See IPC/JEDEC STD-020 for the details of the moisture sensitivity levels. ● Interface delamination can occur due to vaporization and expansion of absorbed moisture in the LED packages caused by soldering heat, which may result in degradation in optical performance. To minimize moisture absorption into the products during the transportation and storage, the products are packed in a moisture-proof aluminum bag. Desiccants (silica gel) inside the packing turn from blue to red as it absorbs moisture. ● After opening the moisture-proof aluminum bag, the products should be completed soldering process within the range of the conditions above. If unused LEDs remain, they should be stored with desiccants (silica gel) in hermetically sealed container. Nichia recommends using the original moisture-proof bag for storage. ● After the "Period After Opening" specified above, or if the desiccants (silica gel) are no longer blue, the products need to be baked. Note that baking must only be done once. ● Although the leads or electrode pads (anode and cathode) of the product are plated 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 container. 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 circuit. Silicone rubber is recommended as a material for seals. Bear in mind, the use of silicones may lead to silicone contamination of electrical contacts inside the products, caused by low molecular weight volatile siloxane. ● To avoid condensation, the products must not be stored in the areas where temperature and humidity fluctuate greatly. (2) Directions for Use ● In designing a circuit, the current through each LED must not exceed the Absolute Maximum Rating specified for each LED. It is recommended to use Circuit B which regulates the current flowing through each LED. In the meanwhile, when driving LEDs with a constant voltage in Circuit A, the current through the LEDs may vary due to the variation in Forward Voltage characteristics of the LEDs. (A) (B) ... ... ● This product should be operated in forward bias. A driving circuit must be designed so that the product is not subjected to either forward or reverse voltage while it is off. In particular, if a reverse voltage is continuously applied to the product, such operation can cause migration resulting in LED damage. ● For stabilizing the LED characteristics, it is recommended to operate at 10% of the rated current or higher. ● For outdoor use, necessary measures should be taken to prevent water, moisture and salt air damage. ● This LED also emits visible light. Please take notice of visible light spectrum, in case you use this LED as light source of sensors etc. 13 NICHIA STS-DA1-1793 <Cat.No.110530> (3) Handling Precautions ● When handling the product, do not touch it directly with bare hands as it may contaminate the surface and affect on optical characteristics. In the worst cases, excessive force to the product might result in catastrophic failure due to package damage and/or wire breakage. ● When handling the product with tweezers, make sure that excessive force is not applied to the resin portion of the product. Failure to comply can cause the resin portion of the product to be cut, chipped, delaminated and/or deformed, and wire to be broken, and thus resulting in catastrophic failure. ● If the product is dropped, it might be damaged. ● 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, and wire to be broken, and thus resulting in catastrophic failure. (4) Design Consideration ● PCB warpage after mounting the products onto a PCB can cause the package to break. The LEDs should be placed so as 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 exerted on the LEDs placed near the score lines. The LEDs should be placed so as to minimize the stress on the LEDs due to board flexing. ● Board separation must be performed using special jigs, not with hands. ● If an aluminum PCB is used, customer is advised to verity the PCB with the products before use. Thermal stress during use can cause the solder joints to crack. (5) Electrostatic Discharge (ESD) ● The products are sensitive to static electricity or surge voltage. An ESD event may damage its die or reduce its reliability performance. When handling the products, measures against electro static discharge, including the followings, are strongly recommended. Eliminating the charge; Wrist strap, ESD footwear and garments, ESD floors Grounding the equipment and tools at workstation ESD table/shelf mat (conductive materials) ● Proper grounding techniques are required for all devices, equipment and machinery used in the assembly of the products. Also note that surge protection should be considered in the design of customer products. ● If tools or equipment contain insulating materials, such as glass or plastic, proper measures against electro static discharge, including the followings, are strongly recommended. Dissipating the charge with conductive materials Preventing the charge generation with moisture Neutralizing the charge with ionizers ● When performing the characteristics inspection of the LEDs in your application, customer is advised to check on the LEDs whether or not they are damaged by ESD. Such damage can be detected during forward voltage measurement at low current. (the recommended current is 1mA or lower) ● ESD-damaged LEDs may have a current flow at low voltage. Failure Criteria: VF<2.0V at IF=0.5mA (6) Thermal Management ● Thermal management is an important factor when designing your product by using the LEDs. The rise in LED die temperature can be affected by PCB thermal resistance or/and LED spacing as mounted on the board. Customer is advised to design the product to ensure that the LED die temperature does not exceed the required maximum Junction Temperature (TJ). ● Drive current should be determined for the surrounding ambient temperature (TA) to dissipate the heat from the product. (7) Cleaning ● If required, isopropyl alcohol (IPA) should be used. Other 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 for the LEDs since it may adversely effect on the LEDs by the ultrasonic power and LED assembled condition. If it is unavoidable, customer is advised to check prior to use that the cleaning will not damage the LEDs. 14 NICHIA STS-DA1-1793 <Cat.No.110530> (8) Eye Safety ● The International Electrical Commission (IEC) published in 2006, IEC 62471:2006 Photobiological safety of lamps and lamp systems which includes LEDs within its scope. Meanwhile LEDs were removed from the scope of the IEC 60825-1:2007 laser safety standard, the 2001 edition of which included LED sources within its scope. However, keep it mind that some countries and regions have adopted standards based on the IEC laser safety standard IEC 60825-1:2001 which includes LEDs within its scope. Following IEC 62471:2006, most of Nichia LEDs can be classified as belonging to either Exempt Group or Risk Group 1. Especially a high-power LED, that emits light containing blue wavelengths, may be in Risk Group 2. Great care should be taken when viewing directly the LED driven at high current or the LED with optical instruments, which greatly increase the hazard to your eyes. ● Viewing a flashing light may cause eye discomfort. When incorporating the LED into your product, precaution should be taken to avoid adverse effect on human body caused by the light stimulus. ● The products are UV light LEDs, and radiate intense UV light during operation. Since UV light can be harmful to eyes, do NOT look directly into the UV light, even through an optical instrument. In case of the light reflection, UV protective glasses are required to use in order to avoid damage by the light. (9) Others ● The LEDs described in this brochure are intended to be used for ordinary electronic equipment (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, submersible repeaters, nuclear reactor control 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 shall inform Nichia directly before disassembling or analysis. ● Customer and Nichia shall agree the official specification of supplied products prior to the start of a customer’s volume production. ● The appearance and specifications of the product may be modified for improvement without notice. 15
