MLCC is an electronic part that temporarily stores an electrical charge and the
most prevalent type of capacitor today. New technologies have enabled the
MLCC manufacturers to follow the trend dictated by smaller and
smaller electronic devices such as Cellular telephones, Computers, DSC, DVC
Nominal capacitance is identified by 3 digits.

● STORAGE CONDITION
▶ Storage Environment
The electrical characteristics of MLCCs were degraded by the environment of high temperature or
humidity. Therefore, the MLCCs shall be stored in the am bient temperature and the relative humidity
of less than 40℃ and 70%, respectively.
Guaranteed storage period is within 6 months from the outgoing date of delivery.
▶ Corrosive Gases
Since the solderability of the end termination in MLCC was degraded by a chemical atmosphere
such as chlorine, acid or sulfide gases, MLCCs must be avoid from these gases.
▶ Temperature Fluctuations
Since dew condensation may occur by the differences in temperature when the MLCCs are taken
out of storage, it is important to maintain the temperature-controlled environment
.
● DESIGN OF LAND PATTERN
When designing printed circuit boards, the shape and size of the lands must allow for the proper
amount of solder on the capacitor.
The amount of solder at the end terminations has a direct effect on the crack.
The crack in MLCC will be easily occurred by the tensile stress which was due to too much amount
of solder. In contrast, if too little solder is applied, the termination strength will be insufficiently.
Use the following illustrations as guidelines for proper land design.
Recommendation of Land Shape and Size.

● ADHESIVES
When flow soldering the MLCCs, apply the adhesive in accordance with the following conditions.
▶ Requirement s for Adhesives
They must have enough adhesion, so that, the chips will not fall off or move during the handling of the
circuit board.
They must maintain their adhesive strength when exposed to soldering temperature.
They should not spread or run when applied to the circuit board.
They should harden quickly. They should not corrode the circuit board or chip material.
They should be a good insulator. They should be non-toxic, and not produce harmful gases, nor be
harmful when touched.
▶ Application Method
It is important to use the proper amount of adhesive. Too little and much adhesive will cause poor
adhesion and overflow into the land, respectively.

▶ Adhesive hardening Characteristics
To prevent oxidation of the terminations, the adhesive must harden at 160℃ or less, within 2 minutes
.
or less
● MOUNTING
▶ Mounting Head Pressure
Excessive pressure will cause crack to MLCCs. The pressure of nozzle will be 300g maximum during
mounting.
Page 19
▶ Bending Stress
When double-sided circuit boards are used, MLCCs first are mounted and soldered onto one side of the
board. When the MLCCs are mounted onto the other side,
it is important to support the board as shown in the illustration. If the circuit board is not supported,
the crack occur to the ready-installed MLCCs by the bending stress.

General Capacitors
▶ Manual Soldering
Manual soldering can pose a great risk of creating thermal cracks in chip capacitors.
The hot soldering iron tip comes into direct contact with the end terminations, and operator's
carelessness may cause the tip of the soldering iron to come into direct contact with the ceramic
body of the capacitor.
Therefore the soldering iron must be handled carefully, and close attention must be paid
to the selection of the soldering iron tip and to temperature control of the tip.

Page 20
▶ Cooling
Natural cooling using air is recommended. If the chips are dipped into solvent for cleaning, the
temperature difference(△T) must be less than 100℃
▶ Cleaning
If rosin flux is used, cleaning usually is unnecessary. When strongly activated flux is used, chlorine in
the flux may dissolve into some types of cleaning fluids, thereby affecting the chip capacitors. This
means that the cleaning fluid must be carefully selected, and should always be new.
▶ Notes for Separating Multiple, Shared PC Boards.
A multi-PC board is separated into many individual circuit boards after soldering has been completed.
If the board is bent or distorted at the time of separation, cracks may occur in the chip capacitors.
Carefully choose a separation method that minimizes the bending often circuit board.
