Indium Corporation Introduces Ultra-Thin Precision AuSn Preform

Indium Corporation has expanded its portfolio of precision preforms with an ultra-thin AuSn preform designed for semiconductor laser applications, where thermal management has become a challenge.

Indium Corporation’s AuLTRA® ThInFORMS™ are 0.00035” thick (0.00889mm or 8.89μm) 80Au20Sn preforms that improve the overall operational efficiency of high-output lasers. AuLTRA® ThInFORMS™ help combat common issues such as:

  • Shorting—reduced solder volume inhibits wicking up the die, minimizing the risk of shorting
  • Poor thermal transfer—the ultra-thin 0.00035” preform reduces bond-line thickness (BLT), thus improving thermal transfer and increasing the longevity and performance of the device.
