Key Points When Soldering Polypropylene Capacitors

2025-02-16

Polypropylene capacitors require a very delicate process to avoid thermal damage when soldering. Here are some key points you should notice when you solder the board.

Key Points When Soldering Polypropylene Capacitors

For Automated Systems

 

Pre-Heat

Ensure that the board surface temperature stays below 110°C. Pre-heat exposure should be limited to 1 minute.

 

Wave Soldering

Max temperature is 260°C with a maximum exposure time of 4 seconds.

 

Post-Soldering

Allow sufficient time for the capacitor surface temperature to drop to ambient (25°C) if a secondary soldering process is needed.

For Hand Soldering

 

Iron/Tip Selection

Use an appropriately sized tip—large enough for the job but not too large to avoid damaging the capacitor.

 

Heat Sinks

Use heat sinks to protect the capacitor’s body during hand soldering.

 

Other Soldering Considerations

 

Adhesive Curing

Ensure the adhesive temperature does not exceed the safe operating temperature of the capacitor.

 

Physical Contact

Avoid direct contact between the capacitor and other components or the PCB during soldering.

 

Molten Solder

Solder should not come into contact with the capacitor body.

 

Cleaning

If using aqueous cleaning, ensure the capacitor has a “Mod A” moisture-resistant construction and adequate cooling time after wave soldering.
