Multilayer Ceramic Capacitor
– Soldering Methods
– Soldering Profile
– Manual Soldering
Since a multilayer ceramic chip capacitor comes into direct contact with melted solder during
soldering, it is exposed to potentially mechanical stress caused by the sudden temperature
change. The capacitor may also be subject to silver migration, and to contamination by the
flux. Because of these factors, soldering technique is critical.
* We recommend the reflow soldering method.
To avoid crack problem by sudden temperature change, follow the temperature profile in the
adjacent graph.
Manual soldering can pose a great risk of creating thermal cracks in chip capacitors. The hot
soldering iron tip comes into direct contact with the end terminations, and operator's carelessness
may cause the tip of the soldering iron to come into direct contact with the ceramic body of
the capacitor. Therefore the soldering iron must be handled carefully, and close attention must
be paid to the selection of the soldering iron tip and to temperature control of the tip.
