2.Information before mounting
1. Do Not re-use capacitors that were removed from the equipment.
2. Confirm capacitance characteristics under actual applied voltage.
3. Confirm the mechanical stress under actual process and equipment use.
4. Confirm the rated capacitance, rated voltage and other electrical characteristics before assembly.
5. Prior to use, confirm the Solderability for the capacitors that were in long-term storage.
6. Prior to measuring capacitance, carry out a heat treatment for capacitors that were in long-term storage.
7.The use of Sn-Zn based solder will deteriorate the reliability of the MLCC.
Please contact our sales representative or product engineers on the use of Sn-Zn based solder in advance.
3.Maintenance of the Mounting (pick and place) Machine
1. Make sure that the following excessive forces are not applied to the capacitors.
1-1. In mounting the capacitors on the printed circuit board, any bending force against them shall be kept
to a minimum to prevent them from any bending damage or cracking. Please take into account the
following precautions and recommendations for use in your process.
(1) Adjust the lowest position of the pickup nozzle so as not to bend the printed circuit board.
(2) Adjust the nozzle pressure within a static load of 1N to 3N during mounting.

2.Dirt particles and dust accumulated between the suction nozzle and the cylinder inner wall prevent
the nozzle from moving smoothly. This imposes greater force upon the chip during mounting,
causing cracked chips. Also the locating claw, when worn out, imposes uneven forces on the chip
when positioning, causing cracked chips. The suction nozzle and the locating claw must be maintained,
checked and replaced periodically.

Caution
4-1.Reflow Soldering
1. When sudden heat is applied to the components, the
mechanical strength of the components will decrease
because a sudden temperature change causes
deformation inside the components. In order to prevent
mechanical damage to the components, preheating is
required for both the components and the PCB board.
Preheating conditions are shown in table 1. It is required to
keep the temperature differential between the solder and
the components surface (ΔT) as small as possible.

Caution
4-3.Correction with a Soldering Iron
1. When sudden heat is applied to the components when using a soldering iron, the mechanical strength of
the components will decrease because the extreme temperature change can cause deformations inside the
components. In order to prevent mechanical damage to the components, preheating is required for both
the components and the PCB board. Preheating conditions, (The "Temperature of the Soldering Iron tip",
"Preheating Temperature", "Temperature Differential" between the iron tip and the components and the
PCB), should be within the conditions of table 3. It is required to keep the temperature differential
between the soldering Iron and the component surfaces (ΔT) as small as possible.
2. After soldering, do not allow the component/PCB to rapidly cool down.
3. The operating time for the re-working should be as short as possible. When re-working time is
too long, it may cause solder leaching, and that will cause a reduction in the adhesive
strength of the terminations.

4. Optimum Solder amount when re-working with a Soldering lron
4-1. In case of sizes smaller than 0603, (GR□03/15/18),
the top of the solder fillet should be lower than 2/3's
of the thickness of the component or 0.5mm whichever
is smaller. In case of 0805 and larger sizes, (GR□21/
31/32/43/55), the top of the solder fillet should be lower
than 2/3's of the thickness of the component. If the
solder amount is excessive, the risk of cracking is higher
during board bending or under any other stressful condition.

4-2. A Soldering iron with a tip of ø3mm or smaller should be used. It is also necessary to keep
the soldering iron from touching the components during the re-work.
4-3. Solder wire with ø0.5mm or smaller is required for soldering.
4-4.Leaded Component Insertion
1. If the PCB is flexed when leaded components (such as transformers and ICs) are being mounted,
chips may crack and solder joints may break.
Before mounting leaded components, support the PCB using backup pins or special jigs to prevent warping.

Notice
■ Rating
1.Operating Temperature
1. The operating temperature limit depends on the capacitor.
1-1.Do not apply temperatures exceeding the upper operating temperature.
It is necessary to select a capacitor with a suitable rated temperature which will cover the operating
temperature range.
Also it is necessary to consider the temperature distribution in equipment and the seasonal temperature
variable factor.
1-2.Consider the self-heating of the capacitor
The surface temperature of the capacitor shall be the upper operating temperature or less when
including the self-heating factors.
2.Atmosphere surroundings (gaseous and liquid)
1. Restriction on the operating environment of capacitors.
1-1. The capacitor, when used in the above, unsuitable, operating environments may deteriorate
due to the corrosion of the terminations and the penetration of moisture into the capacitor.
1-2. The same phenomenon as the above may occur when the electrodes or terminals of the capacitor are
subject to moisture condensation.
1-3. The deterioration of characteristics and insulation resistance due to the oxidization or corrosion of
terminal electrodes may result in breakdown when the capacitor is exposed to corrosive or
volatile gases or solvents for long periods of time.
3.Piezo-electric Phenomenon
1. When using high dielectric constant type capacitors in AC or pulse circuits, the capacitor itself vibrates
at specific frequencies and noise may be generated.
Moreover, when the mechanical vibration or shock is added to capacitor, noise may occur.

