Storage and application notices 1.Before opening the package: the LEDs should be kept at 5-3 and 6%RH or less; the LEDs should be used within three months ; 2.LED SMD is a kind of semiconductor that is sensitive to the humility. So after opening the package, LED must be used within 24Hrs, or else should be kept at 5-3 and 3%RH or less, and the LEDs should be used within 7days after opening the package. If unused LEDs remain, they should be stored in moisture proof packages, recommended to return the LEDs to the original moisture proof bag and to reseal the moisture proof bag again. If the LEDs have exceeded the storage time, baking treatment should be performed more than 24Hs at 6ºC±5ºC. 3.The internal and esterand boxes can not be contacted with ground to prevent absorption of moisture; 4.No acid, alkali, salt, corrosive and explosive gas; away from sunlight and keep the environment clean; 2 Application 1.Do not use any unknown chemical liquid to clean LED, it will damage the LED resin surface; use the alcohol under the room temperature if necessary but less than 1 min, or use the ultrasonic cleaning with proper characters, such as correct power, frequency,etc; 2.Do not touch the epoxy resin area when carrying LEDs by tweezers (as the following pictures), especially after the soldering process, the epoxy resin will turn to soft, the internal instruction will be damaged by the tweezers which cause the electric character s failure; nozzle is recommended by using SMT mounting. Correct Incorrect 3. Soldering iron: double-side soldering iron with power of less than 25W; soldering temperature: less than 3 ; soldering time: less than 3sec.; 1 time completed is recommended, if the 2 nd soldering process is Tel: 511-85513 Fax:511-85512861 Page 9 of 12
requested, 3mins must be left to ensure the high temperature status can return to room temperature; a. REFLOW soldering: set and test the temperature of the different area of REFLOW equipment in advance; b. To set the peak temperature according to different SMDs, but the actual peak temperature should be less than 26,processing time should be less than 1sec, only 1 time is allowed; 4.SMDs should be soldered at the coordinated position on the PCB ; 5.Note of Electrical matter: 1 One-way conduction, LED does not allow the reverse driving; 2 LED is a kind of constant current component which can not be lighted by the constant voltage mode; a smaller voltage fluctuation can cause the large current fluctuation which causes the failure of LED; Each LED should be drove under constant current mode if in a parallel circuit design, otherwise, the colour and brightness will be nonuniform; When the environmental temperature rising, the LED junction temperature will rise, internal resistance will decrease, so the current will be increased by the constant voltage power which short the life span; 3 If the brightness of lighting source can meet the requirement, we recommend using the driving current less than the rated current, in order to improve the product s reliability; 6.LED is a kind of electrostatic sensitive devises, anti-static measures have to be processed during storage and operation: 1 LED production workshop should lay anti-static floor and ground connection, the work table have to use the anti-static materials and cover a table mater with the surface resistance of 1 6-1 9 Ω 2 Production machine: REFLOW, SMT equipment, electric iron, test equipment; all the equipments must be well grounded, and the grounding alternating current impedance should be less than 1.Ω. A fan need to be installed on the equipments and production processes that easy to generate static electricity; the operators must wear anti-static clothing, shoes, wristband, and gloves, etc. in the process; 3 LEDs must be contained in the anti-static box, and all the package material should be the anti-static materials; 7.The details electronic characters can refer to our product specification.
