This varies according to the used solder alloy. • The Peak temperature (Tp) for the reflow profile, measured at top of the package. – For the user (board assembly process), Tp must not exceed Tc as shown in Table 2. For the IC suppier, the Tp is ≥Tc. WebFor example, when soldering a copper substrate with Sn63/Pb37, the peak temperature is generally in the range of 205° to 215°C. Too high of a reflow peak temperature can lead to excessive copper dissolution and intermetallic formation and damage to the flux vehicle. michael teachings king
