TI recommends using a Type 3 or finer solder paste
when mounting the MicrostarCSP. This paste offers
the following advantages:
It acts as a flux to aid wetting of the solder ball to
the PCB land.
The adhesive properties of the paste hold the
component in place during the reflow process.
Solder paste selection is normally driven by the
overall system-assembly requirements. In general,
the no clean compositions are preferred because
of the difficulty in cleaning below the mounted
components. Customers should check with the
solder-paste vendors regarding electrical issues

from residues left on the board.
TI recommends a pressure safety zone in mounting
the MicrostarCSP package. The recommended force
should be controlled to 5N maximum for static and
2.5N for impact.
The MicrostarCSP package solder ball is compatible
with lead and lead-free pastes. Example reflow
profiles for SnPb and Pb-free are shown in Figure 55
and Figure 56. Table 4 lists the profiles for SnPb and
Pb-free reflow.
TI recommends that the solder-paste manufacturer
temperature profile be used to optimize flux activity
