## Summary description

Bisan LB3 soldering paste is a flux paste supplied in a 100 g tin, designed for soft (low-temperature) soldering.

Suitable for manual soldering tasks where a concentrated flux paste is required.

## Long description

Bisan LB3 soldering paste in a 100 g tin is a flux paste formulated for soft (low-temperature) soldering. It is intended to clean and activate metallic surfaces prior to soldering, improve wetting and solder flow, and help form reliable joints during manual soldering operations. The paste consistency makes it easy to apply to small joints, component leads and localized repair areas in electronics and metalwork.
Advantages
The flux paste provides targeted cleaning and activation of metal surfaces, reducing oxidation and facilitating capillary action of solder. Its paste form allows controlled application without excessive spreading, which is useful for delicate electronic assemblies and spot repairs. The product supports improved solder wetting and flow, leading to stronger, more consistent joints and fewer cold joints when used with appropriate solder and technique.
Suitable for
Soldering electronic components on printed circuit boards and through-hole joints
Manual soft-solder repairs of wiring, connectors and small metal parts
Spot soldering and rework where precise flux placement is required
Hobby electronics, model making and small metalwork repairs
Key specifications
Form: viscous paste in a screw-top tin designed for manual access
Weight: 100 g packaging suitable for workshop and hobby use
Application temperature: formulated for low-temperature (soft) soldering processes
Compatibility: suitable for common tin-lead and low-temperature lead-free solders used in manual soldering
Usage: concentrated flux for localized application and controlled wetting
How to use
Apply a small amount of the paste directly to the joint area using a wooden stick, plastic spatula or a brush to avoid contaminating the tin. Heat the joint with a soldering iron to the appropriate soldering temperature and feed solder to the heated joint; the flux will activate, clean the surfaces and promote solder flow. After soldering, remove any flux residues if required by your application or repair standards, using a suitable flux cleaner or isopropyl alcohol and a brush.
Usage recommendations
Use personal protective measures such as gloves and eye protection when handling flux paste. Work in a well-ventilated area to avoid inhaling fumes generated during soldering. Store the tin closed in a cool, dry place to prevent contamination and drying of the paste. Follow equipment manufacturer guidelines for soldering temperatures and cleaning procedures to achieve reliable joints.
