High-temperature solder paste TECMAXX SMAR tube 50 g

TECMAXX SMAR tube 50 g is a high-temperature solder paste formulated for precision repair and assembly of electronic and mechanical components that must withstand elevated operating temperatures. Supplied in a compact 50 g syringe-like tube, this solder paste is designed for controlled application on small pads, connectors and joints where a higher melting point is required. The consistency of the paste and the tube format enable targeted dispensing for rework and localized soldering tasks without the need for larger cartridges or bulk containers.

Advantages

TECMAXX SMAR offers a stable high-temperature alloy composition that supports reliable joints in power electronics and heat-exposed connections. The 50 g tube format provides convenient, precise application and reduces material waste during small repair jobs. The paste is suitable for soldering components where conventional low-temperature solders would soften or fail under load, increasing service life and mechanical integrity of the repaired assembly.

Suitable for

• Rework and repair of power electronics and heat-generating modules
• Soldering of connectors, terminals and high-temperature joints
• Localised touch-up and precision assembly in electronic and mechanical systems
• Applications where a higher melting point than standard solders is required

Key specifications

• Net weight: 50 g tube
• High-temperature solder paste formulation suitable for elevated melting point applications
• Paste consistency compatible with syringe/tube dispensing for precision work
• Intended for manual application and small-scale repair tasks

How to use

Prepare the work area by cleaning surfaces to remove oxidation, grease and contaminants to ensure proper wetting. Cut the tube tip to the required aperture size and apply the solder paste sparingly to the target pad or joint. Position components and heat with an appropriate heat source, such as a hot air station or soldering iron with controlled temperature, to achieve the alloy's melting point and form a reliable joint. Allow the soldered area to cool naturally before handling. Follow standard ESD and safety practices throughout the process.

Usage recommendations

Use an appropriate temperature profile for high-temperature solders to avoid thermal shock to components. For best results, test on a sample substrate to determine optimal tip size and heating parameters. Store the tube in a cool, dry place and follow manufacturer guidance for shelf life and disposal of residues.
