(even if the product is within the expiration date.)? baking conditions temperature time humidity 603oc 12 to 24h below 20%rh remark ? bake products in reel.? reel and embossed tape are easy to be deformed when baking, so please try not to apply stress on it. ? recommend bake once. 2.application methods 2-1. precaution for drive system and off mode design the circuit without the electric load exceeding the absolute maximum rating that applies on the products. if drive by constant voltage, it may cause current deviation of the led and result in deviation of luminous intensity, so we recommend to drive by constant current. (deviation of vf value will cause deviation of current in led.) furthermore, for off mode, please do not apply voltage neither forward nor reverse. especially, for the products with the ag-paste used in the die bonding, theres high possibility to cause electro migration and result in function failure. 2-2. operation life span theres possibility for intensity of light drop according to working conditions and environments (applied current, surrounding temperature and humidity, corrosive gases), please call our sales staffs for inquiries about the concerned application below. 1 longtime intensity of light life 2 on mode all the time 2-3.applied stress on product the top of the led is very soft, which the silicon resin is used as sealing resin. therefore, please pay attention to the overstress on it which may influence its reliability. 2-4.usage the product is led. we are not responsible for the usage as the diode such as protection chip, rectifier, switching and so on. downloaded from: http:///
