10-2.Soldering Conditions
(1) Flux,Solder
Flux
Solder
Use rosin-based flux, but not highly acidic flux (with chlorine content exceeding 0.2(wt)%. )
Do not use water-soluble flux.
Use Sn-3.0Ag-0.5Cu solder
Standard thickness of solder paste : 50
µm
to 80
m
(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.

Soldering
time : 3(+1,-0) seconds.
Soldering
iron output: 80W max.
Tip diameter:φ3mm max.
Times : 2times max.
Note :Do not directly touch the products with the tip of the soldering iron in order to prevent the crack
on the ferrite material due to the thermal shock.
10-4.Solder Volume
Solder shall be used not to be exceed as shown below.

(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.
