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.

11.5 Solder Volume

Solder shall be used not to be exceeded the upper limits as shown below.

・

Accordingly increasing the solder volume, the mechanical stress to Chip is also increased.

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 P.C.B.’s.

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

［Products direction］

Electrode

Products shall be located in the sideways

direction to the mechanical stress.

(Good example)

（Poor example）

Electrode

(2) Components location on P.C.B. 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

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

the board separation surface.

D 1

(2) Add slits in the board separation part.

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

the board separation surface.

Seam

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.

Electrode

Slit

(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.

Recommended

Screw Hole

11.7 Cleaning Conditions

Products shall be cleaned on the following conditions.

(1) Cleaning temperature shall be limited to 60°C max.(40°C max for IPA.)

(2) Ultrasonic cleaning shall comply with the following conditions with avoiding the resonance phenomenon

at the mounted products and P.C.B.

Power : 20 W / l max.

(3) Cleaner

Alcohol-based cleaner: IPA

Aqueous agent: PINE ALPHA ST-100S

Frequency : 28kHz to 40kHz

Time : 5 minutes max.

(4) There shall be no residual flux and residual cleaner after cleaning.

In the case of using aqueous agent, products shall be dried completely after rinse with de-ionized water in

order to remove the cleaner.

(5) Other cleaning

Please contact us.

11.8 Resin coating

The inductance value may change due to high cure-stress of resin to be used for coating/molding products. An open

circuit issue may occur by mechanical stress caused by the resin, amount/cured shape of resin, or operating condition

etc. Some resin contains some impurities or chloride possible to generate chlorine by hydrolysis under some operating

condition may cause corrosion of wire of coil, leading to open circuit. 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.

11.9 Caution for use

・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 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

11.10 Handling of a 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

11.11 Storage and Handling Requirements

(1) Storage period

Use the products within 12 months after delivered.

Solderability should be checked if this period is exceeded.

(2) Storage conditions

・Products should be stored in the warehouse on the following conditions.

Temperature : -10 ~ 40°C

Humidity

: 15 to 85% relative humidity No rapid change on temperature and humidity

The electrode of the products is coated with solder. Don't keep products in corrosive gases such as

sulfur,chlorine gas or acid, or it may cause oxidization of electrode, resulting in poor solderability.

・Products should not be stored on bulk packaging condition to prevent the chipping of the core and the breaking

of winding wire caused by the collision between the products.

・Products should be stored on the palette for the prevention of the influence from humidity, dust and so on.

・Products should be stored in the warehouse without heat shock, vibration, direct sunlight and so on.

(3) Handling Condition

Care should be taken when transporting or handling product to avoid excessive vibration or mechanical shock.

12.
