ꢀꢀꢀ⑨Data-processing equipmentꢀ⑩Application of similar complexity and/or reliability requirements to the applications listed in the above.

■Storage and Operation condition

1. The performance of chip multilayer ceramic capacitors (henceforth just "capacitors”) may be affected by the storage conditions. Please use them promptly after delivery.

1-1. Maintain appropriate storage for the capacitors using the following conditions:

ꢀRoom Temperature of 5℃ to 40℃ and a Relative Humidity of 20% to 70%.

High temperature and humidity conditions and/or prolonged storage may cause deterioration of the packaging materials.

If more than six months have elapsed since delivery, check packaging, mounting, etc. before use.

In addition, this may cause oxidation of the electrodes. If more than one year has elapsed since delivery, also check the solderability before use.

ꢀ1-2. Corrosive gas can react with the termination (external) electrodes or lead wires of capacitors, and result in poor solderability.

Do not store the capacitors in an atmosphere consisting of corrosive gas (e.g.,hydrogen sulfide, sulfur dioxide, chlorine, ammonia gas etc.).

1-3. Due to moisture condensation caused by rapid humidity changes, or the photochemical change caused by direct sunlight on the terminal electrodes

and/or the resin/epoxy coatings, the solderability and electrical performance may deteriorate.

Do not store capacitors under direct sunlight or in high huimidity conditions.

■Rating

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 ensure 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 capacitor in a circuit that needs a tight (narrow) capacitance tolerance (e.g., a time-constant circuit),

please carefully consider the temperature characteristics, and carefully confirm the various characteristics in actual use conditions and the actual system.

■Soldering and Mounting

1.Mounting Position

1. Confirm the best mounting position and direction that minimizes the stress imposed on the capacitor during flexing or bending the printed circuit board.

1-1.Choose a mounting position that minimizes the stress imposed on the chip during flexing or bending of the board.

ꢀ

[ Component Direction ]

Locate chip horizontal to the

direction in which stress acts.

(Bad Example)

(Good Example)

[ Chip Mounting Close to Board Separation Point ]

It is effective to implement the following measures, to reduce stress in separating the board.

It is best to implement all of the following three measures; however, implement as many measures as possible to reduce stress.

Contents of Measures

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 of 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.

GRM1885C2A331JA01-01A

3.Maintenance of the Mounting (pick and place) Machine

1. Make sure that the following excessive forces are not applied to the capacitors.

ꢀCheck the mounting in the actual device under actual use conditions ahead of time.

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 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.

[Incorrect]

Suction Nozzle

Board Guide

[Correct]

Support Pin

2. Dirt particles and dust accumulated in the suction nozzle and suction mechanism prevent the nozzle from moving smoothly.

This creates excessive force on the capacitor 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.

GRM1885C2A331JA01-01A

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.

3. When a capacitor is mounted at a temperature lower than the peak reflow temperature recommended by the solder manufacturer, the following quality problems can occur.

Consider factors such as the placement of peripheral components and the reflow temperature setting to prevent the capacitor’s reflow temperature from dropping below the peak temperature specified.

Be sure to evaluate the mounting situation beforehand and verify that none of the following problems occur.

･Drop in solder wettability

･Solder voids

･Possible occurrence of whiskering

･Drop in bonding strength

･Drop in self-alignment properties

･Possible occurrence of tombstones and/or shifting on the land patterns of the circuit board

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.

4-2. Too little solder paste results in a lack of adhesive strength on the termination, which may result in chips breaking loose from the PCB.

4-3. Please confirm that solder has been applied smoothly to the termination.

4-3.Correction of Soldered Portion

ꢀWhen sudden heat is applied to the capacitor, distortion caused by the large temperature difference occurs internally, and can be the cause of cracks.

Capacitors also tend to be affected by mechanical and thermal stress depending on the board preheating temperature or the soldering fillet shape, and can be the cause of cracks.

Please refer to "1. PCB Design" or "3. Optimum solder amount" for the solder amount and the fillet shapes.

1. Correction with a Soldering Iron

ꢀ1-1. In order to reduce damage to the capacitor, be sure to preheat the capacitor and the mounting board.

Preheat to the temperature range shown in Table 3. A hot plate, hot air type preheater, etc. can be used for preheating.

1-2. After soldering, do not allow the component/PCB to cool down rapidly.

1-3. Perform the corrections with a soldering iron as quickly as possible. If the soldering iron is applied too long, there is a possibility of

causing solder leaching on the terminal electrodes, which will cause deterioration of the adhesive strength and other problems.

2. Correction with Spot Heater

ꢀCompared to local heating with a soldering iron, hot air heating by a spot heater heats the overall component and board,

therefore, it tends to lessen the thermal shock. In the case of a high density mounted board, a spot heater can also prevent concerns

of the soldering iron making direct contact with the component.

2-1. If the distance from the hot air outlet of the spot heater to the component is too close, cracks may occur due to thermal shock.

To prevent this problem, follow the conditions shown in Table 4.

