Stirri flux ASM-TF
Details
The Stirri ASM-TF is a universal no-clean ROL0 soldering flux. The ASM-TF provides a high-performance flux for professional repair specialists and engineers. The ASM flux features RMA-grade performance with a low viscosity and a light, creamy body, which leaves a clear 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 ASM features the proprietary QC-Aid UV tracer, making it easy to check for leftover residue. Cleaning off residue is easy with any generic IPA 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 ASM-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.
