Indium “InFORMS” at IMAPS 2016
Indium Corporation is to feature its reinforced indium and solder alloy fabrications, InFORMS, at IMAPS 49th International Symposium on Microelectronics (Oct. 10-13 in Pasadena). InFORMS is said to provide engineers with an enhanced material for the development of new, or the improvement of existing applications.
InFORMS are reinforced solder preforms that maintain a constant bondline thickness, thus significantly improving thermal cycling reliability. This is a key requirement in many applications, including die-attach and baseplate-attach for IGBTs.
According to the company, in one study where InFORMS were used to solder a DBC and baseplate of an IGBT, the following was achieved:
- 4X improved thermal cycling reliability compared to a preform-only approach
- 2X improved thermal cycling reliability compared to a 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
