11/ 12 9. Cautions on use 9-1.Circuit Layout In general, The LEDs have a variation of forward voltage. Using LEDs with different forward voltages in a circuit with on resistor for the complete circuit causes different forward currents for each LED. This may lead to a variation in brightness. To avoid brightness variation of LEDs, the use of matrix circuit with one resistor for each LED is recommended. 9-2. Over-current-proof Customer must apply resistors for protection, others slight voltage shift will cause big current change ( Burn out will happen ). 9-3. For the Storage - Proper temperature and RH conditions for storage are : 5 ~35, RH 60%. - Do not open moisture-proof bag before the products are ready to use. - Store products in a moisture-proof bag with a desiccant(silica gel) after open. - These products should be used within 168 hours after opening the bag based upon storage condition. - These products must be baked to remove moisture before using them if the Silica gel loses its blue color. Conditions for baking are 605, 20% (RH) and 24 hours maximum. (For reeled status without bag) - Considering the tape life, we suggest our customers to use our products within a year(from production date) 9-4. LG Innotek will not be held responsible for any damage to the user that may result from accidents or any other reasons during operation of the user s unit if use to exceed the absolute maximum ratings, or not keep the matters that demand special attention.

If temperature is higher, time shorter (+10-1sec). Power dissipation of Iron should be smaller than 15W, and temperature should be controllable. Surface temperature of the device should be under 230. 10-4. Rework 1) Customer must finish rework within 5sec under 245. 2) The head of Iron can not touch copper foil. 3) Twin-head type is preferred. Thickness of thin paste ( O ) ( X )
