In addition to our webinar program, we work with industry organizations and media to support them with technical content and advance the industry.

Q. How are you meeting the advanced needs of the global electronics assembly materials market?

To us, our motto of From One Engineer to Another® is more than a phrase; it is a commitment to collaborating with customers and partners on the challenges facing our industry. In support of that, Indium Corporation’s team has continued to innovate with new materials and processes to meet the demands of new products that are currently or will shortly enter the market. Throughout the pandemic, this included investing in R&D and engineering. We also installed more manufacturing tools and analytic capabilities than any previous year. To accommodate this increased activity, we increased our manufacturing footprint in virtually all of our facilities, created a new 42,000 sq. ft. headquarters, and added new manufacturing facilities in India (2020) and Malaysia (2021).

Q. What is driving the evolution of lead-free solders? Your offerings and focus into this technology?

When the world was moving toward green manufacturing, lead-free soldering—originally driven by RoHS (Restriction on the use of Hazardous Substances in electrical and electronic equipment) of Europe —was becoming the mainstream for the electronics industry, and Sn-rich alloys—including SnAgCu, SnAg, and SnCu—had been prevailing for more than a decade. While the electronics industry keeps advancing rapidly toward miniaturization, two important drivers are dictating the evolution of lead-free solders: low cost and high reliability. Indium Corporation has a long legacy in developing lead-free solder solutions designed to meet our customers’ needs. This has included the development of Indium8.9HF Solder Paste, a lead-free product that delivers superior printing and voiding performance, to our ongoing efforts with the Die Attach 5, or DA5, consortium (composed of Infineon Technologies, Bosch, STMicroelectronics, NXP Semiconductors, and Nexperia) to develop high-temperature, lead-free alternatives to traditional lead-containing solders. Indium Corporation’s efforts have led to the development of numerous high-temperature solder products, including BiAgX®, a high-temperature lead-free solder paste, as well as the QuickSinter® silver sintering paste, and Durafuse™ HT, a high-temperature alloy system.

Q. Indium Corporation is a world-leader in solder paste and SMT assembly. How do you find the market out in India? Challenges and scopes.

Indium Corporation works tirelessly through the research and development of our products to prove again and again that materials science changes the world by enabling a large variety of future technologies. These include, but aren’t limited to, novel thermal materials removing heat from high- performance computer chips and ultrafine solder powders of novel alloys, allowing the creation of the tiny solder joints needed for mobile and wearable devices. As a percentage of our sales, India is relatively small today, but the growth rate of both our business and the electronics market in India is tremendous. We are also adding more technical support resources in addition to our new factory in Chennai. We see a bright future for India in the global electronics supply chain going forward and we are proud to be a part of it. We look forward to continuing to participate in local organizations and events.

Q. PCB market in India is quite vibrant and bullish, Indium’s focus on the PCB assembly sector and how dynamic it has become with advanced technology demand (smaller, sophisticated, and more powerful devices) dominating the market?

Indium Corporation has continued to develop materials designed to meet the evolving challenges of the PCB industry. The demands for smaller, more reliable, and low-temperature solutions create exciting opportunities for the development of innovative enabling technologies. For example, some of Indium Corporation’s newest offerings, such as CW-232, a flux-cored wire for robotic and laser soldering applications, features additional wetting power for higher throughput as well as exceptional post-soldering cleanliness. Where traditional low-temperature solders can product brittle joints, Durafuse™ LT is a low-temperature alloy system designed to provide high- reliability in low-temperature applications that need to reflow below 210°C. PicoShot® NC-5M is specifically engineered to support smaller components that require precision materials. Its innovative formulation provides exceptional jetting performance and its unique oxidation barrier promotes complete powder coalescence during reflow to eliminate graping and similar reflow issues.

Q. Any flagship solution you want to highlight for our Indian reader and industry, benefits, pricing, etc.?

We have excellent relationships with our customers as part of our commitment to the collaboration inherent in From One Engineer to Another® and we continue to advance our materials technology. There are almost always trade-offs in solutions, e.g., cost vs. reliability, assembly vs. performance, etc., and we help our customers make those decisions in order to help them achieve the lowest cost of ownership. We have a strong technical team near our customers and a strong development and engineering team at our sites to advance our technology. Almost all of our product development is driven by solving our customers’ challenges.

Q. Lastly, how important is the Indian market for Indium and your future plans for the Indian market?

We are seeing India becoming much more important in the electronics industry due to both domestic demand as well as increasing participation in global supply chains. As a result, we are investing more heavily in the region with local manufacturing and more technical support personnel along with developing local partners. This investment includes the opening of our first manufacturing facility in India, located in Chennai. We are in the process of ramping up production with tremendous support from our customer base in the region. We already have more expansion plans planned for 2021.
