［Reflow soldering］
【Recommended conditions for eutectic
soldering】
【Recommended condition for Pb-free
soldering】
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.
［Wave soldering］
【Recommended conditions for eutectic
soldering】
【Recommended condition for Pb-free
soldering】
Caution
①Wave soldering must not be applied to capacitors designated as for reflow soldering only.
［Hand soldering］
【Recommended conditions for eutectic
soldering】
【Recommended condition for Pb-free
soldering】

5. Cleaning
Precautions
◆Cleaning conditions
1. When PCBs are cleaned after capacitors mounting, please select the appropriate cleaning solution in accordance with the intended use
of the cleaning. （e.g. to remove soldering flux or other materials from the production process.）
2. Cleaning condition shall be determined after it is verified by using actual cleaning machine that the cleaning process does not affect
capacitor's characteristics.
1. The use of inappropriate cleaning solutions can cause foreign substances such as flux residue to adhere to capacitors or deteriorate
their outer coating, resulting in a degradation of the capacitor's electrical properties （especially insulation resistance）.
2. Inappropriate cleaning conditions（ insufficient or excessive cleaning） may adversely affect the performance of
In the case of ultrasonic cleaning, too much power output can cause excessive vibration of PCBs which may lead
