Indium Corporation will present a selection of its advanced solder paste portfolio at EFX 2026, taking place 6–8 October in Stuttgart, Germany (booth #9A79). The event, focused on the European electronics manufacturing sector, provides the company with a platform to address current process challenges in automotive electronics, low-temperature assembly and fine-feature printing — three segments where solder material selection has a direct impact on yield and long-term reliability.
The Durafuse HR alloy technology is positioned for high-reliability automotive applications requiring robust thermal cycling performance across the −40 °C/+125 °C and −40 °C/+150 °C ranges. According to Indium Corporation, the paste delivers improved resistance to solder joint cracking and increased shear strength compared with standard SAC alloys, alongside enhanced voiding control — characteristics that are increasingly demanded as automotive electronics migrate toward more thermally stressed environments such as powertrain and ADAS modules.
Durafuse LT addresses the growing interest in low-temperature soldering as a strategy to reduce energy consumption during reflow and to accommodate temperature-sensitive substrates. Indium Corporation states that the alloy system outperforms conventional bismuth-based alternatives such as BiSn and BiSnAg in thermal cycling and drop shock, and can match or exceed SAC305 performance under optimised process conditions. This positions Durafuse LT for step-soldering applications and assemblies incorporating large BGAs with complex warpage profiles — a recurring challenge in consumer, industrial and automotive PCB assembly.
The third product highlighted is Indium12.9HF, described as a no-clean, halogen-free solder paste formulated specifically for fine-feature printing. The paste targets component sizes down to 01005 and 008004, where stencil print transfer efficiency and paste release consistency are critical. The company claims the formulation achieves high SPI yields across a broad process window, with low voiding at BGA, CSP, LGA and QFN land patterns and high oxidation resistance in air reflow on pad geometries as small as 175 microns — without graping or solder balling defects.
The focus on fine-feature printing reflects a wider industry trend: as component miniaturisation continues and area-array packages become more prevalent in high-density assemblies, solder paste rheology and stencil compatibility become key differentiators. European EMS providers and OEMs adopting 008004 components in production will be evaluating pastes that can deliver consistent aperture release at reduced stencil thicknesses without compromising joint integrity.
Indium Corporation, headquartered in Clinton, New York, operates as a materials refiner, smelter, manufacturer and supplier across electronics, semiconductor, thin-film and thermal management markets. Its solder and flux product lines are established in European PCB assembly environments, and EFX 2026 represents a targeted engagement with the regional manufacturing community ahead of the broader productronica cycle.
