Indium Corporation provides a myriad of materials for Light Emitting Diode (LED) manufacturing. From gallium trichloride for MOCVD precursors to thermal interface materials, no other materials company provides so many solutions in so many layers of the ever-advancing LED.
Indium Corporation specializes in supplying In and Ga compounds at high purity, in large volume, and around the globe.
Indium Corporation is the world’s largest supplier of metal TIMs for LED assembly. We offer a wide selection of metal-based TIMs for reflow or compression. Our patented Heat-Spring® compressible interface material at 86W/mK conductivity can solve many thermal interface issues. The standard pack for Heat-Springs® is tape & reel and it is designed for both automated or hand assembly applications.
Our TIMs are used like a standard thermal pad. They have no residue and zero outgassing properties. Heat-Springs® are provided in custom or standard off-the-shelf shapes.
Surface Mount Assembly and Solder Fortification
Indium Corporation solder pastes for LED assembly offer ultra-low voiding and clear residues. We also manufacture and supply solder preform chips in tape & reel. Solder preforms chips add extra bulk to solder starved joints. We also provide solder preform washers and flux-coated preforms for soldering connectors to LED packages.
Wave Soldering Materials and Rework
Indium Corporation offers a full line of wave soldering and rework materials for LED assembly. Here are the recommended materials. If you need help selecting the right materials for your process you can view our whole line of wave solder fluxes here.
For LED companies needing high temperature
die-attach materials, Indium Corporation is a global provider of solder paste, wire, and high purity AuSn preforms for fluxless die-attach.
For companies in need of materials for bumping wafers or soldering pre-plated dies for flip-chip, Indium Corporation provides "semiconductor grade" solder pastes and fluxes.
NanoBond®, a joining process using NanoFoil®, is used to bond the thermal pad on LEDs to the heat-sinking substrates. NanoBond® eliminates the need for the conventional reflow of LEDs, resulting in improved brightness and color, and extended lifetime. When combined with conventional assembly techniques, NanoBond® produces superior thermal performances as compared to thermal epoxies.
NanoFoil® is a self-contained, localized heat source that can be used to solder bond electronics packages to substrate materials. NanoFoil® is a RoHS compliant material consisting of hundreds of alternating nanoscale layers of aluminum and nickel. Once activated, the heat can melt adjacent solder layers to join components together with minimal thermal exposure of the components.

Indium Corporation’s gold/tin solder paste gives manufacturers the versatility to produce high volumes of scaled-up product on demand without committing to component designs that would limit further research and development.
Many applications require high temperature, Pb-free alloys for product reliability. Indium Corporation offers a wide variety of solder and braze alloys.
80Au20Sn solder paste and preforms both have particular attributes that make them ideal for certain bonding applications. We take a look at how your production furnace determines which form you use, and how material characteristics help aid in production.
