## Summary description

Bisan LB3 is a 250 g tin of fluxed soldering paste designed for soft soldering tasks. The paste combines solder powder with active flux to improve wetting and joint formation during manual soldering, rework, and component assembly. Supplied in a sealed metal can, it is intended for electronics repair, small-batch PCB work and precision soldering where controlled application is required.

## Long description

Bisan LB3 250 g is a fluxed soft solder paste supplied in a sealed metal tin for manual soldering and rework tasks. The product combines fine solder powder with an active flux vehicle to promote reliable wetting and consistent joint formation on electronic components and PCB pads. Packaged to reduce contamination and moisture ingress, this solder paste is intended for electronics repair, small-batch assembly and precision soldering operations that require controlled paste application and predictable solder flow.
Advantages
The fluxed formulation improves solder wetting and reduces the need for additional flux during manual operations. The paste consistency allows accurate placement and reduced bridging on fine-pitch joints. Supplied in a 250 g tin, the material is convenient for repeated use in workshop environments and provides stable handling properties for hand soldering and touch-up rework. The sealed metal can helps protect the paste from contamination and slows down drying, preserving performance between uses.
Suitable for
 Manual soldering and touch-up rework on printed circuit boards
 Component assembly and through-hole or surface-mount repairs
 Small-batch production and prototype PCB work
 Precision soldering where controlled paste application is required
Key specifications
 Form: fluxed solder paste (semi-solid)
 Net weight: 250 g (tin)
 Packaging: sealed metal can to limit contamination and moisture
 Intended use: soft soldering for electronics repair and rework
 Application method: manual dispensing, pick-and-place for small batches, soldering iron reflow
How to use
Before use, ensure the work area is clean and components and PCB pads are free of oxidation, oils or debris. Stir or knead the paste in the tin to obtain a uniform consistency, taking care to avoid introducing contaminants. Apply the required amount of paste to pads or component leads with a syringe, spatula or fine applicator. Heat the joint using a controlled soldering iron or local reflow method until the solder flows and forms a continuous fillet; allow cooling before moving the assembly. Follow standard safety practices for ventilation and personal protective equipment when soldering.
Usage recommendations
Store the tin in a cool, dry place and reseal after each use to reduce oxidation and drying. Use within the manufacturer’s recommended shelf life and consult material safety data sheets for handling and disposal instructions. For best results on fine-pitch components, practice amount and placement control and use a soldering tip with appropriate thermal capacity.
