12. ! Caution
12.1. Limitation of Applications
Please contact us before using our products for the applications listed below which require especially high reliability for
the prevention of defects which might directly cause damage to the third party’s life, body or property.
(1) Aircraft equipment
(2) Aerospace equipment (3) Undersea equipment (4) Power plant control equipment
(5) Medical equipment (6) Transportation equipment(automobiles, trains, ships, etc.) (7) Traffic signal equipment
(8) Disaster prevention / crime prevention equipment (9) Data-processing equipment
(10) Applications of similar complexity or with reliability requirements comparable to the applications listed in the above
12.2. Corrosive gas
Please refrain from use since contact with environments with corrosive gases (sulfur gas [hydrogen sulfide, sulfur
dioxide, etc.], chlorine, ammonia, etc.) or oils (cutting oil, silicone oil, etc.) that have come into contact with the
previously stated corrosive gas environment will result in deterioration of product quality or an open from deterioration
due to corrosion of product electrode, etc. We will not bear any responsibility for use under these environments.
13. Notice
Products can only be soldered with reflow.
This product is designed for solder mounting.
Please consult us in advance for applying other mounting method such as conductive adhesive.
13.1. Mounting direction of a product
In the case of mounting, Polarity Marking should surely serve as the upper surface.
When mounted upside down, since the Polarity Marking is formed with the conductor, it has a possibility that the shortcircuit between terminals may occur.
13.2.Flux and Solder
Flux
Use rosin-based flux, Do not use highly acidic flux (with chlorine content exceeding 0.2(wt)%).
Do not use water soluble flux.
Solder
Use Sn-3.0Ag-0.5Cu solder
Other flux (except above) Please contact us for details, then use.
13.3.Note for Assembling
< Thermal Shock >
Pre-heating should be in such a way that the temperature difference between solder and products surface is limited
to 100°C max. Also cooling into solvent after soldering should be in such a way that the temperature difference is
limited to 100°C max.
13.4.Attention Regarding P.C.B. Bending
The following shall be considered when designing P.C.B.'s and laying out products.
(1) P.C.B. shall be designed so that products are not subject to the mechanical stress for board warpage.
[Products direction]
a
b
〈 Poor example 〉
Products shall be located in the sideways
direction (Length:ab) 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.

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 component in a position as far away from the screw holes as possible.
13.5. Pre-heating Temperature
Soldering shall be handled so that the difference between pre-heating temperature and solder temperature shall be
limited to 100°C max. to avoid the heat stress for the products.
13.6. Reflow Soldering
1) Soldering paste printing for reflow
· Standard thickness of solder paste: 100µm to 150µm.
· Use the solder paste printing pattern of the below pattern.
· For the resist and copper foil pattern, use standard land dimensions.
