Indium to Showcase Proven EV Products and High-Reliability Alloys at Productronica China
March 26, 2025 | Indium CorporationEstimated reading time: 2 minutes
As a global materials supplier and trusted partner in electric vehicle (EV) and e-Mobility manufacturing, Indium Corporation® is proud to showcase its high-reliability alloys and soldering solutions at Productronica China, March 26-28, in Shanghai, China.
With 10 years of expertise in EV manufacturing and more than 10 million electric vehicles using its advanced materials, Indium Corporation will showcase its Rel-ion™ product suite. These products offer reliable electrical, mechanical, and thermal solutions designed to accelerate manufacturers’ time to market. Rel-ion™ material solutions enhance reliability by:
- Eliminating non-wet opens and head-in-pillow defects
- Preventing dendritic growth by meeting stricter surface insulation resistance requirements
- Preventing solder delamination with precise bondline control and increased creep and fatigue resistance
- Reducing hot spots-induced voiding through improved thermal efficiency
Indium Corporation will focus on the following featured products:
- Durafuse® LT is an award-winning solder paste alloy system with versatile characteristics that enable energy savings, high reliability, and low-temperature step soldering. It is ideal for assemblies with large temperature gradients and large BGAs with complex warpage profiles. Durafuse® LT delivers superior thermal cycling and drop shock performance, outperforming conventional low-temperature solders like BiSn or BiSnAg alloys, and it even outperforms SAC305 with optimal process setup.
- Durafuse® HR, based on novel solder paste alloy technology, delivers enhanced thermal cycling performance (-40°C/125°C and -40°C/150°C) and superior voiding performance for high-reliability automotive applications. It also offers reduced solder joint cracking and increased shear strength.
In addition, Indium Corporation will showcase the following products of high-reliability materials powering sustainability:
- Indalloy®301LT for Preforms/InFORMS® is a novel Pb-free alloy that enables lower reflow processing temperatures compared to SAC alloys, preventing delamination and reducing warpage in package-attach soldering applications.
- InTACK® is a no-clean, no residue, halogen-free adhesive solution developed for holding parts in place during placement and reflow processes.
- Durafuse® HT is an innovative Pb-free solution designed to deliver a high-temperature lead-free (HTLF) paste 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 a high-Pb solder.
- 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. It also offers a sustainable solution due to the company’s indium reclaim and recycle program.
- InFORCE™ is a series of high-reliability pressure sinter pastes, offering copper and silver formulations with excellent thermal conductivity. Optimized for printing, large-area sintering, and low-temperature processing, they offer innovative solutions for advanced die-attach and package applications.

Knocking Down the Bone Pile: Revamp Your Components with BGA Reballing
10/14/2025 | Nash Bell -- Column: Knocking Down the Bone PileBall grid array (BGA) components evolved from pin grid array (PGA) devices, carrying over many of the same electrical benefits while introducing a more compact and efficient interconnect format. Instead of discrete leads, BGAs rely on solder balls on the underside of the package to connect to the PCB. In some advanced designs, solder balls are on both the PCB and the BGA package. In stacked configurations, such as package-on-package (PoP), these solder balls also interconnect multiple packages, enabling higher functionality in a smaller footprint.
