SUPERCAPACITOR SOLDERING GUIDELINES
Hand Soldering (soldering iron)
Warning. Do not touch the supercapacitor external sleeve with the soldering rod which can cause the sleeve to melt or crack.
1. When soldering supercapacitors with a soldering iron the exposure should be limited to 350°C for 3.5 seconds.
2. Circuit board thickness should be 1.6mm +/-0.5mm
3. At no time should the soldering iron come in contact with the capacitor body. Contact with the body can cause the sleeving to crack or melt.
4. To remove a capacitor from a printed circuit board, the capacitor should be pulled on gently after the solder holding the capacitor to the circuit board has sufficiently melted.
1. Supercapacitors are not to be immersed into the solder bath at any time. To do so would result in the internal pressure within the capacitor to rise, damaging the capacitor.
2. Supercapacitors are only to be mounted to the topside of the circuit board.
3. Circuit board thickness should be 1.6mm +/-0.5mm.
4. Recommended preheating – Preheat board from the bottom side only, bring the top of the board to 100C maximum immediately before soldering. Use a maximum preheating time of 60 seconds for a PCB 0.8mm or thicker. Following the table below for wave soldering of leads only:
|Solder Bath Temperature (°C)||Recommended Solder Exposure (Seconds)||Maximum Exposure (Seconds)|
5. Heat conducting components like resistors and lead wires, should not be in contact or near supercapacitors. This will prevent heat from these components from being transmitted to the capacitor's sleeve and damaging the sleeve.
Reflow soldering should not be used on any Cornell Dubilier supercapacitors.
