What is a common application for water-soluble flux?

Water-soluble flux is specifically formulated to be easily removed with water after the soldering process. This characteristic allows for thorough cleaning of solder joints, making it particularly valuable in applications where residual flux can lead to corrosion or interfere with electrical connections. The ability to wash off the flux simplifies maintenance and ensures that the workpieces maintain their integrity and usability over time.

In contrast, high-temperature applications may require non-water-soluble flux to withstand extreme conditions, while general electronic soldering can employ various types of flux depending on specific requirements. Applications requiring no cleaning would not benefit from water-soluble flux since they would not need the ease of washability provided by it.
