1.Temperature Dependent Characteristics
1. The electrical characteristics of the capacitor can change with temperature.
1-1. For capacitors having larger temperature dependency, the capacitance may change with temperature
changes. The following actions are recommended in order to insure suitable capacitance values.
(1) Select a suitable capacitance for the operating temperature range.
(2) The capacitance may change within the rated temperature.
When you use a high dielectric constant type capacitors in a circuit that needs a tight (narrow) capacitance
tolerance.
Example: a time constant circuit., please carefully consider the characteristics of these capacitors,
such as their aging, voltage, and temperature characteristics.
And check capacitors using your actual appliances at the intended environment and operating conditions.

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.
[Incorrect]
[Correct]
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.

4-1.Reflow Soldering
1. When sudden heat is applied to the components, the [Standard Conditions for Reflow Soldering]
mechanical strength of the components will decrease
because a sudden temperature change causes Infrared Reflow
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.
2. Solderability of Tin plating termination chips might be
deteriorated when a low temperature soldering profile where
the peak solder temperature is below the melting point of
Tin is used. Please confirm the Solderability of Tin plated
termination chips before use. Vapor Reflow
3. When components are immersed in solvent after mounting,
be sure to maintain the temperature difference (ΔT)
between the component and the solvent within the range
shown in the table 1.

soldering time must be within the range shown above.
4. Optimum Solder Amount for Reflow Soldering
4-1. Overly thick application of solder paste results in
a excessive solder fillet height.
This makes the chip more susceptible to mechanical
and thermal stress on the board and may cause
the chips to crack.
* GC□03: 1/3 of Chip Thickness min.
4-2. Too little solder paste results in a lack of adhesive in section
strength on the outer electrode, which may result in
chips breaking loose from the PCB.
4-3. Make sure the solder has been applied smoothly to the end surface to a height of 0.2mm* min.
Make sure not to impose any abnormal mechanical shocks to the PCB.

4-2.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.
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 support pin or specific jig, when inspecting the electrical performance of
a capacitor after mounting on the printed circuit board.
1-1. Avoid bending printed circuit board by the pressure of a test pin, etc.
The thrusting force of the test probe can flex the PCB, resulting in cracked chips or open solder joints.
Provide support pins on the back side of the PCB to prevent warping or flexing.
1-2. Avoid vibration of the board by shock when a test pin 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 is
caused by bending or twisting the board.
1-1. In cropping the board, the stress as shown right may cause the capacitor to crack.
Try not to apply this type of stress to a capacitor.
Bending Twisting
2. Check of the cropping method for the printed circuit board in advance.
2-1. Printed circuit board cropping shall be carried out by using a jig or an apparatus to prevent the
mechanical stress which can occur to the board.
(1) Example of a suitable jig
Recommended example: the board should be pushed as close to the near the cropping jig as possible
and from the back side of board in order to minimize the compressive stress applied to capacitor.
Not recommended example* when the board is pushed at a point far from the cropping jig and from
the front side of board as below, the capacitor may form a crack caused by the tensile stress applied
to capacitor.
Outline of jig
(2) Example of a suitable machine
An outline of a printed circuit board cropping machine is shown as follows. Along the lines with the
V-grooves on printed circuit board, the top and bottom blades are aligned to one another when
cropping the board.
