The Stirri V3-TF is a universal no-clean ROL0 soldering flux. The V3-TF provides a high-performance, REACH-compliant flux for professional repair specialists and engineers. The V3-TF flux features optimal viscosity and leaves a fully translucent residue. The flux is compatible with hot air rework stations and is designed to be used with solder paste. Flux ensures good adhesion to most PCB finishes by negating the effect of oxidation of solder, which helps achieve reliable solder joints. Additionally, the Stirri V3-TF features the proprietary QC-Aid UV tracer, making it easy to check for leftover residue. Cleaning off residue is easy with any generic IPA, vapour degreaser or ultrasonic devices and most solvents.
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.
The Stirri V3-TF is available in both clear and amber syringes and in 5g, 10g and 30g. Amber syringes protect the flux from UV radiation and thus ensure a longer flux lifespan than the clear syringes.
