Note 1:
All temperatures refer
to topside of the package,
measured on the package
body surface.
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 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 proles
dened in Table 1, 2 and reow prole whether
or not lead-free.
