CLINTON, N.Y., May 21, 2026 – As an industry leader in innovative materials solutions for semiconductor packaging and assembly, Indium Corporation® will showcase its high-reliability portfolio of products at the IEEE Electronic Components and Technology Conference (ECTC), May 26-29, in Orlando, Florida.
The company will feature the following products:
Flip-Chip Flux:
- NC-809 is a no-clean, ultra-low residue, ball-attach flux. Its dual-purpose engineering provides high-tack characteristics for flip-chip applications with strong wetting power for ball-attach applications.
- WS-446HF Flux is a robust, halogen-free, water-wash flux designed to provide one simple solution to complicated applications, especially those with a single cleaning step, for both BGA ball-attach and flip-chip processes. Its powerful activator system promotes good wetting on even the most demanding substrate metallizations, such as Cu OSP, ENEPIG, and ENIG. Its rheology is suitable for dipping flip-chip applications, as well as pin transfer or printing BGA ball-attach applications, for sphere sizes 0.25 millimeters and above. WS-446HF helps to improve production yield by minimizing non-wet open defects, missing balls, and electrochemical migration.
Sintering Paste:
- InBAKE™29 is a Cu sinter paste developed for power discrete die-attach applications and applications requiring high thermal conductivity, high electrical conductivity, and high service/operating temperatures. It is specifically designed for pressureless, batch oven sintering.
- SiPaste® C312HFis a cleanable solder paste formulated for fine-aperture printing applications. This material exhibits optimum transfer efficiency with consistent printing stability after continuous use and a long stencil life of at least four hours without dry-out. Its benign, non-corrosive residue can remain post-reflow without cleaning or be easily removed with semi-aqueous or saponifier technology.
- InFORCE®29 is a range of pressure Cu sinter pastes for applications where high reliability and high thermal conductivity are critical. Applications for InFORCE®29 include die-attach for Si and SiC power devices and substrate-attach of power modules directly to coolers.
Thermal Solutions:
- Durafuse® HT is an innovative high-temperature lead-free paste that is ideal for discrete power electronics devices. Durafuse® HT can “drop in” to the current high-Pb die-attach paste process, with no special equipment needed. Functional performance and thermal cycling reliability are both equal to or higher than those of a high-Pb solder.
- Solder Thermal Interface Materials (sTIMs) deliver superior heat dissipation and high thermal conductance for power-dense devices exceeding 1,000 watts. Optimized for BGA package applications, sTIMs enable low-void, high-reliability performance across multiple reflow cycles, ensuring thermal stability. Unlike fluidic solutions, they ensure reliable end-of-life performance, preventing failures common with greases. Ideal for portable electronics, sTIMs enhance battery life, reduce cooling fan size, and minimize heat-sink mass while maintaining RoHS compliance and supporting sustainability initiatives.
- Heat-Spring® is a compressible, non-reflow metal TIM ideal for TIM2 applications. These indium-containing TIMs offer superior thermal conductivity over non-metals, with pure indium metal delivering 86W/mK in all planes. Because of its solid metal state, Heat-Spring® avoids pump-out and bake-out problems and offers a sustainable solution through the company’s metals and compounds reclaim and recycle program.
- Heat-Spring® HSx is a compressible, non-reflow metal TIM designed for large-area dies with warpage of 200 microns or more. It delivers 16W/mK thermal conductivity at just 20psi, making it ideal for test heads with clamping forces of 30psi or less. Available in thicknesses from 300microns to 1 millimeter, it can be customized with or without a diffusion barrierto prevent die staining.
