◆Soldering
･ Ceramic chip capacitors are susceptible to thermal shock when exposed to rapid or concentrated heating or rapid cooling.
･ Therefore, the soldering must be conducted with great care so as to prevent malfunction of the components due to excessive thermal
shock.
･ Preheating : Capacitors shall be preheated sufficiently, and the temperature difference between the capacitors and solder shall be within
130℃.
･ Cooling : The temperature difference between the capacitors and cleaning process shall not be greater than 100℃.

Caution
①The ideal condition is to have solder mass（fillet）controlled to 1/2 to 1/3 of the
thickness of a capacitor.
②Because excessive dwell times can adversely affect solderability, soldering duration shall
be kept as close to recommended times as possible. soldering for 2 times.
