The ASMPT AD211 Plus is a fully automatic eutectic die bonding system designed for semiconductor backend manufacturing processes that require high thermal conductivity, strong electrical performance, and long-term reliability.
It is engineered specifically for metallurgical interconnect applications using AuSn or compatible solder alloys, enabling stable die attach for RF, optoelectronic, and power semiconductor devices operating under high thermal stress conditions.
It is widely used by OSATs and IDMs transitioning from epoxy die attach processes to advanced eutectic bonding solutions for high-power and high-frequency applications.
What is ASMPT AD211 Plus?
The ASMPT AD211 Plus is a fully automatic eutectic die attach platform used in semiconductor packaging to form metallurgical bonds between semiconductor dies and substrates.
It processes silicon or compound semiconductor dies such as GaAs and GaN, attaching them to leadframes or ceramic substrates using controlled reflow of AuSn or Sn-based solder systems.
Unlike epoxy die bonding, eutectic bonding creates a direct metal-to-metal interconnect, significantly improving thermal conductivity and electrical performance.
