Frequently Asked Questions
What does "8.9HF" mean in Indium 8.9HF?
8.9HF refers to Indium Corporation's flux designation: 8.9 is the flux series (no-clean, low-residue) and HF stands for Halogen-Free. This means the paste contains less than 900ppm of chlorine and bromine, meeting IPC J-STD-004 halogen-free requirements.
What applications is Indium 8.9HF best suited for?
It is optimized for fine-pitch SMT components (0201, 0402, 0603), BGA and CSP packages, and high-reliability assemblies in automotive, medical, and aerospace electronics. The Type 4 powder size ensures clean aperture release on stencils down to 0.4mm pitch.
Does Indium 8.9HF require post-reflow cleaning?
No. As a no-clean formulation, the flux residue left after reflow is minimal, non-corrosive, and electrically safe — no cleaning step is required for most applications. If your process requires cleaning, Indium's water-wash paste lines (3.2 or 3.2HF) are the appropriate alternative.
What is the shelf life and storage requirement for this solder paste?
Indium 8.9HF has a 6-month shelf life when stored refrigerated at 2–10°C (35–50°F). Allow the cartridge to reach room temperature (approximately 4 hours) before use. Do not use paste that has exceeded its shelf life or shows signs of separation.
