STIRRI® ASM-TF™ is a high-performance, no-clean tacky soldering flux engineered for both leaded and lead-free solder applications. This versatile flux is ideal for a broad range of soldering processes, including manual hand-soldering and automated assembly lines utilizing pneumatic dispensers, solder paste printers, and reflow ovens.

Featuring an RMA-grade performance, ASM-TF™ boasts an optimal viscosity and a light, creamy flux body leaving a clear, benign residue that can be reliably left on the board, eliminating the need for post-soldering cleaning in many applications. For situations requiring residue removal, it is easily cleaned with common solvents such as isopropanol (IPA), acetone, or industrial no-clean solvents. Optimal cleaning results are achieved when the Printed Circuit Board (PCB) is still warm. Cleaning is recommended for cosmetic reasons and to avoid voltage leakage on circuits with high impedance.

Classified as ROL0, this flux provides a truly no-clean residue and an odorless formulation, enhancing workplace safety and comfort. It incorporates QC-Aid™ technology, enabling instant visual Quality Control (QC) certification through UV light inspection.

STIRRI® ASM-TF™ exhibits low electrochemical migration and excellent surface insulation resistance, ensuring long-term reliability of soldered joints. Its superior performance makes it an outstanding choice for repair and rework operations, consistently delivering exceptional results across most surface finishes and with all popular soldering methods and techniques.
