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:
- 4x improved thermal cycling reliability compared to a solder preform-only approach
- 2x 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
