◆Pattern configurations （Capacitor layout on PCBs）
1-1. The following is examples of good and bad capacitor layouts ; capacitors shall be located to minimize any
stresses from board warp or deflection.
possible mechanical
Items
Deflection of board
Not recommended
Recommended
Place the product at a right
angle to the direction of the
anticipated mechanical
stress.
1-2. The amount of mechanical stresses given will vary depending on capacitor layout. Please refer to diagram below.

1-3. When PCB is split, the amount of mechanical stress on the capacitors can vary according to the method used. The following methods
are listed in order from least stressful to most stressful: push-back, slit, V-grooving, and perforation. Thus, please consider the PCB,
split methods as well as chip location.
3. Mounting
◆Adjustment of mounting machine
1. When capacitors are mounted on PCB, excessive impact load shall not be imposed on them.
2. Maintenance and inspection of mounting machines shall be conducted periodically.
Precautions
◆Selection of Adhesives
1. When chips are attached on PCBs with adhesives prior to soldering, it may cause capacitor characteristics degradation unless the
following factors are appropriately checked : size of land patterns, type of adhesive, amount applied, hardening temperature and
hardening period. Therefore, please contact us for further information.
