518 Vacuum/Pressure Furnace


The SST 518 Vacuum/Pressure furnace provides the right combination of performance and value for use in R&D labs to high mix/low volume production environments. Void-free, flux-free solder joints are reliably obtained through a carefully controlled and sequenced combination of heat, vacuum, and pressurized inert gas.
