Indium Corporation to Showcase Proven EV Products and High-Reliability Alloys at Productronica China

Estimated reading time: 2 minutes

As a materials pioneer 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 20-22, in Shanghai.

With nearly a decade of experience in EV manufacturing and more than 10 million EVs on the road with its innovative materials, Indium Corporation will feature its Rel-ion™ suite of electrical, mechanical, and thermal solutions proven to reduce manufacturers’ time to market. Rel-ion material solutions deliver 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

Some of the Rel-ion products featured at Productronica China will include:

• Durafuse® HR: Based on a novel 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.
• Award-winning Durafuse® LT: A novel solder paste mixed alloy system with highly versatile characteristics that enable it for energy savings, high-reliability, low-temperature, step soldering, and assemblies with large temperature gradients. It also provides superior drop shock performance as compared to conventional low-temperature solders, outclassing BiSn or BiSnAg alloys, and performing better than SAC305 with optimum process setup.
• Indalloy®301 LT Alloy for Preforms/InFORMS®: A novel Pb-free alloy that enables lower processing temperatures in preform soldering compared to SAC alloys. Specifically designed for power module applications, this alloy prevents warpage in package-cooler attach scenarios without sacrificing reliability like traditional bismuth-containing low-temperature alloys. It is available in preforms, ribbon, or InFORMS®.
• Award-winning InFORMS®: Reinforced solder alloy fabrications which improve mechanical and thermal reliability, and are specifically designed to produce consistent bondline thickness for power module applications. They also address specific challenges for the power electronics industry by providing an enhanced material for the development of more reliable and higher performance modules.
• InTACK®: A no-clean, no residue, halogen-free adhesive solution developed for holding parts in place during placement and reflow processes. Designed for use in no-flux reflow applications with formic acid, InTACK® is specially formulated with high tack to hold a die, chip, or solder preform in place without movement, reducing the dependency on tooling without compromising soldering or sintering quality.
• QuickSinter®: A new approach to sinter technology. This high-metal, low-organic content approach enables fast drying and sintering times for high throughput. Both silver and copper sinter pastes are available. The portfolio includes the InFORCE™ range of pressure sinter pastes and the InBAKE range of pressure-less sinter pastes. Applications include die-attach and substrate attach in power electronics.
• Durafuse® HT: A novel design based on a novel alloy technology, designed to deliver a tin-rich, high-temperature lead-free (HTLF) paste, presenting the merits of both constituent alloys. Durafuse® HT delivers simplified processing, with no special equipment needed, and enhanced thermal cycling reliability equal to or higher than a high-Pb solder.
• Indium8.9HF Solder Paste Series: An industry-proven solder paste series that delivers no-clean, halogen-free solutions designed to achieve high surface insulation resistance (SIR) and improve stability during the printing process for high-reliability automotive electronics.
• Heat-Spring®: 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 our indium reclaim and recycle program.
