Table 29-1
Table 29-1.
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 29-2
Table 29-2.

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
4. A maximum of three reflow passes is allowed per component.
total exposure time to hot temperature or heating rate may also influence component
reliability.
