Figure 16-1
below displays a cross-sectional area underneath the package. The cross section is of only one via. The solder Paste
template needs to be designed to allow at least 50% solder coverage. The thickness of the solder paste template should be 5mil.
It is recommended that “No Clean”, type 3 solder paste is used for mounting the part. Nitrogen purge is recommended during
reflow.
Figure 16-2a
is a plot of the solder mask pattern and
Figure 16-2b
displays an X-Ray image of the assembly (darker areas indicate
solder).
