As a general guideline, Cree recommends that users follow the recommended soldering profile provided by the manufacturer of solder paste used. Note that this general guideline may not apply to all PCB designs and configurations of reflow soldering equipment. Profile Feature Lead-Based Solder Lead-Free Solder Average Ramp-Up Rate (Ts max to Tp) 3°C/second max. 3°C/second max. Preheat: Temperature Min (Ts min) 100°C 150°C Preheat: Temperature Max (Ts max) 150°C 200°C Preheat: Time (ts min to tsmax) 60-120 seconds 60-180 seconds Time Maintained Above: Temperature (T L) 183°C 217°C Time Maintained Above: Time (t L) 60-150 seconds 60-150 seconds Peak/Classification Temperature (Tp) 215°C 260°C Time Within 5°C of Actual Peak Temperature (tp) 10-30 seconds 20-40 seconds Ramp-Down Rate 6°C/second max. 6°C/second max Time 25°C to Peak Temperature 6 minutes max. 8 minutes max. Note: All temperatures refer to topside of the package, measured on the package body surface. Note: While the high reflow temperatures (above) have been approved, Cree’s best practice guideline for reflow is to use as low a temperature as possible during the reflow soldering process for these LEDs. |
