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 :60μm~100μm.
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.
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.

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.

T : thickness of product
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]

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.
MURATA MFG.CO., LTD

Spec No.JELF243C-9101D-01
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.

*1 A > D is valid when stress is added vertically to the perforation as with Hand Separation.
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 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
When products are coated with resin, please contact us in advance.
11.9 Handling of a substrate
(1)There is a possibility of chip cracking caused by PCB expansion/contraction with heat, because stress
on a chip is different depending on PCB material and structure.
When the thermal expansion coefficient greatly differs between the board used for mounting and the chip,
it will cause cracking of the chip due to the thermal expansion and contraction.
The chip is assumed to be mounted on the PCB of glass-epoxy material, and we don't test with other
PCB material which has different thermal expansion coefficient from Glass-epoxy.
When other PCB materials are considered, please be sure to evaluate by yourself.

(2)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.
In case of the mounting on flexible PCB, there is a possibility of chip cracking caused by mechanical stress
even from small bending or twisting.
When the flexible PCB is considered, please be sure to evaluate by yourself.
Bending
Twisting
Substrate restriction
・Don’t mount on FPC(Flexible printed circuits)
・When components are mounted on substrate of under 6-layers, please contact us in advance.
To mount components on FPC or substrate of under 6-layers may cause of cracking issue by stress.
11.10 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.
