To prevent in adequate exposure of the radiation, wear protective glasses. 2. Remarks concerning optical radiation safety* Up to maximum forward current, at continuous operation, this LED may be classified as LED product Class 1 , according to standard IEC 60825-1:A2. Class 1 products are safe to eyes and skin under reasonably predictable conditions. This implicates a direct observation of the light beam by means of optical instruments. *Note: Safety classification of an optical component mainly depends on the intended application and the way the component is being used. Furthermore, all statements made to classification are based on calculations and are only valid for this LED "as it is", and at continuous operation. Using pulsed current or altering the light beam with additional optics may lead to different safety classifications. Therefore these remarks should be taken as recommendation and guideline only. 07.04.2011 ELD-810-345 3 of 4 3. Lead Forming • When forming leads, the leads should be bent at a point at least 3 mm from the base of the lead. 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 mounted the LEDs onto the printed circuit board, the holes on the circuit board should be exactly aligned with the leads of LEDs. If the LEDs are mounted with stress at the leads, it causes deterioration of the lead and it will degrade the LEDs. 4. Soldering Conditions • Solder the LEDs no closer than 3 mm from the base of the lead. • DO NOT apply any stress to the lead particularly when heat. • The LEDs must not be reposition after soldering. • After soldering the LEDs, the lead should be protected from mechanical shock or vibration until the LEDs return to room temperature. • When it is necessary to clamp the LEDs to prevent soldering failure, it is important to minimize the mechanical stress on the LEDs. • Cut the LED leads at room temperature. Cutting the leads at high temperature may cause the failure of the LEDs. 5. Static Electricity • The LEDs are very sensitive to Static Electricity and surge voltage. So 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 grounded properly. It is recommended that precautions should be taken against surge voltage to the equipment that mounts the LEDs. 07.04.2011 ELD-810-345 4 of 4
