12. 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.  
12.1 Flux and Solder  
Flux  
Use rosin-based flux, (with converting chlorine content 0.06 to 0.1(wt)%. ),  
but not highly acidic flux  
(with Halogen content exceeding 0.2(wt)% conversion to chlorine).  
Do not use water-soluble flux.  
Solder  
Use Sn-3.0Ag-0.5Cu solder  
12.2 Assembling  
<Exclusive use of Reflow soldering>  
Flow soldering may cause deterioration in insulation resistance.  
So, reflow soldering shall be applied for this product.  
12.3 Cleaning Conditions  
Do not clean after soldering. Some cleaning agents may degrade bonding strength,and characteristics of  
products by detaching. If cleaning,please contact us.  
12.4 Resin coating  
The electrical performance may change due to high cure-stress of resin to be used for coating/molding  
products. An open circuit issue may occur by mechanical stress caused by the resin, amount/cured shape of  
resin, or operating condition etc. Some resin contains some impurities or chloride possible to generate  
chlorine by hydrolysis under some operating condition may cause corrosion of wire of coil, leading to open  
circuit. So, please pay your careful attention when you select resin in case of coating/molding the products  
with the resin. Prior to use the coating resin, please make sure no reliability issue is observed by evaluating  
products mounted on your board.  
12.5 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 due to  
warping the board.  
Products direction]  
Products shall be location the sideways

Stress.  
Poor example  
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  
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.

(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.

Products shall not be arranged on the line of a series of holes when  
there are big holes in P.C.B. (Because the stress concentrate on the  
line of holes.)

No pattern  
(in mm)  
1 If the pattern is made with wider than 1.2mm. It will result to let component turn around,  
because melting speed is different. In the worst case, short circuit between lines may be occured.  
2 If the pattern is made with less than 0.4mm , in the worst case , short circuit between lines may be  
occurred deu to the spread of soldering paste or mount placeing accuracy.  
3 If the pattern is made with wider than 0.8mm, the strength of bending will be reduced.  
4 Do not use gilded pattern. A copper wire may cause open by dissolution of metallization.  
12.8 Standard Soldering Condition  
1. Reflow Soldering  
(1) Standard printing pattern for soldering.  
Standard thickness of the solder paste should be 100 to 150µm.  
Use the solder paste printing pattern of the right pattern.  
For the resist and copper foil pattern, use standard land dimensions.  
Use the Solder Sn-3.0Ag-0.5Cu for pattern printing.

(2) Soldering Temperature  
P8/9  
Temperature difference between soldering and surface of components must be within 150°C, in preheating.  
When components are immersed in liquid after soldering, temperature difference should be within 100°C. If  
preheating is not enough, components may be cracked and cause deterioration in insulation resistance.  
(3) Soldering Condition  
Standard soldering profile and the limit soldering profile is as follows.
