Consequently, the color of the LEDs is changed a little by an operating current. Care should be taken after due consideration when using LEDs. (1) Moisture Proof Package * When moisture is absorbed into the SMT package it may vaporize and expand during soldering. There is a possibility that this can cause exfoliation of the contacts and damage to the optical characteristics of the LEDs. For this reason, the moisture proof package is used to keep moisture to a minimum in the package. * The moisture proof package is made of an aluminum moisture proof bag. A package of a moisture absorbent material (silica gel) is inserted into the aluminum moisture proof bag. The silica gel changes its color from blue to pink as it absorbs moisture. (2) Storage * Storage Conditions Before opening the package : The LEDs should be kept at 30C or less and 90%RH or less. The LEDs should be used within a year. When storing the LEDs, moisture proof packaging with absorbent material (silica gel) is recommended. After opening the package : The LEDs should be kept at 30C or less and 70%RH or less. The LEDs should be soldered within 168 hours (7days) after opening the package. If unused LEDs remain, they should be stored in moisture proof packages, such as sealed containers with packages of moisture absorbent material (silica gel). It is also recommended to return the LEDs to the original moisture proof bag and to reseal the moisture proof bag again. * If the moisture absorbent material (silica gel) has faded away or the LEDs have exceeded the storage time, baking treatment should be performed using the following conditions. Baking treatment : more than 24 hours at 65 5C * Nichia LED electrodes and leadframes are silver plated copper alloy. The silver surface may be affected by environments which contain corrosive substances. Please avoid conditions which may cause the LED to corrode, tarnish or discolor. This corrosion or discoloration might lower solderability or might affect on optical characteristics. * Please avoid rapid transitions in ambient temperature, especially in high humidity environments where condensation can occur. (3) Heat Generation * Thermal design of the end product is of paramount importance. Please consider the heat generation of the LED when making the system design. The coefficient of temperature increase per input electric power is affected by the thermal resistance of the circuit board and density of LED placement on the board, as well as other components. It is necessary to avoid intense heat generation and operate within the maximum ratings given in this specification. * The operating current should be decided after considering the ambient maximum temperature of LEDs. -4- Nichia STSE-CC7044B <Cat.No.070606> (4) Soldering Conditions * The LEDs can be soldered in place using the reflow soldering method. Nichia cannot make a guarantee on the LEDs after they have been assembled using the dip soldering method. * Recommended soldering conditions Pre-heat Pre-heat time Peak temperature Soldering time Condition Reflow Soldering Lead Solder Lead-free Solder 180 ~ 200C 120 ~ 150C 120 sec.

Although the recommended soldering conditions are specified in the above table, reflow or hand soldering at the lowest possible temperature is desirable for the LEDs. A rapid-rate process is not recommended for cooling the LEDs down from the peak temperature.

It is recommended that the User use the nitrogen reflow method. * Repairing should not be done after the LEDs have been soldered. When repairing is unavoidable, a double-head soldering iron should be used. It should be confirmed beforehand whether the characteristics of the LEDs will or will not be damaged by repairing. * Reflow soldering should not be done more than two times. * When soldering, do not put stress on the LEDs during heating. * After soldering, do not warp the circuit board. (5) Cleaning * It is recommended that isopropyl alcohol be used as a solvent for cleaning the LEDs. When using other solvents, it should be confirmed beforehand whether the solvents will dissolve the package and the resin or not. Freon solvents should not be used to clean the LEDs because of worldwide regulations. * Do not clean the LEDs by the ultrasonic. When it is absolutely necessary, the influence of ultrasonic cleaning on the LEDs depends on factors such as ultrasonic power and the assembled condition. Before cleaning, a pre-test should be done to confirm whether any damage to the LEDs will occur. -5- Nichia STSE-CC7044B <Cat.No.070606> (6) Static Electricity * Static electricity or surge voltage damages the LEDs. It is recommended that a wrist band or an anti-electrostatic glove be used when handling the LEDs. * 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 static-damaged LEDs by a light-on test or a VF test at a lower current (below 1mA is recommended). * Damaged LEDs will show some unusual characteristics such as the leak current remarkably increases, the forward voltage becomes lower, or the LEDs do not light at the low current. Criteria : (VF > 2.0V at IF=0.5mA) (7) Others * NSSW108 complies with RoHS Directive. * Care must be taken to ensure that the reverse voltage will not exceed the absolute maximum rating when using the LEDs with matrix drive. * The LED light output is strong enough to injure human eyes. Precautions must be taken to prevent looking directly at the LEDs with unaided eyes for more than a few seconds. * Flashing lights have been known to cause discomfort in people; you can prevent this by taking precautions during use. Also, people should be cautious when using equipment that has had LEDs incorporated into it. * 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 systems, automobiles, traffic control equipment, life support systems and safety devices). * User shall not reverse engineer by disassembling or analysis of the LEDs without having prior written consent from Nichia. When defective LEDs are found, the User shall inform Nichia directly before disassembling or analysis. * The formal specifications must be exchanged and signed by both parties before large volume purchase begins. * The appearance and specifications of the product may be modified for improvement without notice. -6- Nichia STSE-CC7044B <Cat.No.070606> ICI Chromaticity Diagram 0.9 520 530 0.8 540 510 550 0.7 560 0.6 570 500 0.5 580 y 590 0.4 600 bj2 610 620 bk7 bj7 bk2 bk6 a67 bj6 a57 a66 a52 a56 0.3 490 0.2 630 a62 480 0.1 470 460 0 0 0.1 0.2 0.3 0.4 0.5 x 1/2 Color Coordinates Measurement allowance is 0.005. -7- 0.6 0.7 0.8 50 20 10 5 3.0 2.0 1.0 0 0 20 40 60 80 100 120 Forward Current IFP (mA) Ambient Temperature vs. Forward Voltage Ambient Temperature vs. Relative Luminosity 5.0 2.0 4.6 4.2 IFP=60mA IFP=20mA IFP=5mA 3.8 3.4 3.0 2.6 2.2 -40 -20 0 20 40 60 80 100 Ambient Temperature Ta (C) Relative Luminosity (a.u.) -8- Forward Voltage VF (V) 1 2.0 2.5 3.0 3.5 4.0 4.5 5.0 Forward Voltage VF (V) Ta=25C 4.0 IFP=20mA 1.0 0.5 0.2 -40 -20 0 20 40 60 80 100 Ambient Temperature Ta (C) Allowable Forward Current IFP (mA) Relative Luminosity (a.u.)
