ESD protection device(s) connected in parallel to LED Chip(s). 2) Ts point & measurement method 1 Measure the nearest point to the thermal pad as shown above. If necessary, remove PSR of PCB to reach Ts point. 2 Thermal pad must be soldered to the PCB to dissipate heat properly. Otherwise, LED can be damaged. 3) Precautions 1 The pressure on the LEDs will influence to the reliability of the LEDs. Precautions should be taken to avoid the strong pressure on the LEDs. Do not put stress on the LEDs during heating. 2 Re-soldering should not be done after the LEDs have been soldered. If re-soldering is unavoidable, LED`s characteristics should be carefully checked before and after such repair. 3 Do not stack assembled PCBs together. Since materials of LEDs is soft, abrasion between two PCB assembled with LED might cause catastrophic failure of the LEDs. http://www.samsungled.com 15 / 47

11. Precaution for use 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 Samsung Electronics, they should be packed by a sealed container with nitrogen gas injected.(shelf life of sealed bags: 12 months, temp. ~40, ~90%RH) LED의보관은청정한환경에서보존되어져야하며, 만약삼성전자로부터공급받는후 3개월또는그이상보관이필요하다면질소가스를동봉한보존용기에보관되어야함. ( 보존 bag의수명 : 12 개월, 보존온도 ~40, 습도 ~90%RH) 5) After storage bag is open, device subjected to soldering, solder reflow, or other high temperature processes must be: 보존 Bag이개봉된후에, 납땜이나 reflow등의높은온도에노출되는제품은다음의사항에부합되어야함. a. Mounted within 672 hours(28 days) at an assembly line with a condition of no more than 30 /60%RH, a. 제품은 30 /60%RH보다같거나낮은조립조건에서 672시간 (28일) 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. http://www.samsungled.com 22 / 47
7) Devices require baking before mounting, if humidity card reading is >60% at 23±5. 만약습도표시카드의수치가 23±5 에서 60% 이상이라면, 제품실장전 baking해야함. 8) Devices must be baked for 1 hour at 60±5, if baking is required. 만약 baking이필요하다면, 제품은 60±5 에서 1시간정도 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. 10) VOCs (volatile organic compounds) can be generated from adhesives, flux, hardener or organic additives used in luminaires (fixtures). Transparent LED silicone encapsulant is permeable to those chemicals and they may lead a discoloration of encapsualnt when they expose to heat or light. VOCs( 휘발성유기화합물 ) 는등기구에사용되는접착제, Flux, 경화제, 유기물첨가제에서발생하여 LED 실리콘봉지제를투과하고, 빛또는열에노출되었을때변색이발생할수있음. This phenomenon can cause a significant loss of light emitted(output) from the luminaires(fixtures). 이러한현상은등기구로부터나오는빛의중대한손실을줄수있음. In order to prevent these problems, we recommend you to know the physical properties of the materials used in luminaires, They must be selected carefully. 이러한문제발생방지를위해서, 등기구에사용되는자재에대한물성을알고주의하여선택되어야함. http://www.samsungled.com 23 / 47
11) Risk of Sulfurization (or Tarnishing) The LED from Samsung Electronics uses a silver-plated lead frame and its surface color may change to black(or dark colored) when it is exposed to sulfur(s), chlorine (Cl) or other halogen compound. 삼성전자의 LED는 Ag( 은 ) 을도금한리드프레임을사용함. 이리드프레임의표면이황 (S), 염소 (Cl), 또는다른할로겐화합물들에노출시 Ag( 은 ) 은검정 ( 또는어두운색 ) 으로바뀔수있음. Sulfurization of lead frame may cause intensity degradation, change of chromaticity coordinates and, in extreme cases, open circuit. It requires caution. 리드프레임의황화 (Sulfurization) 는광량저하, 색좌표변화및심한경우 LED 무등 (Open) 불량을일으킬수도있으니주의가필요함. Due to possible sulfurization of lead frame, LED should not be used and stored together with oxidizing substances made of materials in a following list, : Rubber, plain paper, lead solder cream and so on. 리드프레임황화 (Sulfurization) 의근원이될수있으니 LED 는아래의목록으로 만들어진산화성물질들과함께저장, 사용이불가함 : 고무, 일반종이, 납땜크림등 http://www.samsungled.com 24 / 47
