nichia sts-da1-4547 13 cautions (1) storage conditions temperature humidity time storage before opening aluminum bag 30 c 90%rh within 1 year from delivery date after opening aluminum bag 30 c 70%rh 168hours baking 65 5c - 24hours product complies with jedec msl 3 or equivalent. see ipc/jed ec std -020 for moisture-sensitivity details. absorbed moisture in led packages can vaporize and expand during soldering, which can cause interface delamination and result in optical performance degradation. products ar e packed in moisture-proof aluminum bags to minimize moisture absorption during transportation a nd storage. included silica gel desiccants change from blue to red if moistur e had penetrated bags. after opening the moisture -proof aluminum bag, the products should go through the so ldering process within the range of the conditions stated above. unused rema ining leds should be stored with silica gel desiccants in a hermetically sealed container, preferably the original moisture-proof bags for storage. after the period after opening storage time has been exceed ed or silica gel desiccants are no longer blue, the products should be baked. baking should only be don e once. although the l eads or electrode pads (anode and cathode) of the product are p lated with gold, prolonged exposure to a corrosive environment might cause the gold plated the leads or electrode pads to tarnish, and thus leading to difficulties in soldering. if unused leds remain, they must be stored in a hermetically sealed contain er. nichia recommends using the original moisture-proof bag for storage. do not use sulfur -containing materials in commercial products. some materials, such as seals and adhesives, may contain sulfur. the contaminated plating of leds might cause an open circui t. silicone rubber is recommended as a material for seals. be ar in mind, the use of silicones may lead to silicone contamina tion of electrical contacts inside the products, caused by low molecular weight volatile siloxane. to prevent water condensation, please avoid large tempera ture and humidity fluctuations for the storage conditions. do not store the leds in a dusty environment. do not expose the leds to direct sunlight and/or an env ironment where the temperature is higher than normal room temperature.
nichia sts-da1-4547 14 (2) directions for use in designing a cir cuit, the current through each led die must not exceed the abs olute maximum rating current specified for each die. it is recommended that each led die is driven at a constant current. when having the two or more dice within this product on at the same time, the total power dissipation for the led package must be within the absolute maximum value specified in this speci fication. this product should be operated using forward current. e nsure that the product is not subjected to either forward or reverse voltage while it is not in use. in particular, subjecting it to continuous reverse voltage may cause migration, which may cause damage to the led die. wh en used in displays that are not used for a long time, the main power supply should be switched off for safety. it is recommended to operate the leds at a current greater than 10% of the sorting current to stabilize the led charact eris tics. care must be taken to ensure that the reverse voltage will not exceed the absolute maximum rating when using the leds with matrix drive. ensure that excessive voltages such as lightning surges are no t applied to the leds. aging is recommended for detecting manufacturing and assembly defects. in particular, ensure that excessive current and/or voltage is not applied to the leds. this agin g should be conducted in environments where water condensation does not occur. this product can be used in indoor applications; however, when the leds are used in the following environments, incorporate sufficient measures into the display to prevent debris, water/moisture and gases that will adversely affect the product. - where water vapor is abundant - where water condensation is likely to occur - where water is likely to splash onto the l eds - where frost is likely to form on the surface of the leds (e.g. freezer, ice skating rink, etc.) - where dust, dirt, debris, loose metallic material s and/or gases that will adversely affect the product are present in areas where hydrogen sulfide, which is a sulfide -based gas, is present (e.g. hot springs and volcanic areas), and where salt is abundant (e.g. coastal areas), the life ma y be shortened. when this product is used for displays that will be instal led outside: the leds should be covered to avoid exposure to outdoor environments in conjunction with sufficient measures against direct sunlight, wet or damp conditions, and salt damage. when power is applied for the first time after installati on, the display should not be powered at 100% wattage since the leds may have absorbed moisture. before normal use of this display, operate the display at approximately 20 % wattag e for an initial time period. if the display units will be rented, those units should be selected carefully to ensure that the disp lay as a whole will appear the same color and brightness. if the display units are loaded onto and/or transporte d by ship, the damp environment on the vessel will cause condensatio n ; the display units should be packaged to prevent moisture ab sorption. if a display that has been, or is being, used is relocated, it is possible that degradation of the led has occurred. when transporting this display, provide sufficient prot ection for the leds in addition to the moisture-proof pack aging for the display. when this display is reinstalled, ensure to follow the installation instructions for environments an d use. if a secondary lens is used to collimate or diffuse the l ight, suf ficient verification should be performed to ensure that there are no issues (e.g. color variation ) prior to use. (3) handling precautions do not handle the leds with bare hands as it will contami nate the led surface and may affect the optical chara cteristics: it might cause the led to be deformed and/or the wire to br eak, which will cause the led not to illuminate. the lead could also cause an injury. when handling the product with tweezers, be careful not to ap ply excessive force to the resin. otherwise, the resin can be cut, chipped, delaminate or deformed, cau sing wire-bond breaks and catastrophic failures. dropping the product may cause damage. do not stack assembled pcbs together. failure to comply can cause t he resin portion of the product to be cut, chipped, delaminated and/or deformed. it may cause wire to break, leadi ng to catastrophic failures.