■ Soldering and Mounting
1.PCB Design
1. Notice for Pattern Forms
1-1. Unlike leaded components, chip components are susceptible to flexing stresses since they are mounted
directly on the substrate.
They are also more sensitive to mechanical and thermal stresses than leaded components.
Excess solder fillet height can multiply these stresses and cause chip cracking. When designing substrates,
take land patterns and dimensions into consideration to eliminate the possibility of excess solder fillet
height.
1-2.There is a possibility of chip crack caused by PCB expansion/contraction with heat.
Because stress for chip is different depend on PCB material and structure.Especially metal PCB
such as alumina has a greater risk of chip crack because of large difference of thermal expansion coefficient.
In case of chip below 0402 size, there is also the same possibility of crack with a single-layered glass epoxy
board.

3.Adhesive Curing
1. Insufficient curing of the adhesive can cause chips to disconnect during flow soldering and causes
deterioration in the insulation resistance between the outer electrodes due to moisture absorption.
Control curing temperature and time in order to prevent insufficient hardening.
4.Flux Application
1. An excessive amount of flux generates a large quantity of flux gas, which can cause a deterioration
of Solderability.
So apply flux thinly and evenly throughout. (A foaming system is generally used for flow soldering).
2. Flux containing too a high percentage of halide may cause corrosion of the outer electrodes unless
there is sufficient cleaning. Use flux with a halide content of 0.2% max.
3. Do not use strong acidic flux.

Notice
6.Washing
1. Please evaluate a capacitor by actual cleaning equipment and condition surely
for confirming the quality and select the applicable solvent.
2. Unsuitable cleaning solvent may leave residual flux, other foreign substances, causing deterioration of
electrical characteristics and the reliability of the capacitors.
3. Select the proper cleaning conditions.
3-1. Improper cleaning conditions (excessive or insufficient) may result in the deterioration of the
performance of the capacitors.
7.Coating
1. A crack may be caused in the capacitor due to the stress of the thermal contraction of the resin during
curing process.
The stress is affected by the amount of resin and curing contraction.
Select a resin with small curing contraction.
The difference in the thermal expansion coefficient between a coating resin or a molding resin and
capacitor may cause the destruction and deterioration of the capacitor such as a crack or peeling, and
lead to the deterioration of insulation resistance or dielectric breakdown.
Select a resin for which the thermal expansion coefficient is as close to that of capacitor as possible.
A silicone resin can be used as an under-coating to buffer against the stress.
2. Select a resin that is less hygroscopic.
Using hygroscopic resins under high humidity conditions may cause the deterioration of the
insulation resistance of a capacitor.
An epoxy resin can be used as a less hygroscopic resin.
■ Others
1.Transportation
1. The performance of a capacitor may be affected by the conditions during transportation.
1-1. The capacitors shall be protected against excessive temperature, humidity and mechanical force
during transportation.
(1) Climatic condition
－ low air temperature：－40℃
－ change of temperature air/air：－25℃/＋25℃
－ low air pressure：30 kPa
－ change of air pressure：6 kPa/min
(2) Mechanical condition
Transportation shall be done in such a way that the boxes are not deformed and forces are not directly
passed on to the inner packaging.
1-2. Do not apply excessive vibration, shock, and pressure to the capacitor.
(1) When excessive mechanical shock or pressure is applied to a capacitor, chipping or cracking may
occur in the ceramic body of the capacitor.
(2) When a sharp edge of an air driver, a soldering iron, tweezers, a chassis, etc. impacts strongly on the
surface of capacitor, the capacitor may crack and short-circuit.
1-3. Do not use a capacitor to which excessive shock was applied by dropping etc.
The capacitor dropped accidentally during processing may be damaged.
