Assembly
See Table 2
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 refl ow depends on package
thickness and volume. The use of convection
refl 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 profi les
defi ned in Table 1, 2 and refl ow profi le whether
or not lead-free.
