Indium Features InFORMS Reinforced Solder Preforms At APEC 2017

Indium will feature its reinforced solder alloy fabrications, InFORMS, at APEC 2017, March 26th-30th, in Tampa, Fla.

InFORMS are reinforced solder preforms that increase lateral strength and stability. As a result, improved thermal cycling reliability can be achieved.


In one study where InFORMS were used to solder a DBC to the baseplate of an IGBT, the following were achieved:

  • Four improved thermal cycling reliability compared to a solder preform-only approach
  • Two improved thermal cycling reliability compared to a solder preform + Al wirebond stitch approach
  • Low-voiding of <1%
  • Lower cost of ownership – an InFORM is a drop-in replacement for a standard preform or solder paste, requiring no additional process steps or equipment
