Caution
4-3. Correction of Soldered Portion
1. For the shape of the soldering iron tip, refer to the figure
on the right.
2. Regarding the type of solder, use a wire diameter of
φ0.5mm or less (rosin core wire solder).
3. Apply the tip of the soldering iron against the lower end
of the metal terminal.
(1) In order to prevent cracking caused by sudden heating
of the ceramic device, do not touch the ceramic base
directly.
(2) In order to prevent deviations and dislocating of the
chip, do not touch the junction of the chip and the metal
terminal, and the metal portion on the outside directly.
4. The amount of solder for corrections by soldering iron,
should be lower than the height of the lower side of the chip.

5. Washing
Excessive ultrasonic oscillation during cleaning can cause the PCBs to resonate, resulting in cracked chips or broken
solder joints. Take note not to vibrate PCBs.
6. Electrical Test on Printed Circuit Board
1. Confirm position of the backup pin or specific jig, when inspecting the electrical performance of a capacitor after
mounting on the printed circuit board.
1-1. Avoid bending the printed circuit board by the pressure of a test-probe, etc. The thrusting force of the test probe can
flex the PCB, resulting in cracked chips or open solder joints. Provide backup pins on the back side of the PCB
to prevent warping or flexing. Install backup pins as close to the capacitor as possible.
1-2. Avoid vibration of the board by shock when a test-probe contacts a printed circuit board.

7. Printed Circuit Board Cropping
1. After mounting a capacitor on a printed circuit board, do not apply any stress to the capacitor that causes bending
or twisting the board.
1-1. In cropping the board, the stress as shown at right may cause the capacitor to crack. Cracked capacitors may cause
deterioration of the insulation resistance, and result in a short. Avoid this type of stress to a capacitor.
