8. packing specification (1) moisuture-proof packing to prevent moisture absorption during transportation and strage, reels are packed in aluminium envelpoed which contain a desicant with a humidity indicator. (2) storageto prevent moisture absorption, it is strongly recommended that reels (in bulk ore taped) should be stored in the dry box(or the desicator) with a desiccant as the appropriate strage place. if not, the following condition 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. (3) using condition this devices contain silver plated elctrode. so, when being exposed to environment which contains corrosive gases, the silver plating becomes tarnished. tarnished plating may lead to poor solderability and degradation of optical characteristics. please do not exposed this debvice to corrosive atomosphere anytime (during storage, or after mounted). please take care above when designing your product. citizen electronics co.,ltd. japan symbol citiled name cl-l430-mc1ww1-a data sheet 8/12 aluminum envelop desiccant label reel polyester zip fastener ref.ce-p1597 10/11
9. precautions 1. handling precaution(1). please do not place strong pressure on the silicone dome lens. (2). avoid any contact by a sharp metal nail or other materials with the silicone dome lens. (3) pick and place when mounting leds using automated equipment, contact pressure on the silicone dome lens should be minimized through use of such as a vacuum chuck. please do not apply strong diagonal force to the dome lens or fatal damage will occur. (4). pcb handling bending the circuit board with soldered leds may cause breakage of leds. please take care to bow, twist, and warpage of fthe pcb. 2. lighting at low current a minimum current value of lighting of all dice is 6ma.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. 3. handling of static electricitythese products are sensitive to static electricity charge. please take measure to prevent any static electricity being produced as the wearing of a wristband or anti-static gloves when handling this product. all devices, equipment, and machinary 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 checkwhether the assembled leds are damaged by static electricity or not. it is easy to find static-damaged leds by a light-on test. data sheet 9/12 citizen electronics co.,ltd. japan symbol citiled name cl-l430-mc1ww1-a dome lens ref.ce-p1597 10/11
9. precautions (continued) 4. designing precautiona 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. ex. circuit with resistor. cl-l430 has small electrode at the side of package.please take care about shortage with conductive rubbish. 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. please be aware that this product should not come into contact with any other parts in assembled status. 5. soldering (1) lead free soldering 1) following soldering paste is recommended melting temperature : 216~220c.composition : sn 3.5 ag 0.75 cu 2) the temperature profile at the top surface of the parts is recommended as below.3) it is requested that products shuld 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. citizen electronics co.,ltd. japan data sheet 10/12 symbol citiled name cl-l430-mc1ww1-a r r r r r r r 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 fig : small electrode cathode anode ref.ce-p1597 10/11
9. precautions (continued) 6. heat generationas this product is designed with consideration of the heat release property of module, a heat release design is required to use this product effficiently. please ensure that heat generation is not in excess of the absolute maximum rating. factors responsible for an increase in temperature include heat generation attributed to ambient temperature conditions or power dissipation. thus, drive condition should be taken into consideration, depending on ambient temperature(ta). *citizen electoronics cannnot guarantee if usage exeeds this recommended conditions. please use it after sufficient verification is carried out on your own risk if necessary. 7. 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 white leds can be classified as belonging to either exempt group or risk group 1. - however, 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 high-power 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. - it is recommended to regard the evaluation of stand-alone led packages as a reference and to evaluate the customer's final product. 8. the use of class 2 power supply is assumed for this product. 9. if the product might to be used under the following conditions, the customer must evaluate its approproateness them. this product is not designed for use under the following conditions. in places where the product might: - get wet due to rain - suffer from damage caused by salt. - be exposed to corrosive gas such as cl, h2s, nh3, so2, nox and so on. - be exposed to dust, fluid or oil. citizen electronics co.,ltd. japan symbol citiled data sheet 11/12 name cl-l430-mc1ww1-a ref.ce-p1597 10/11
