Indium6.6HF is a versatile, water-soluble solder paste flux, formulated for air or nitrogen reflow. It is made with Sn63/Pb37 and a Type 4 (89.5%) powder. It is capable of SnPb and Pb-free assembly processes with an exceptional reflow process window. This solder paste provides exceptional stencil printing performance, with long stencil life and excellent response-to-pause.
Indium6.6HF exhibits superior wetting to a variety of surface finishes and exhibits the best voiding performance, with fewest voids, reduced size of largest voids, and overall minimized voiding for BGAs, CSPs, and BTCs (QFNs, DPAKs, LGAs, etc.). It maintains tack over time and can be cleaned easily.