nichia sts-da1-4547 15 (4) design consideration pcb warpage after mounting the products onto a pcb can cause the package to break. the led should be placed in a way to minimize the stress o n the leds due to pcb bow and twist. the position and orientation of the leds affect how muc h mechanical stress is exerted on the leds placed near the score l in es. the led should be placed in a way to minimize the stress o n the leds due to board flexing. board separation must be performed using special jigs, not usin g hands. (5) electrostatic discharge (esd) the products are sensitive to static electricity or surge volt age. esd can damage a die and its reliability. when handling the products, the following measures against el ectrostatic discharge are strongly recommended: eliminating the charge grounded wrist strap, esd footwear, clothes, and flo ors grounded workstation equipment and tools esd table/shelf mat made of conductive materials ensure that tools (e.g. soldering irons), jigs and machines that are being used are properly grounded and that proper grounding techniques are used in work areas . for devices/equipment that mount the leds, protection against surge voltages should also be used. if tools or equipment contain insulating materials such as glass or plastic, the following measures against electrostatic discharge are strong ly recommended: dissipating static charge with conductive materials preventing charge generation with moisture neutralizing the charge with ionizers the customer is advised to check if the leds are damaged b y esd when performing the characteristics inspection of the leds in t he application. damage can be detected with a forward voltage measurement or a light- up test at low current (1ma). leds with esd -damaged dice (i.e. other than red) may have an increased leakage current, current flow at a low voltage, or no longer illuminate at a low current. failure criteria: v f <2.0v at i f =0.5ma (6) thermal management proper thermal management is an important when designing produ cts with leds. led die temperature is affected by pcb thermal resistance and led spacing on the board. p lease design products in a way that the led die temperature does not exceed the maximum junction temperature (t j ). drive current should be determined for the surrounding ambien t temperature (t a ) to dissipate the heat from the product. (7) cleaning the leds should not be cleaned with water, benzine, and/or thinner. if required, isopropyl alcohol (ipa) should be used. ot her solvents may cause premature failure to the leds due to the damage to the resin portion. the effects of such so lvents should be verified prior to use. in addition, the use of cfcs such as freon is heavily regu lated. when dust and/or dirt adheres to the leds, soak a cloth with isopropyl alcohol (ipa), then squeeze it before wip ing the leds. ultrasonic cleaning is not recommended since it may have adverse eff ects on the leds depending on the ultrasonic power and how led is assembled . if ultrasonic cleaning must be used, the customer is advised to make sure the leds will not be damaged prior to cleaning.
nichia sts-da1-4547 16 (8) eye safety in 2006, the international electrical commission (iec) publ ished iec 62471:2006 photobiological safety of lamps and lamp systems, which added leds in its scope. on the other hand, the iec 60825-1:2007 laser safety sta ndard removed leds from its scope. however, please be advised that some countries and region s have adopted standards based on the iec laser safety standard iec 60825-1:2011 2001, which still includes leds in its scope. most of nichia's leds can be classified as belonging into either the exempt group or risk group 1. high-power leds, that emit light containing blue wavel engths, may be classified as risk group 2. please proceed with caution when viewing directly any leds driv en at high current, or viewing leds with optical instruments which may greatly increase the damages t o your eyes. viewing a flashing light may cause eye discomfort. when incorpo rating the led into your product, please be careful to avoid adverse effects on the human body caused by light stimulation. (9) others this product is intended to be used for general lighting, household appliances, electronic devices (e.g. mobile communicati on devices); it is not designed or manufactured for use in appl ications that require safety critical functions (e.g. aircraft, a utomobiles, combustion equipment, life support systems, nuclear reactor cont rol system, safety devices, spacecraft, submarine repeaters, traffic control equipment, trains, vessels, etc.). if the le ds are planned to be used for these applications, unless otherwise detailed in the specification, nichia will neither guarantee that the product is fit for that purpose nor be responsible for any resulting property damage, injuries and/or loss of life/health. this product does not comply with iso/ts 16949 and is not intended for automotive applications. the customer shall not reverse engineer by disassembling or anal ysis of the leds without having prior written consen t from nichia. when defective leds are found, the customer shal l inform nichia directly before disassembling or analysis. the specifications and appearance of this product may change without notice; nichia does not guarantee the contents of this specification. both the customer and nichia will agree on the official specifications of supplied product s before the volume production of a program begins.
