We recommend to use AuSn, SAC and Ag paste for vertical silicon capacitors.
Sn63 and SnPb can be used for die bonding, but we don't recommend them because of effect for environment.
If you would like to know further details of assembly for vertical silicon capacitors or other types silicon capacitors (e.g. SMD, Embedded), please refer to the following assembly notes.
