motion having a total amplitude of 1.5mm, the frequency
being varied uniformly between the approximate limits of 10
and 55Hz. The frequency range, from 10 to 55Hz and return
to 10Hz, should be traversed in approximately 1 minute. This
motion should be applied for a period of 2 hours in each 3
mutually perpendicular directions(total of 6 hours).
Solder the capacitor on the test jig (glass epoxy board)
shown in Fig.1 using an eutectic solder. Then apply a force
in the direction shown in Fig 2 for 5+/-1 sec. The soldering
should be done by the reflow method and should be
conducted with care so that the soldering is uniform and free
of defects such as heat shock.

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.

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.

2.Adhesive Application
1. Thin or insufficient adhesive can cause the chips to loosen or become disconnected during flow soldering.
The amount of adhesive must be more than dimension c, shown in the drawing at right, to obtain
the correct bonding strength.
The chip's electrode thickness and land thickness must also be taken into consideration.

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.
［As a Single Chip］
4. Do not use water-soluble flux.
(*Water-soluble flux can be defined as non roｓin type flux
including wash-type flux and non-wash-type flux.)

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.
