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.

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. in section
4-2. Too little solder paste results in a lack of adhesive
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.Flow Soldering
1. When sudden heat is applied to the components, the
mechanical strength of the components will decrease [Standard Conditions for Flow Soldering]
because a sudden temperature change causes
deformation inside the components. In order to prevent
mechanical damage in the components, preheating should
be required for both of the components and the PCB board.
Preheating conditions are shown in table 2. It is required to
keep temperature differential between the solder and
the components surface (ΔT) as small as possible.
2. Excessively long soldering time or high soldering
temperature can result in leaching of the outer electrodes,
causing poor adhesion or a reduction in capacitance value
due to loss of contact between electrodes and end termination.
3. When components are immersed in solvent after mounting, [Allowable Soldering Temperature and Time]
be sure to maintain the temperature difference (ΔT)
between the component and solvent within the range
shown in the table 2.
4. Do not apply flow soldering to GQM22 Series.

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.
Table 3
*Applicable for both Pb-Sn and Lead Free Solder. Pb-Sn Solder: Sn-37Pb
Lead Free Solder: Sn-3.0Ag-0.5Cu
4. Optimum Solder amount when re-working with a Soldering lron
4-1. In case of sizes smaller than 0603, (GQM18), 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, (GQM21/22), the top of
the solder fillet should be lower than 2/3's of the thickness in section
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.

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.
The misalignment of the position between top and bottom blades may cause the capacitor to crack.
