Soldering And Handling Precautions:

The recommended method for soldering large SMC capacitor is reflow soldering. Wave soldering and manual soldering with Iron is not recommended.

Ceramic capacitors must be preheated with less than 2°C/sec rate to about 50°C below the reflow temperature. Sudden increase, or decrease in temperature more than the recommended rate, during soldering, may cause internal thermal cracks.
