## Long description

UNIPAK Unifix 3 100 g with Brush is a soldering paste designed for electronic assembly and repair tasks. Supplied in a 100 g container with an integrated brush applicator, the paste improves solder wetting and flow on component leads, pads and joints. The product is intended for manual soldering, rework and small board-level repairs where controlled flux application is required.
Advantages
The formulation promotes reliable solder flow and reduces the formation of solder bridges by improving wetting on metal surfaces. The integrated brush ensures controlled and precise application directly to component leads and pads, reducing excess flux use and mess. The 100 g size provides sufficient quantity for repeated repairs and routine assembly tasks without frequent replacement.
Suitable for
Manual soldering of through-hole and surface-mount components

Key specifications
Form: paste with brush applicator
Net weight: 100 g
Application: electronic soldering, rework and repairs
Compatibility: suitable for common solder alloys and typical PCB metals
Packaging: container with integrated brush for direct application
How to use
Prepare the work area with adequate ventilation and ensure the PCB and component leads are clean and free of oxidation or contaminants. Open the container and use the brush to apply a thin, even layer of paste to the solder pads or component leads. Heat with a soldering iron or hot air as appropriate for the component and solder alloy until the solder wets the joint and forms a solid connection. After soldering, remove any residue if required by cleaning procedures for the specific flux type used.
Usage recommendations
Use in a well-ventilated area and follow standard safety precautions for soldering and flux handling. Avoid excessive paste application to prevent bridging; apply sparingly and reapply only as necessary. Store the container sealed in a cool, dry place to maintain paste consistency and shelf life.
