Product Description

RoHS-Compliant In97Ag3 Solder Preform for Medical Electronic Devices

In97Ag3 Solder Preforms

Features:
- Lead-free eutectic solder
- Melting temperature 143ºC
- Good ductility and thermal conductivity
- Good fatigue resistance

Description:
In97Ag3 is a kind of low temperature lead-free solder with a melting temperature of 143ºC . In comparison with Sn-based solder, In97Ag3 can inhibit the corrosion of Au or Ag. Meanwhile, In97Ag3 possess low melting temperature, excellent fatigue resistance, good ductility and thermal conductivity, making it suitable for soldering of glass and ceramics.