2-2. In order to create an appropriate solder fillet shape, it is recommended that hot air be applied at the angle shown in Figure 1.

5.Washing

Excessive ultrasonic oscillation during cleaning can cause the PCBs to resonate, resulting in cracked chips or broken solder joints. Before starting your production process,

test your cleaning equipment / process to insur eit does not degrade the capacitors.

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 the printed circuit board by the pressure of a test-probe, 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.

Install support pins as close to the test-probe as possible.

7.Printed Circuit Board Cropping

1. After mounting a capacitor on a printed circuit board, do not apply any stress to the capacitor that caused bending or twisting the board.

1-1. In cropping the board, the stress as shown may cause the capacitor to crack.

Cracked capacitors may cause deterioration of the insulation resistance, and result in a short.

Avoid this type of stress to a capacitor.

ꢀꢀ [In the case of Single-side Mounting]

An outline of the board separation jig is shown as follows.

Recommended example:

Stress on the component mounting position can be minimized by holding the portion close to the jig, and bend in the direction towards the side where the capacitors are mounted.

Not recommended example: The risk of cracks occurring in the capacitors increases due to large stress being applied to the component mounting position,

if the portion away from the jig is held and bent in thedirection opposite the side where the capacitors are mounted.

[In the case of Double-sided Mounting]

Since components are mounted on both sides of the board, the risk of cracks occurring can not be avoided with the above method.

Therefore, implement the following measures to prevent stress from being applied to the components.

(Measures)

(1) Consider introducing a router type separator.

ꢀIf it is difficult to introduce a router type separator, implement the following measures. (Refer to item 1. Mounting Position)

(2) Mount the components parallel to the board separation surface.

ꢀ

(3) When mounting components near the board separation point, add slits in the separation position near the component.

(4) Keep the mounting position of the components away from the board separation point.

GRM1885C2A331JA01-01A

ꢀ(2) Example of a Disc Separator

ꢀ An outline of a disc separator is shown as follows. As shown in the Principle of Operation, the top blade and bottom blade are aligned with the V-grooves on the printed circuit board to separate the board.

In the following case, board deflection stress will be applied and cause cracks in the capacitors.

(1) When the adjustment of the top and bottom blades are misaligned, such as deviating in the top-bottom, left-right or front-rear directions

(2) The angle of the V groove is too low, depth of the V groove is too shallow, or the V groove is misaligned top-bottom

IF V groove is too deep, it is possible to brake when you handle and carry it. Carefully design depth of the V groove with consideration about strength of material of the printed circuit board.

ꢀ(3) Example of Router Type Separator

ꢀThe router type separator performs cutting by a router rotating at a high speed.

ꢀSince the board does not bend in the cutting process, stress on the board can be suppressed during board separation.

ꢀ When attaching or removing boards to/from the router type separator, carefully handle the boards to prevent bending.

8. Assembly

1. Handling

ꢀ If a board mounted with capacitors is held with one hand, the board may bend.

ꢀ Firmly hold the edges of the board with both hands when handling.

ꢀIf a board mounted with capacitors is dropped, cracks may occur in the capacitors.

ꢀ Do not use dropped boards, as there is a possibility that the quality of the capacitors may be impaired.

2. Attachment of Other Components

ꢀ2-1. Mounting of Other Components

Pay attention to the following items, when mounting other components on the back side of the board after capacitors have been mounted on the opposite side.

When the bottom dead point of the suction nozzle is set too low, board deflection stress may be applied to the capacitors on the back side (bottom side), and cracks may occur in the capacitors.

· After the board is straightened, set the bottom dead point of the nozzle on the upper surface of the board.

· Periodically check and adjust the bottom dead point.

Suction Nozzle

ꢀ2-2. Inserting Components with Leads into Boards

When inserting components (transformers, IC, etc.) into boards, bending the board may cause cracks in the capacitors or cracks in the solder.

Pay attention to the following.

· Increase the size of the holes to insert the leads, to reduce the stress on the board during insertion.

· Fix the board with support pins or a dedicated jig before insertion.

· Support below the board so that the board does not bend. When using support pins on the board, periodically confirm that there is no difference in the height of each support pin.

Component with Leads

2-3. Attaching/Removing Sockets and/or Connectors

Insertion and removal of sockets and connectors, etc., might cause the board to bend.

Please insure that the board does not warp during insertion and removal of sockets and connectors, etc., or the bending may damage mounted components on the board.

Socket

2-4. Tightening Screws

The board may be bent, when tightening screws, etc. during the attachment of the board to a shield or chassis.

Pay attention to the following items before performing the work.

· Plan the work to prevent the board from bending.

· Use a torque screwdriver, to prevent over-tightening of the screws.

· The board may bend after mounting by reflow soldering, etc. Please note, as stress may be applied to the chips by forcibly flattening the board when tightening the screws.

Notice

■ Rating

1.Operating Temperature

1. The operating temperature limit depends on the capacitor.

1-1. Do not apply temperatures exceeding the maximum operating temperature.

It is necessary to select a capacitor with a suitable rated temperature that will cover the operating temperature range.

