nichia sts-da1-2621 13 cautions (1) lead forming when forming leads, the leads shou ld be bent at a point at lease 3 mm from the base of the epoxy bulb. do not use the base of the leadframe as a fulcrum during lead forming. lead forming should be done before soldering. do not apply any bending stress to the base of the lead. the stress to the base may damage the led's characteristics or it may break the leds. when mounting the product onto a printed circuit board, the via-holes on the board should be exactly aligned with the lead pitch of the product. if the leds are mounted with stress at the leads, it caus es deterioration of the epoxy r esin and this will degrade the leds. (2) storage shelf life of the products in unopened bag is 3 mont hs(max.) at <30c and 70% rh from the delivery date. if the shelf life exceeds 3 months or more, th e leds need to be stored in a sealed container with silica gel desiccants to ensure their shelf life will not exceed 1 year. nichia led leadframe are silver plat ed copper alloy. this silver surface may be affected by environments which contain corrosive substances. please avoid conditio ns which may cause the led to corrode, tarnish or discolor. this corrosion or discoloration may cause difficulty during soldering operation. it is recommended that the le ds be used as soon as possible. to avoid condensation, the pr oducts must not be stored in the areas where temperature and humidity fluctuate greatly. (3) directions for use when designing a circuit, the curre nt through each led must not exceed the absolute maximum rating. operating at a constant current per led is recommended. in case of operating at a constant voltage, circuit b is recommended . if the leds are operated with constant voltage using circui t a, the current through the leds may vary due to the variation in forward voltage ch aracteristics of the leds. (a) ... (b) ... leds should be operated in forward bias. driving circuits must not subject leds to either forward or reverse voltage while off . continuous reverse voltage can cause migration and led damage. it is recommended to operate the leds at a current greater th an 10% of the sorting current to stabilize the led characteristic s. care must be taken to ensure th at the reverse voltage will not exceed the absolute maximum rating when using the leds with matrix drive. for outdoor use, necessary measures should be take n to prevent water, moisture and salt air damage. care must be taken for led leads to be kept dry. (4) handling precautions do not handle leds with bare hands, it may contamin ate the led surface and affect optical characteristics. in the worst case, catastrophic failure from excess pressu re through wire-bond breaks and package damage may result. dropping the product may cause damage. do not stack assembled pcbs together. failure to comply can cause the resin portion of the product to be cut, chipped, delaminated and/or deformed. it may cause wi re to break, leading to catastrophic failures. (5) 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 on the leds due to pcb bow and twist. the position and orientation of the leds affect how much mechanical stress is exerte d on the leds placed near the score lines. the led should be placed in a way to minimize the stress on the leds due to board flexing. board separation must be performed using special jigs, not using hands.
nichia sts-da1-2621 14 (6) electrostatic discharge (esd) the products are sensitive to static electricity or surge voltage. esd can damage a die and its reliability. when handling the products, the following measures against electrostatic discharge are strongly recommended: eliminating the charge grounded wrist strap, esd footwear, clothes, and floors grounded workstation equipment and tools esd table/shelf mat made of conductive materials proper grounding is required for all devices, equipment, and machinery used in product assembly. surge protection should be considered when designing of commercial products. if tools or equipment contain insulating materials such as glass or plastic, the following measures against electros tatic discharge are strongly recommended: dissipating static charge with conductive materials preventing charge generation with moisture neutralizing the charge with ionizers the customer is advised to chec k if the leds are damaged by esd when performing the characteristics insp ection of the leds in the application. damage can be detected with a forw ard voltage measurement at low current ( 2ma). esd damaged leds may have an increased leak age current, current flow at a low voltage. failure criteria: v f <2.0v at i f =1.0ma (7) thermal management proper thermal management is an impo rtant when designing products with le ds. led die temperature is affected by pcb thermal resistance and led spacing on the board. please 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 ambient temperature (t a ) to dissipate the heat from the product. (8) cleaning 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 solvents should be verified prior to use. in addition, the use of cfcs such as freon is heavily regulated. ultrasonic cleaning is not recommended sinc e it may have adverse effects on the leds depending on the ultrasonic power and how led is assembled. if ultrasonic cleaning must be used, the customer is advise d to make sure the leds will not be damaged prior to cleaning. (9) eye safety in 2006, the international electrical commission (iec) published 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 standard removed leds from its scope. however, please be advised that some countries and regions have adopted standards based on the iec laser safety standard iec 60825- 1:20112001, which still includes leds in its scope. most of nichia's leds can be classified as belo nging into either the exempt group or risk group 1. high-power leds, that emit ligh t containing blue wavelengths, may be classified as risk group 2. please proceed with caution when viewing directly any leds driven at high current, or viewing leds with optical instruments which may greatly increase the damages to your eyes. viewing a flashing light may cause eye discomfort. when incorporating the led into your product, please be careful to avoid adverse effects on the human body caused by light stimulation.
nichia sts-da1-2621 15 (10) others the leds described in this brochure are intended to be used for ordinary electronic equipmen t (such as office equipment, communications equipment, measurement instruments and household appliances). consult nichia's sales staff in advance for information on the applications in which exceptional quality and reliability are required, particularly when the failure or malfunction of the leds may directly jeopardize life or health (such as for airplanes, aerospace, submersibl e repeaters, nuclear reactor co ntrol system, automobiles, traffic control equipment, life support systems and safety devices). the customer shall not reverse engineer by disassembling or analysis of the leds without having prior written consent from nichia. when defective leds are found, the customer sh all inform nichia directly before disassembling or analysis. both the customers and nichia will agree on official specificatio ns of supplied produc ts before a customer 's volume production . specifications and appearance subject to change for improvement without notice.
