CAPACITOR TERMINATIONS AND SOLDERING
RECOMMENDATIONS
I. TERMINATION TYPES
Our capacitors are delivered with one of the following terminations (for
technical reasons, only a limited number of termination types are available in
certain cases). All our terminations are backward compatible.

Comment
non-magnetic (silver-palladium)
non-magnetic (pure tin over copper barrier)
lead-free (pure tin over nickel barrier)
condition. The vapor phase and IR reflow soldering are less aggressive,
inducing more restricted thermal shocks. This is the reason why they are
preferred to the wave soldering method for reliable applications. In all cases,
proper pre-heating is essential.
The circuit should be pre-heated at a typical rate of 1°C/s within 65°C to 100°C of
the maximum soldering temperature. While multilayer ceramic capacitors can
withstand the peak soldering temperatures for short durations, they should be
minimized whenever possible.
Above precaution given for SMD types are applicable for the implementation
of large bare chips (1515 and above). But in general, large bare chips above
2225 are not recommended to be mounted on epoxy printed board due to the
thermal expansion mismatch between ceramic capacitor body and epoxy. This
is the reason why leaded components will be preferred especially for reliable
applications.
For information, the typical thermal profiles of these three soldering processes
are given hereafter. These typical diagrams are only given as an aid to SMD
users in determining specific processes linked to their instrumentations and
to their own experience.
NB: reference documents are IEC 61760-1, CECC30000 and IEC68 standards.
Please, refer to this standard for more information.
NB:
• terminations type C recommended for non magnetic applications.
• termination type A available for non magnetic applications (for historical
reason, we have also another code, the code “P”, for the same type of
termination. The parts that were designed-in before 2005 might still have
a code “P” instead of “A” in the part numbering. But both codes correspond
to the same type of termination).
II. SPECIFICATIONS
Care must be taken when using particular terminations: if the terminations are
heated up above a particular temperature and/or for too long a period of time,
there is a risk of leaching (dissolution of the termination revealing the inner
electrodes).
The chart below gives the resistance to soldering heat per termination type,
based on a SAC387 solder bath at 260°C.

III. STANDARD SMD REQUIREMENTS
III.1. Soldering Recommendations
Regarding the soldering attachments, three methods are generally used: the
vapor phase soldering, the infrared reflow soldering and the wave soldering.
Unless particular skill about the use of the wave soldering, this method is not
recommended since the melted solder is directly in contact with the ceramic.
This can potentially crack the capacitor because the ceramic is sensible to the
thermal shocks. Moreover, this method needs to maintain the components
with an insulating resin which increases the thermo-mechanical strains
between the ceramic and the board both on soldering phase and operating
