13 Recommended Soldering Profile The LEDs can be soldered using the parameters listed below. As a general guideline, the users are suggested to follow the recommended soldering profile provided by the manufacturer of the solder paste. Although the recommended soldering conditions are specified in the list, reflow soldering at the lowest possible temperature is advised for the LEDs.

14 Thermal Design Thermal design of the end product is important. The thermal resistance between the junction and the solder point (RΘ J-P ) and the end product should be designed to minimize the thermal resistance from the solder point to ambient in order to optimize the emitter life and optical characteristics. The maximum operation current is determined by the plot of Allowable Forward Current vs. Ambient Temperature Forward Currennt (ma) Rja=40 Rja=30 Rja=20 Rja= Ambient Temperature ( ) The junction temperature can be correlated to the thermal resistance between the junction and ambient (Rja) by the following equation. Tj=Ta + Rja*W Tj: LED junction temperature Ta: Ambient temperature Rja: Thermal resistance between the junction and ambient W: Input power ( I F *V F ) 13
