Indium Corporation manufactures die-attach solder paste, such as Indium8.9-LDA, for vacuum soldering. Indium Corporation's IGBT die-attach solder paste can be screen printed or stencil printed and is easy to clean.
Indium Corporation also provides solder ribbon and solder preforms for die-attach applications. Tape & reel packaging allows preforms to be advanced and placed with speed and accuracy. Semiconductor-grade ribbon and preforms come in ultra-pure alloys and adaptable packaging, such as tape & reel, custom spools, and cartridge packs, to increase productivity, performance, and efficiencies.
All material is recyclable and reclaimable.
Materials for Vacuum Soldering
Direct Bonded Copper (DBC) or Substrate-Attach
Indium Corporation's soldering materials for DBC-attach include solder ribbon and solder preforms. Manufactured for purity, they offer low voiding when reflowed in air or vacuum.
InFORMS® were developed to solve the non-planar solder joint issue common in substrate bonding. InFORMS® are reinforced solder alloy fabrications that ensure parallel soldering at a predetermined bondline thickness.
NanoFoil® solders a component in nanoseconds without using a reflow oven. NanoFoil® provides a localized heat source that enables high strength, high conductivity bonding between most combinations of materials. NanoFoil® emits enough energy to solder 25-150+ micron bondlines. In addition, tin-plated NanoFoil has been used to solder gold-plated substrates together without the need for a reflow oven or any plating. For more information, visit www.indium.com/nanofoil/.
Materials for Substrate-Attach
Heat-Sink or Baseplate-Attach
Removing heat from a power module is important for ensuring interconnect reliability. Indium Corporation's Heat-Spring® material is a non-reflow compressible metal pad with a thermal conductivity of 86W/mK. Unlike some of the more typical thermal interface materials, such as thermal grease, Heat-Springs® do not pump out or bake out.
Heat-Springs® can be engineered and optimized for difficult applications and a wide variety of surface conditions. Minimum pressure required is 25-45psi and minimum thickness is 75 microns. Custom packaging includes tape & reel and tray packs. See our application note entitled "Heat-Spring® Metallic Thermal Interface Materials for Application to Infineon Technologies AG PrimePACK IGBT Modules" for information on how Indium Corporation's Heat-Springs® performed in testing against a comparable flat indium shim and two typical silicone-based thermal grease materials.
Liquid metal is another material that can be used as a thermal interface. Liquid metal is RoHS-compliant and has a thermal conductivity of 40W/mK and a contact resistance of virtually zero.

Recently I heard about two of my friends (and co-workers) taking on an additional responsibility in the electronics industry. Tim Jensen (Senior Product Manager for Engineered Solder Materials) and Maria Durham (Technical Support Engineer for Semiconductor and Advanced Assembly Materials) have become…
It sounds bad for me to say this, but I have a lot of SMT magazines cross my desk and, honestly, the solder paste articles rarely draw my interest. I work in a world of solder preforms and that’s really where my mind is at, currently. A recent exception is a paper written by Eric Bastow (Assistant…
