10-2. Mounting
Conditions
・
Please check the mounting condition before using.
・
Using mounting conditions (nozzles, equipment conditions, etc.) that are not suitable for products
may lead to pick up errors, misalignment, or damage to the product.
10-3.Soldering Conditions
(1) Flux,Solder
Flux
Use rosin-based flux, but not highly acidic flux (with chlorine content exceeding 0.2(wt)%. )
Do not use water-soluble flux.

•
Pre-heating should be in such a way that the temperature difference between solder and ferrite surface is limited
to 150
℃
max. Also cooling into solvent after soldering should be in such a way that the temperature difference
is limited to 100
℃
max.
Insufficient pre-heating may cause cracks on the ferrite, 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.

Accordingly increasing the solder volume, the mechanical stress to product is also increased.
Exceeding solder volume may cause the failure of mechanical or electrical performance.
10-5.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 for board warpage.

(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.
(2) Add slits in the board separation part.
(3) Keep the mounting position of the component away from the board separation surface.

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.

Screw Hole
10-6.Mounting density
Add special attention to radiating heat of products when mounting the inductor near the products with heating.
The excessive heat by other products may cause deterioration at joint of this product with substrate.
10-7.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, avoiding the resonance phenomenon
at the mounted products and P.C.B.
Power:20W/

to 40kHz
Time:5 min 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.

10-9. Resin coating
When products are coated with resin, please contact us in advance.
10-10. 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.

10-11.Storage Conditions
(1)Storage period
Use the products within 6 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.
