9-2. Soldering Conditions
Products can be applied to reflow and flow soldering.
(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.
Solder
Use Sn-3.0Ag-0.5Cu solder
Standard thickness of solder paste : 100 µm to 200 μm
(2) Soldering conditions
• 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.

(T:Chip thickness)
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.
9-5. 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 are not subject to the mechanical stress for board warpage.

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.
