As a leading provider of high-reliability, AI-enabling soldering materials, three Indium Corporation experts will share new research and insights on addressing advanced packaging and high-power performance challenges at the IMAPS Symposium 2026, September 29-October 1, in Boston, Massachusetts.
September 30, 11:30-11:55 a.m. EDT – Novel Interconnect Materials for Advanced Packaging Assembly Processes, presented by Sze Pei Lim, Senior Global Product Manager, Semiconductor and Advanced Materials.
This presentation will cover innovative materials for advanced packaging and heterogeneous integration, including novel ultra-low residue flux formulations for flip-chip-attach that are compatible with underfill and molding compounds, an adhesive agent for fluxless soldering, and solder paste for ultra-fine-pitch printing. These novel materials are critical enablers for high-density packaging applications. Use cases for high-density SiP modules, TCB and LAB, for advanced packaging, and 2.5D modules will also be discussed.
September 30, 13:00-13:25 EDT – Material Solutions for AI/HPC Packaging from Wafer Bumping to System Assembly, presented by Jason Chou, Senior Area Technical Manager.
This session introduces specialized materials designed to address solder joint integrity, thermal management, and other vulnerabilities to enable better AI performance. Solutions presented include ultra-low residue flux materials for micro-bump wafer bumping and Chip-on-Wafer processes, mid-temperature solder pastes to eliminate Head-in-Pillow (HIP) and Non-Wet-Open (NWO) defects, and advanced thermal interface materials (TIMs) designed to significantly enhance the thermal efficiency of high-performance computer (HPC) chips.
September 30, 13:30-13:55 EDT – A Bi-free, In-containing, Lower-temperature Solder Applicable in Large BGA Assembly for HPC, presented by Hongwen Zhang, Ph.D., Research and Development Director and Principal Metallurgist.
This presentation introduces a Bi-free, indium-containing, lower-temperature solder paste designated “DFLT” that was developed to enable hierarchical assembly with enhanced mechanical and electrical reliability. It will highlight DFLT’s dual-powder formulation and successful use across step soldering, hot bar soldering, rework, and board-level assembly. With peak reflow temperature as low as 210°C, DFLT can help mitigate warpage-related defects in large BGA assemblies while delivering significant improvements in drop-shock resistance and electromigration performance compared with bismuth-tin-silver (BiSnAg) alloys and providing performance comparable to or exceeding SAC305.
