ꢀꢀꢀ⑤Medical equipment ⑥Transportation equipment(vehicles,trains,ships,etc.) ⑦Traffic signal equipment

ꢀꢀꢀ⑧Disaster prevention / crime prevention equipment

⑨Data-processing equipment

ꢀꢀꢀ⑩Application of similar complexity and/or reliability requirements to the applications listed in the above.

■Storage and Operation condition

1. The performance of chip MLCC on Interposer (ZR□ series, 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.

2.Measurement of Capacitance

1. Measure capacitance with the voltage and frequency specified in the product specifications.

1-1. The output voltage of the measuring equipment may decrease occasionally when capacitance is high.

Please confirm whether a prescribed measured voltage is impressed to the capacitor.

1-2. The capacitance values of high dielectric constant type capacitors change depending on the AC voltage applied.

Please consider the AC voltage characteristics when selecting a capacitor to be used in a AC circuit.

3.Applied Voltage

1. Do not apply a voltage to the capacitor that exceeds the rated voltage as called out in the specifications.

1-1. Applied voltage between the terminals of a capacitor shall be less than or equal to the rated voltage.

(1) When AC voltage is superimposed on DC voltage, the zero-to-peak voltage shall not exceed the rated DC voltage.

When AC voltage or pulse voltage is applied, the peak-to-peak voltage shall not exceed the rated DC voltage.

(2) Abnormal voltages (surge voltage, static electricity, pulse voltage, etc.) shall not exceed the rated DC voltage.

(E：Maximum possible applied voltage.)

1-2. Influence of over voltage

Over voltage that is applied to the capacitor may result in an electrical short circuit caused by the breakdown

of the internal dielectric layers .

The time duration until breakdown depends on the applied voltage and the ambient temperature.

4.Type of Applied Voltage and Self-heating Temperature

1.Confirm the operating conditions to make sure that no large current is flowing into the capacitor due to the

continuous application of an AC voltage or pulse voltage.

When a DC rated voltage product is used in an AC voltage circuit or a pulse voltage circuit, the AC current

or pulse current will flow into the capacitor; therefore check the self-heating condition.

Please confirm the surface temperature of the capacitor so that the temperature remains within the upper limits

of the operating temperature, including the rise in temperature due to self-heating. When the capacitor is

used with a high-frequency voltage or pulse voltage, heat may be generated by dielectric loss.

[Example of Temperature Rise (Heat Generation) in Chip

by the applied voltage is within the allowed range .

(2) In the DC voltage characteristics, the rate of

capacitance change becomes larger as voltage

increases, even if the applied voltage is below

the rated voltage. When a high dielectric constant

type capacitor is used in a circuit that requires a

■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.

because ZR□ series are easier to shift the mounting position than standard MLCC.

2. To check the overturn and reverse of ZR□ series.

3. To control mounting speed carefully, because ZR□ series is heavier than standard MLCC.

4. 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.

4-1. 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.

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.

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.

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.

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

4-2.Flow Soldering

1. ZR□ series is not apply flow soldering.

4-3.Correction of Soldered Portion

Do not correct with a soldering iron for ZR□ series.

Correction with a soldering iron for ZR□ series may cause loss suppress acoustic noise,

because the solder amount become excessive.

Caution

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 insure

it 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.

1-2. Avoid vibration of the board by shock when a test -probe 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

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.

[Bending]

[Twisting]

2. Check 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 (Disc separator, router

Caution

(1) Example of a suitable jig

[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 the

direction 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.

(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.

Caution

(3) Example of Router Type Separator

[ Outline Drawing ]

Router

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.

Notice

■Soldering and Mounting

1.PCB Design

1. Notice for Pattern Forms

1-1. 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.
