11.2 Flux, Solder
・Use rosin-based flux.
・Don’t use highly acidic flux with halide content exceeding 0.2(wt)% (chlorine conversion value).
・ Don’t use water-soluble flux.
Flux
・Use Sn-3.0Ag-0.5Cu solder
・Standard thickness of solder paste : 200μm to 300μm
Solder
Other flux (except above) Please contact us for details, then use.
11.3 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.

Note : Do not directly touch the products with the tip of the soldering iron in order to prevent the crack
on the products due to the thermal shock.
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.

11.8 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.
