Sn-Zn solder affects product reliability.
Please contact TDK in advance when utilize Sn-Zn solder.
The misalignment between the mounted positions of the capacitors and the land
patterns should be minimized. The tombstone phenomenon may occur especially
the capacitors are mounted
soldering.
(Refer to JEITA RCR-2335B Annex A (Informative) Recommendations to prevent the
tombstone phenomenon)
If cleaning condition is not suitable, it may damage the chip capacitors.

If an unsuitable cleaning fluid is used, flux residue or some foreign articles may

bring the same result as insufficient cleaning.
When ultrasonic cleaning is used, excessively high ultrasonic energy output
can affect the connection between the ceramic chip capacitor's body and the
terminal electrode. To avoid this, following is the recommended condition.
Terminal electrodes may corrode by Halogen in the flux.
Halogen in the flux may adhere on the surface of capacitors, and lower the
insulation resistance.
Water soluble flux has higher tendency to have above mentioned
problems (1) and (2).
