The Stirri V5-TF is a no-clean ROL0 soldering flux without the glow UV tracers. Designed for universal applications by hot air at all temperatures, the V5-TF provides a high-performance, REACH-compliant flux for professional repair specialists and engineers. The V5-TF flux features optimal viscosity and leaves easily-removable residue. The flux is compatible with hot air rework stations and is made to be used with solder paste. Flux ensures good adhesion to most PCB finishes by negating the effect of solder oxidation, which helps achieve reliable solder joints. Cleaning off residue is easy with ultrasonic devices and can be done with most solvents. The V5-TF flux is halogen free, and is also formulated to produce less smoke during soldering, slightly reducing exposure to harmful fumes.
This soldering flux is the original Stirri product made in the USA. Stirri is the new name for the products which use the original Amtech recipe.
All versions share the same V5-TF flux chemistry and performance; only the fill volume and syringe body colour differ. Use the size and colour selector on this page to choose the variant that best fits your workflow.
