10-2. Soldering Conditions

Products can be applied to reflow and flow soldering.

(1) Flux, Solder

Use rosin-based flux, but not highly acidic flux (with chlorine content exceeding 0.2(wt)%. )

Do not use water-soluble flux.

Flux

Use Sn-3.0Ag-0.5Cu solder

Standard thickness of solder paste : 100 µm to 200 μm

Solder

(2) Soldering conditions

• Pre-heating should be in such a way that the temperature difference between solder and ferrite surface is

limited to 150°C max. Also cooling into solvent after soldering should be in such a way that the temperature

difference is limited to 100°C 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.
