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 re ow depends on package
thickness and volume. The use of convection
re ow processess reduces the thermal gradients
between packages. However, thermal gradients
due to differences in thermal mass of SMD pack-
ages may still exist.
Note 3: Components intended for use in “lead-
free” assembly process shall be evaluated using
the “lead-free” peak temperature and pro les
de ned in Table 1, 2 and re ow pro le whether
or not lead-free.
