Product Description
Au88Ge12 Solder Preforms
Features:
- Eutectic solder with a melting temperature of 361 ºC
- Good thermal and electrical performance
- Good thermal fatigue resistance
- Low contact resistance
Description:
Au88Ge12 as a kind of gold-based eutectic solder has a melting temperature of 361 ºC . Au88Ge12 has the advantages of low vapor pressure, low contact resistance, good adhesion to substrate, high electrical and thermal conductivity, etc. It is
considered as an ideal sputtering and evaporation source, and is widely used in GaAs MESFET to form ohmic contacts. As a kind of eutectic solder, Au88Ge12 is also used in the field of die bonding in the packaging of transistors, integrated circuits and other components.
