Note 2: Time within 5 C of actual peak temperature (tp) specied for the reow proles is a "supplier" minimum and a "user" maximum. Note 1: Package volume excludes external terminals (balls, bumps, lands, leads) and/or non-integral heat sinks. Note 2: The maximum component temperature reached during reow depends on package thickness and volume. The use of convection reow processess reduces the thermal gradients between packages. However, thermal gradients due to differences in thermal mass of SMD packages may still exist. Note 3: Components intended for use in "leadfree" assembly process shall be evaluated using the "lead-free" peak temperature and proles dened in Table 1, 2 and reow prole whether or not lead-free. * Tolerance: The device manufacturer/supplier shall assure process compatibility up to and including the stated classication temperature at the rated MSL level.
