AVS-4000 Automated High Vacuum Furnace


The SST AVS-4000 is a high-vacuum multi-atmosphere sealing furnace that is custom designed for automated sealing operations as one element of an integrated production system. The furnace is fully operational at temperatures up to 500°C, vacuum levels as low as 10-7 Torr and automatic selection and electronic control of up to three process gasses.

The AVS-4000 benefits include:

  • Robotic tooling load and unload from in-line transfer stations
  • Combination of capabilities: void-free soldering, high vacuum MEMS package sealing, hermetic package sealing
  • Fixturing to precisely locate package components
  • Application of precise thermal profiles in vacuum and positive inert gas pressures


Void-Free Die Soldering. Void-free die and substrate solder attach is used to create a uniform thermal interface for high-reliability microelectronic devices.

High Vacuum MEMS Package Sealing. Advanced MEMS devices require internal vacuum levels on the order of 1 millitorr over the life of the device. Sealing of these MEMS packages requires specialized thermal processing in high vacuum system.

Hermetic Package Sealing. Hermetic package sealing uses solder or glass to create a barrier to moisture which will damage sensitive electrical circuit components.
