9.2 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 to 150μm.
9.3 Reflow soldering conditions
・Inductance value may be changed a little due to the amount of solder.
So, the chip coil shall be soldered by reflow so that the solder volume can be controlled.
・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.

9.5 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.

9.6 Mount Shock
Over Mechanical stress to products at mounting process causes crack and electrical failure etc.
9.7 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]
a
b
〈 Poor example 〉
Products shall be located in the sideways
direction (Length: a<b) to the mechanical
stress.
〈 Good example 〉
(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
(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.

9.8 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.
9.9 Resin coating
The inductance value may change and/or it may affect on the product's performance due to high cure-stress
of resin to be used for coating / molding products. So please pay your careful attention when you select resin.
In prior to use, please make the reliability evaluation with the product mounted in your application set.
9.10 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
9.11 Storage and Handing Requirements
(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.
Temperature : -10°C to 40°C
: 15% to 85% relative humidity No rapid change on temperature and humidity
Humidity
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 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.
・Products should be stored under the airtight packaged condition.
(3) Handling Condition
Care should be taken when transporting or handling product to avoid excessive vibration or mechanical shock.
