8/12 8. packing specifications 81. moistureproof packing to prevent moisture absorption during transportation and storage, reels are packed in aluminum envelopes which contain a desiccant with a humidity indicator. 82. storage to prevent moisture absorption, it is strongly recommended that reels (in bulk or taped should be stored in the dry box (or the desiccator) with a desiccant as the appropriate storage place. if not, the following is recommended. temperature : 5~30c humidity : 60%rh max. the devices should be mounted within 168h (7days) after unpacking. if you store the unpacked reels, please store them in the dry box or seal them into the envelop again. 83. other (storage and using conditions) this device contain silver plated electrode. so, when being exposed to enviroment which contains corrosive gases, the silver plating becomes tarnished. tarnished plating may lead to poor solderbility and degradation of optical characteristics. please do not expose this device to corrosive atomosphere anytime (during storage, or after mount) please take care the above when designing your product. data sheet symbol citiled name cll400mc1l1a citizen electronics co., ltd. japan aluminum envelop desiccant label reel polyester zip fastener ref.ce-p1158 05/11
9/12 9. precautions 91 handling precaution (1). avoid the application of any stress to the encupsulant. (2). avoid any contact by a sharp metal nail or other materials with the encupsulant. (3).pick and place recommend condition : nozzle inner radius R 4.4mm avoid direct contact to the encapsulant with the nozzle. (4). pcb handling bending the circuit board with soldered leds may cause breakage of leds. please take care to bow, twist, and warpage the pcb. 92. lighting at a low current a minimum current value of lighting of all dice is 30ma. when a minimal current is applied, led dice may look different in their brightness due to the individual difference of the led element, and it is not a failed product. 93. handling of static electricity these products are sensitive to static electricity charge. please take measures to prevent any static electricity being produced such as the wearing of a wristband or antistatic gloves when handling this product. all devices, equipment and machinery must be properly grounded. it is recommended that precautions be taken against surge voltage to the equipment that mounts the leds. when inspecting the final products in which leds were assembled, it is recommended to check whether the assembled leds are damaged by static electricity or not. it is easy to find staticdamaged leds by a lighton test. symbol citiled name nolighting die in package is unacceptable i f =6ma/pkg condition judgmental criterion data sheet cll400mc1l1a citizen electronics co., ltd. japan encupsulant(hatching area) ng bad ex : narrow nozzle encupsulant(hatching area) cathode mark ng bad ex : narrow nozzle ex : pick up area =4.4mm ex : pick up area ref.ce-p1158 05/11
10/12 94. designing precaution a constant current circuit is recommended as a drive circuit. when using two or more led packages, connect current limiting resistor in series on each path is recommended. please design a circuit that prevents any reverse voltage (excess current) from being applied to this product instantaneously when the circuit is on or off. cll400 has small electrode at the side of package. please take care about shortage with conductive rubbish. 95. soldering (1) lead free soldering 1) following soldering paste is recommended melting temperature : 216 ~ 220c. composition : sn 3.5ag 0.75cu 2) the temperature profile at the top surface of the parts is recommended as shown below. 3) it is requested that products should be handled after their temperature has dropped down to the normal room temperature (2) recommended soldering pattern mountability and solderability need to be optimized with actual conditions such as amount of solder, reflow temperature applied in the process. symbol citiled data sheet name cll400mc1l1a citizen electronics co., ltd. japan 140sec 160 ~ 180 c 4 c /sec. max t e m p e ra tu re time 4 c /sec. max 260 c max 220 c 60 ~ 70sec 3 sec . max ex : constant current circuit with resistor fig : small electrode cathode anode r r r r r r r ref.ce-p1158 05/11
11/12 96. heat generation as this product is designed with consideration of the heat release property of module, a heat release design is required to use this product efficiently. please ensure that heat generation is not in excess of the absolute maximum rating. (refer to 41 performance) factors responsible for an increase in temperature include heat generation attributed to ambient temperature conditions or power dissipation. thus, drive conditions should be taken into consideration, depending on ambient temperature (ta). * citizen electronics cannot guarantee if usage exceeds this recommended conditions. please use it after sufficient verification is carried out on your own risk if necessary. 97. eye safety the international electrical commission (iec) published in 2006 iec 62471 2006 photobiological safety oflamps and lamp systems which includes leds within its scope. when sorting single leds according to iec 62471, most leds can be classified as belonging to either exempt group or risk group 1. optical characteristics of leds such as radiant flux, spectrum and light distribution are factors that affect the risk group determination of the led, and especially a highpower led, that emits light containing blue wavelengths, may have properties equivalent to those of risk group 2. great care should be taken when directly viewing an led that is driven at high current, has multiple uses as a module or when focusing the light with optical instruments, as these actions may greatly increase the hazard to your eyes. in addition, led sources that were included within the scope of iec 608251 / edition 1.2 laser safety standard, published 2001 were removed from the scope of the iec 608251 / edition 2.0 revised 2007. however, keep in mind that some countries and regions have adopted standards based on the iec laser safety standard iec 608251:2001 which includes leds within its scope. 97. other this product complies with rohs directives. name cll400mc1l1a citizen electronics co., ltd. japan data sheet symbol citiled ref.ce-p1158 05/11
