Soldering (1) Lead free soldering 1) Following soldering paste is recommended Melting temperature: 216 ~ 220 C. Composition: Sn / 3.5Ag / 0.75Cu 2) The temperature profile at the top surface of the parts is recommended as shown below. T em p era tu re 3) It is requested that products should be handled after their temperature has dropped down to the normal room temperature 4 °C/sec. Max 4 °C/sec. Max 260 °C Max 3sec. Max 220 °C 160 ~ 180 °C 60 ~ 70sec 140sec Time 9-2. Washing (1) When washing after soldering is needed, following conditions are requested. a) Washing solvent: Pure Water b) Temperature, time: 50 C or less × 30 seconds max. or 30 C or less × 3 minutes max. c) Ultrasonic washing: 300W or less 9-3. Other directions (1) It is requested to avoid any stress added to the resin portion while it is heated. (2) It is requested to avoid any friction by sharp metal nail etc. to the resin portion. (3) For outdoor use, necessary measures should be taken to prevent water, moisture and salt air damage. This product is NOT designed with following conditions in mind. In water, oil, medicament, organic solvent and dust-laden environment. Symbol Name CITILED CL-L270-MU1L2-A1 CITIZEN ELECTRONICS CO.,LTD. JAPAN Ref.CE-P1401 08/11 DATA SHEET 10 / 12 10. Designing precautions (1) The current limiting resistor should be placed in the circuit so that is driven within its rating. Also avoid reverse voltage (over-current) applied instantaneously when ON or OFF. (2) When pulse driving current is applied, average current consumption should be within the rating. Also avoid reverse voltage applied when put off. (3) Recommended soldering pattern <For reflow soldering> Unit : mm Mountability and solderability need to be optimized with actual conditions such as amount of solder, reflow temperature applied in the process. (4) When assembling the circuit board into the finished products, care must be taken to avoid the component parts from touching other parts. (5) When using multiple LEDs, it is required to connect a current limiting resistor on each path which the current flows to the LEDs.

Eye Safety - The International Electrical Commission (IEC) published in 2006 IEC 62471 ”2006 Photobiological safety oflamps and lamp systems ” which includes LEDs within its scope. When sorting single LEDs according to IEC 62471, most LEDs can be classified as belonging to either Exempt Group or Risk Group 1. - Optical characteristics of LEDs such as radiant flux, spectrum and light distribution are factors that affect the risk group determination of the LED, and especially a high-power LED, that emits light containing blue wavelengths, may have properties equivalent to those of Risk Group 2. - Great care should be taken when directly viewing an LED that is driven at high current, has multiple uses as a module or when focusing the light with optical instruments, as these actions may greatly increase the hazard to your eyes. - In addition, LED sources that were included within the scope of IEC 60825-1 / Edition 1.2 “laser safety standard”, published 2001 were removed from the scope of the IEC 60825-1 / Edition 2.0 revised 2007. - However, keep in 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. 7.
