WebTherefore, a peak temperature of 210˚ to 220˚C will be suitable for tin/lead, but inadequate for lead-free BGA balls with melting point of 217˚ to 221˚C. A peak temperature of 226˚ to 228˚C with 45 to 60 seconds time above liquidus (TAL) will be sufficient to reflow lead-free BGAs without damaging all tin/lead components on the same board. Web3 Reflow Profile for Lead-Free Soldering When reflowing TI power modules, the peak reflow rating of the device must be observed and applied. A reflow profile that meets the temperature and time requirements defined in J-STD-020D.1 is shown in Figure 3. Figure 3 illustrates the key temperature and times associated with the different reflow oven ... The third section, the reflow zone, is also referred to as the “time above reflow” or “temperature above liquidus” (TAL), and is the part of the process where the maximum temperature is reached. An important consideration is peak temperature, which is the maximum allowable temperature of the entire process. A common peak temperature is 20–40 °C above liquidus.
