Frequently Asked Questions

Q: What materials is this liquid soldering flux compatible with?

A: This rosin core soldering flux is compatible with a wide range of materials including stainless steel, copper, iron, nickel, galvanized sheets, and battery pole pieces, making it highly versatile for electronics repair, metalwork, and battery electrode soldering.

Q: How much flux is included and what are the bottle dimensions?

A: Each bottle contains 30ml of liquid soldering flux and weighs approximately 40g. The bottle measures 2.8 × 11 cm (1.1 × 4.33 inches), making it compact and easy to handle for precise application.

Q: Is this flux suitable for both manual and automated soldering?

A: Yes! This liquid soldering flux supports both manual hand-soldering and automated soldering processes, making it an ideal choice for hobbyists, repair technicians, and industrial assembly operations alike.

Q: Does this flux leave residue after soldering?

A: The rosin core formula is designed for clean application with minimal splatter. Post-soldering residue can typically be cleaned with isopropyl alcohol. Always clean boards after soldering for best long-term conductivity results.