It is also necessary to consider the temperature distribution in equipment and the seasonal temperature variable factor.

1-2. Consider the self-heating factor of the capacitor

The surface temperature of the capacitor shall not exceed the maximum operating temperature including self-heating.

2.Atmosphere Surroundings (gaseous and liquid)

1. Restriction on the operating environment of capacitors.

1-1. Capacitors, 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.

GRM1885C2A331JA01-01A

■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 cracking caused by PCB expansion/contraction with heat, because stress on a chip is different depending on PCB material and structure.

When the thermal expansion coefficient greatly differs between the board used for mounting and the chip,it will cause cracking of the chip due to the thermal expansion and contraction.

When capacitors are mounted on a fluorine resin printed circuit board or on a single-layered glass epoxy board, it may also cause cracking of the chip for the same reason.

2.Item to be confirmed for Flow sordering

ꢀ If you want to temporarily attach the capacitor to the board using an adhesive agent before soldering the capacitor, first be sure that the conditions are appropriate for affixing the capacitor.

ꢀ If the dimensions of the land, the type of adhesive,the amount of coating, the contact surface area, the curing temperature, or other conditions are inappropriate, the characteristics of the capacitor may deteriorate.

1. Selection of Adhesive

1-1. Depending on the type of adhesive, there may be a decrease in insulation resistance. In addition, there is a chance that the capacitor might crack from contractile stress due to the difference

in the contraction rate of the capacitor and the adhesive.

1-2. If there is not enough adhesive, the contact surface area is too small, or the curing temperature or curing time are inadequate, the adhesive strength will be insufficient and the capacitor may loosen

or become disconnected during transportation or soldering.

If there is too much adhesive, for example if it overflows onto the land, the result could be soldering defects, loss of electrical connection, insufficient curing, or slippage after the capacitor is mounted.

Furthermore, if the curing temperature is too high or the curing time is too long, not only will the adhesive strength be reduced, but solderability may also suffer due to the effects of oxidation on

the terminations (outer electrodes) of the capacitor and the land surface on the board.

(1) Selection of Adhesive

ꢀEpoxy resins are a typical class of adhesive. To select the proper adhesive, consider the following points.

ꢀ1) There must be enough adhesive strength to prevent the component from loosening or slipping during the mounting process.

ꢀ2) The adhesive strength must not decrease when exposed to moisture during soldering.

ꢀ

3) The adhesive must have good coatability and shape retention properties.

ꢀ 4) The adhesive must have a long pot life.

ꢀ5) The curing time must be short.

ꢀ 6) The adhesive must not be corrosive to the exterior of the capacitor or the board.

ꢀ 7) The adhesive must have good insulation properties.

ꢀ

8) The adhesive must not emit toxic gases or otherwise be harmful to health.

ꢀ 9) The adhesive must be free of halogenated compounds.

(2) Use the following illustration as a guide to the amount of adhesive to apply.

2.Flux

2-1. 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 solderring.)

2-2. Flux containing too high a percentage of halide may cause corrosion of the terminations unless there is sufficient cleaning. Use flux with a halide content of 0.1% max.

2-3. Strong acidic flux can corrode the capacitor and degrade its performance.

Please check the quality of capacitor after mounting.

3.Leaching of the terminations

［As a Single Chip］

Set temperature and time to ensure that leaching of the

terminations does not exceed 25% of the chip end

3.Reflow soldering

The flux in the solder paste contains halogen-based substances and organic acids as activators.

Strong acidic flux can corrode the capacitor and degrade its performance. Please check the quality of capacitor after mounting.

4.Washing

1. Please evaluate the capacitor using actual cleaning equipment and conditions to confirm the quality, and select the solvent for cleaning.

2. Unsuitable cleaning may leave residual flux or other foreign substances, causing deterioration of electrical characteristics and the reliability of the capacitors.

5.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 low curing contraction.

The difference in the thermal expansion coefficient between a coating resin or a molding resin and the 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 the 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.

3. The halogen system substance and organic acid are included in coating material, and a chip corrodes by the kind of Coating material. Do not use strong acid type.

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, or 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 the sharp edge of an air driver, a soldering iron, tweezers, a chassis, etc. impacts strongly on the surface of the capacitor, the capacitor may crack and short-circuit.

1-3. Do not use a capacitor to which excessive shock was applied by dropping etc.

A capacitor dropped accidentally during processing may be damaged.

2.Characteristics Evaluation in the Actual System

1. Evaluate the capacitor in the actual system, to confirm that there is no problem with the performance and specification values in a finished product before using.

2. Since a voltage dependency and temperature dependency exists in the capacitance of high dielectric type ceramic capacitors, the capacitance may change depending

on the operating conditions in the actual system.

Therefore,be sure to evaluate the various characteristics, such as the leakage current and noise absorptivity, which will affect the capacitance value of the capacitor.

3. In addition,voltages exceeding the predetermined surge may be applied to the capacitor by the inductance in the actual system.

Evaluate the surge resistance in the actual system as required.
