(recommended condition in a case of lead-free solder condition) - no external force shall be applied to resin part during soldering. - regarding soldering correction, above conditions shall be used. - contacts number of soldering bit should be within twice for each terminal as a correction. * citizen electronics cannot guarantee if usage exceeds this recommended conditions. data sheet when a minimum current is applied, led dice may look different in their brightness due to a minimum current value of lighting of all dice is 60ma. taken into consideration, depending on ambient temperature (ta). - next process of soldering should be carried out after the product has returned to ambient - for soldering correction the individual difference of the led element, and it is not a failed product. ambient temperature conditions or power dissipation. thus, drive conditions should be in assembled status. - factors responsible for an increase in temperature include heat generation attributed to please ensure that heat generation is not in excess of the absolute maximum rating. (refer to 4-1 performance) - soldering shall be implemented using a soldering bit of 40w or less with a temperature ref.ce-p1182 05/11 r1(0711) 10/11 12. 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. symbol citiled name - this product complies with rohs directives.
