Other flux (except above) Please contact us for details, then use.
11.3 Flow soldering conditions / Reflow soldering conditions
・Pre-heating should be in such a way that the temperature difference between solder and product surface is limited to
150°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.

(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.
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.
Frequency : 28kHz to 40kHz
Time : 5 minutes max.
(3) Cleaner
1. Alternative cleaner
・Isopropyl alcohol (IPA)
2. Aqueous agent
・PINE ALPHA ST-100S
(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.

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.
