Indium8.9HF Pb-free solder paste is halogen-free per the EN14582 test method. It is made with SAC305 and a Type 4 (88.5%) powder. Specifically designed to help Avoid the Void® , Indium8.9HF produces low-voiding results PLUS excellent stability. It also eliminates hot and cold slump, provides high oxidation resistance, and wets well to oxidized BGA and pad surfaces. Indium8.9HF also provides high transfer efficiency through small apertures and has excellent solder performance under high temperature and long reflow processes. This solder paste has a clear residue and is backward compatible with SnPb alloys.
