Vacuum furnace
max. 500 °C, max. 15 psig | MODEL 3140/3150 SST International

The 3140 and 3150 are high vacuum furnaces offered by SST International for high-reliability microelectronic package assembly. Packages are hermetically sealed with very low internal gas pressures and moisture levels. Prior to package sealing, integral getters may also be activated to ensure long-term internal package vacuum levels.

Both the 3140 and 3150 systems provide precise automatic control of both heating and cooling. Temperatures up to 500 °C are easily achieved in vacuum levels below 1 x 10-6 torr and in positive inert gas pressures up to 15 psig. The 3140 utilizes a cryogenic vacuum pumping system for the most effective pumping of water molecules. The 3150 utilizes a turbomolecular drag pump for the best pumping of hydrogen gas molecules. Both systems are backed by an oil-free roughing pump. Digital vacuum level gauging is provided to monitor and control vacuum levels. Machine control is provided by an embedded control system operating in a Microsoft Windows® environment. An unlimited number of process profiles can easily be created and stored in the controller. Run data is archived for quality control and off-line data analysis. Internet and intranet network connectivity is available as an option, permitting remote monitoring, troubleshooting and maintenance capabilities. Custom-designed resistive graphite heating fixtures (ordered separately) are matched to user application requirements for optimum system performance. An automatically controlled linear motion stage provides component separation during thermal processing and getter activation.
