11. Precautions for Use

This product is for use only with reflow soldering. It is designed to be mounted by soldering. If you want to use other

mounting method, for example, using a conductive adhesive, please consult us beforehand.

Also, if repeatedly subjected to temperature cycles or other thermal stress, due to the difference in the coefficient of

thermal expansion with the mounting substrate, the solder (solder fillet part) in the mounting part may crack.

The occurrence of cracks due to thermal stress is affected by the size of the land where mounted, the solder volume, and

the heat dissipation of the mounting substrate. Carefully design it when a large change in ambient temperature is

assumed.

11.1 Land dimensions

The following diagram shows the recommended land dimensions for reflow soldering.

0.86

2.00

0.80

(in mm)

*1 Do not use gilded pattern. A copper wire may cause open by dissolution of metallization.

*2 Please be careful that using the different land pattern may give the excessive stress to the product and cause the

degradation of board flex or other reliabilities.

11.2 Flux and solder used

Flux

• Use a rosin-based flux.

• Do not use a highly acidic flux with a halide content exceeding 0.2(wt)% (chlorine conversion value).

• Do not use a water-soluble flux.

Solder

• Use Sn-3.0Ag-0.5Cu solder.

• Standard thickness of solder paste: 100 μm to 150 μm

If you want to use a flux other than the above, please consult our technical department.

11.3 Soldering conditions (reflow)

• Pre-heating should be in such a way that the temperature difference between solder and product surface is limited to

100°C max.

Cooling into solvent after soldering also should be in such a way that the temperature difference is limited to 100°C

max.

Insufficient pre-heating may cause cracks on the product, resulting in the deterioration of product quality.

• Standard soldering profile and the limit soldering profile is as follows.

The excessive limit soldering conditions may cause leaching of the electrode and/or resulting in the deterioration of

product quality.

Number of reworking operations

* Avoid a direct contact of the tip of the soldering iron with the product. Such a

direction contact may cause cracks in the ceramic body due to thermal shock.

11.5 Solder volume

Solder shall be used not to increase the volume too much.

An increased solder volume increases mechanical stress on the product. Exceeding solder volume may cause the failure

of mechanical or electrical performance.

11.6 Product's location

The following shall be considered when designing and laying out PCBs.

(1) PCB shall be designed so that products are not subject to mechanical stress due to warping the board.

[Products direction]

Products shall be located in the sideways direction (length: a < b) to the mechanical stress.

Poor example

〈

〉

Good example

〈

〉

(2) Components location on PCB separation

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

Stress level

A > D^*1

A > B

(1) Turn the mounting direction of the component parallel to the

board separation surface.

(2) Add slits in the board separation part.

(3) Keep the mounting position of the component away from the

board separation surface.

A > C

*1 A > D is valid when stress is added vertically to the perforation as with hand separation.

If a cutting disc is used, stress will be diagonal to the PCB, therefore A > D is invalid.

(3) Mounting components near screw holes

When a component is mounted near a screw hole, it may be affected by the board deflection that occurs during the

tightening of the screw.

Mount the component in a position as far away from the screw holes as possible.

P8/9

11.7 Handling of substrate

After mounting products on a substrate, do not apply any stress to the product caused by bending or twisting to the

substrate when cropping the substrate, inserting and removing a connector from the substrate or tightening screw to the

substrate.

Excessive mechanical stress may cause cracking in the product.

Bending

Twisting

11.8 Cleaning

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

this product.

11.9 Storage and transportation

Storage period

Use the product within 12 months after delivery.

If you do not use the product for more than 12 months, check solderability before using it.

Storage conditions • The products shall be stored in a room not subject to rapid changes in temperature and humidity.

The recommended temperature range is -10°C to +40°C. The recommended relative humidity

range is 15% to 85%.

Keeping the product in corrosive gases, such as sulfur, chlorine gas or acid may cause the poor

solderability.

• Do not place the products directly on the floor; they should be placed on a palette so that they

are not affected by humidity or dust.

• Avoid keeping the products in a place exposed to direct sunlight, heat or vibration.

• Do not keep products in bulk packaging. Bulk storage could result in collisions between the

products or between the products and other parts, resulting in chipping or wire breakage.

• Avoid storing the product by itself bare (i.e. exposed directly to air).

Transportation

Excessive vibration and impact reduces the reliability of the products. Exercise caution when

handling the products.

11.10 Resin coating (including moisture-proof coating)

When the product is coated/molded with resin, its electrical characteristics may change.

A wire breakage issue may occur by mechanical stress caused by the resin, amount/cured shape of resin, or operating

condition etc.

Some resins contain impurities or hydrolyzable chlorine, which could result in corrosion of the conducting materials,

leading to wire breakage.

So, please pay your careful attention when you select resin in case of coating/molding the products with the resin.

Prior to use the coating resin, please make sure no reliability issue is observed by evaluating products mounted on your

board.

11.11 Mounting conditions

Check the mounting condition before using.

If installation conditions (nozzle, device requirements, etc.) are not suitable for the product, a pick-up error or shifting of

the pick-up position could occur, resulting in damage to the product.

In some cases, the laser recognition function of the mounting equipment may not recognize this product correctly.

Please contact us when using laser recognition. (There is no problem with the permeation and reflection type.)

11.12 Operating environment

Do not use this product under the following environmental conditions as it may cause deterioration of product quality.

(1) In the corrodible atmosphere such as acidic gases, alkaline gases, chlorine, sulfur gases, organic gases and etc.

(the sea breeze, Cl2, H2S, NH3, SO2, NO2, etc)

(2) In the atmosphere where liquid such as organic solvent, may splash on the products.

(3) In the atmosphere where the temperature/humidity changes rapidly and it is easy to dew.

11.13 Mounting density

If this product is placed near heat-generating products, be sure to implement sufficient heat-dissipating measures.

If this product is subjected to a significant amount of heat from other products, this could adversely affect product quality,

resulting in a circuit malfunction or failure of the mounted section. Also, be sure that the product is used in a manner so

that the heat that the product is subjected to from other products does not exceed the upper limit of the rated operating

temperature for the product.

11.14 Handling of product

・Sharp material such as a pair of tweezers or other material such as bristles of cleaning brush , shall not be touched

to the winding portion and electrode to prevent the breaking of wire.

・Mechanical shock should not be applied to the products mounted on the board to prevent the breaking of the core.
