Table 16-1
Table 16-1.
Small packages may be subject to higher temperatures if they are reflowed in boards with larger
components. In this case, small packages may have to withstand temperatures of up to 235 C,
not 220 C (IR reflow).
Recommended package reflow conditions depend on package thickness and volume. See
Table
Table 16-2.
Notes:
A maximum of three reflow passes is allowed per component.
Average Ramp-up Rate (183 C to Peak)

1. The packages are qualified by Atmel by using IR reflow conditions, not convection or VPR.
2. By default, the package level 1 is qualified at 220 C (unless 235 C is stipulated).
3. The body temperature is the most important parameter but other profile parameters such as
total exposure time to hot temperature or heating rate may also influence component reliability.
