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.
・Use Sn-3.0Ag-0.5Cu solder.
・Standard thickness of solder paste : 100μm~150μm.
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
products 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.

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 Attention regarding P.C.B. bending
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]
a

〈 Poor example〉
〈 Good example〉
Products shall be located in the sideways
direction (Length: a<b) to the mechanical
stress.
(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.

(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 capacitor in a position as far away from the screw holes as possible.
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 min max.
(3) Cleaner
1. Alcohol type 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
Inductance value may be changed due to the large cure-stress of the resin when products are coated
with resin. In this case, take care when you select resin to prevent the deterioration of the product quality.
11.9 Caution for use
The pattern of the chip coil is covered with the protection film. But the handing the chip coil shall be taken
care so that the chip coil would not be damaged with the pick-up nozzle, the sharp substance and so on.

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 Handing 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°C ~ 40°C
Humidity
: 15% to 85% relative humidity No rapid change on temperature and humidity.
・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.
