11.3 Soldering conditions (reflow)  
• Pre-heating should be in such a way that the temperature difference between solder and product surface is limited to  
100°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 resulting in the deterioration of  
product quality.

11.4 Reworking with soldering iron  
The following requirements must be met to rework a soldered product using a soldering iron.  
Item  
Requirement  
150°C/approx. 1 min  
380°C max.  
Pre-heating  
Tip temperature of soldering iron  
Power consumption of soldering iron  
Tip diameter of soldering iron  
Soldering time  
80 W max.  
ø3 mm max.  
3 s (+1 s, -0 s)  
2 times max.  
Number of reworking operations  
* Avoid a direct contact of the tip of the soldering iron with the product. Such a  
direction contact may cause cracks in the ceramic body due to thermal shock.  
11.5 Solder volume  
Solder shall be used not to increase the volume too much.  
An increased solder volume increases mechanical stress on the product. Exceeding solder volume may cause the failure of  
mechanical or electrical performance.
