11.3 Flow soldering / Reflow soldering conditions

・Pre-heating should be in such a way that the temperature difference between solder and product surface is limited to

150°C max. Cooling into solvent after soldering also should be in such a way that the temperature difference is

limited to 100°C max.

Insufficient pre-heating may cause cracks on the product, resulting in the deterioration of products 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.
