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

Also cooling into the solvent after soldering should be in such a way that the temperature difference is limited to 100° C max.

Pre-heating should be in such a way that the temperature difference between solder and ferrite surface is limited to 150° C max.

Products should be soldered within the following allowable range indicated by the slanted line. The excessive soldering conditions
