11.3 Flow soldering conditions / 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 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 resultingin the

deterioration of product quality.
