âSoldering
ï½¥ Ceramic chip capacitors are susceptible to thermal shock when exposed to rapid or concentrated heating or rapid cooling.
ï½¥ Therefore, the soldering must be conducted with great care so as to prevent malfunction of the components due to excessive thermal
shock.
ï½¥ Preheating : Capacitors shall be preheated sufficiently, and the temperature difference between the capacitors and solder shall be within
100 to 130â.
ï½¥ Cooling : The temperature difference between the capacitors and cleaning process shall not be greater than 100â.

â The ideal condition is to have solder massï¼filletï¼controlled to 1/2 to 1/3 of the

â¡Because excessive dwell times can adversely affect solderability, soldering duration shall
be kept as close to recommended times as possible.

5. Cleaning
Precautions
Technical
considerations
âCleaning conditions
1. When PCBs are cleaned after capacitors mounting, please select the appropriate cleaning solution in accordance with the intended use
of the cleaning. ï¼e.g. to remove soldering flux or other materials from the production process.ï¼
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 ï¼especially insulation resistanceï¼.
2. Inappropriate cleaning conditionsï¼ insufficient or excessive cleaningï¼ may adversely affect the performance of
the capacitors.
In the case of ultrasonic cleaning, too much power output can cause excessive vibration of PCBs which may lead
to the
cracking of capacitors or the soldered portion, or decrease the terminal electrodes' strength. Therefore, the following conditions shall
be carefully checked;
Ultrasonic output :
20 W/â or less
Ultrasonic frequency : 40 kHz or less
Ultrasonic washing period : 5 min. or less
