58 / 72 page  11.6 Soldering and Reflow Condition • Heating method: Conventional convection or IR convection • Temperature measurement: Thermocouple d = 0.1 mm to 0.2 mm CA (K) or CC (T) at soldering portion or equivalent method • Solder paste composition: SAC305 • Allowable reflow soldering times: 2 times based on the reflow soldering profile (see Figure 11-1) • Temperature profile: Reflow soldering will be done according to the temperature profile (see Figure 11-1) • Peak temperature: 260°C Figure 11-1. Temperature Profile for Evaluation of Solder Heat Resistance of a Component (at Solder Joint) Table 11-1. Temperature Profile Profile Elements Convection or IR(1) Peak temperature range 235 to 240°C typical (260°C maximum) Pre-heat / soaking (150 to 200°C) 60 to 120 seconds Time above melting point 60 to 90 seconds Time with 5°C to peak 30 seconds maximum Ramp up < 3°C / second Ramp down < -6°C / second (1) For details, refer to the solder paste manufacturer's recommendation. Note TI does not recommend the use of conformal coating or similar material on the SimpleLink™ module. This coating can lead to localized stress on the solder connections inside the module and impact the module reliability. Use caution during the module assembly process to the final PCB to avoid the presence of foreign material inside the module.
