Products and Services

Solder Materials

Indium Corporation is one of the most prominent names in solder technology. Its solder product portfolio includes:

• Solder Paste: Used in surface-mount technology (SMT) assembly, these pastes combine powdered solder alloy with flux to attach components to printed circuit boards. Indium offers formulations for a wide variety of applications, including low-temperature, halogen-free, and high-reliability requirements.
• Solder Preforms: Precisely shaped pieces of solder used where controlled volumes of solder are required, common in die attach, sealing, and thermal interface applications.
• Solder Wire and Cored Wire: Products used in manual soldering, rework, and automated wire-fed soldering processes, often containing flux cores for improved wetting.
• Solder Spheres and Bumping Materials: Used in ball grid array (BGA) packaging and advanced semiconductor interconnection.
• Solder Ribbon, Foil, and Fabricated Shapes: Custom forms for specialized industrial and electronic uses.

Fluxes

The company produces a broad line of soldering fluxes, including liquid fluxes, tacky fluxes, and gel fluxes. These are engineered to promote wetting, remove oxides, and enable reliable solder joints. Indium's flux offerings include no-clean, water-soluble, and rosin-based chemistries designed for different cleaning and reliability requirements.

Thermal Interface Materials

Indium Corporation offers thermal interface materials (TIMs) used to manage heat in electronic devices. Its metal-based thermal interface products, including indium-based TIMs and solder-based thermal solutions, help transfer heat away from processors, power devices, and other heat-generating components. These materials are valued for their high thermal conductivity and reliability in demanding applications.

Indium and Specialty Metals

As its name suggests, the company is a leading producer and supplier of indium metal and indium-based compounds. These materials are used in a wide range of applications, including:

• Indium metal for alloys, seals, and thermal applications
• Indium oxide and indium tin oxide (ITO) materials used in displays, touchscreens, and photovoltaic cells
• Compound semiconductor materials and precursors
• Low-melting-point and fusible alloys used in specialized industrial applications

The company also handles a variety of other metals, including gallium, tin, bismuth, silver, gold, and germanium, offering refining and reclaim services for many of these materials.

Semiconductor and Advanced Packaging Materials

Indium Corporation supplies materials tailored to the semiconductor packaging industry, including die-attach materials, sintering pastes, and advanced interconnect solutions. Its silver sintering technology supports power electronics and high-reliability applications where superior thermal and electrical performance is required.

NanoFoil and Reactive Materials

Through its reactive material technologies, the company offers products such as NanoFoil, a nanotechnology-based material that produces controlled, localized heat when activated. This enables joining of materials without exposing surrounding components to high temperatures, useful in specialized bonding applications.

Sputtering Targets and Deposition Materials

Indium Corporation produces sputtering targets and evaporation materials used in thin-film deposition processes for semiconductors, displays, optical coatings, and photovoltaics. These materials support the fabrication of advanced electronic and optical devices.

Refining and Reclaim Services

The company provides metal refining and reclaim services, allowing customers to recover valuable metals such as indium, gallium, and precious metals from their manufacturing scrap and byproducts. This supports sustainability efforts and cost recovery for customers working with high-value materials.
