Inficon Leybold-Heraeus CS751-120-A IEEE-488 GPIB Plug-In Module 751-120-A

Inficon Leybold-Heraeus CS751-120-A IEEE-488 GPIB Plug-In Module 751-120-A

The Inficon Leybold-Heraeus CS751-120-A is an IEEE-488 (GPIB) interface plug-in module designed for use in Inficon Leybold-Heraeus thin-film deposition control systems. It provides an IEEE-488 bus interface between the host controller chassis and an external GPIB instrument controller or computer, enabling automated data acquisition and remote control of the deposition system. The board is labeled "Made in U.S.A." and carries the assembly reference 751-122 Rev 2.

Applications

Inficon (formerly operating under the Leybold-Heraeus name) produced a line of thin-film deposition rate and thickness monitors and multi-source deposition controllers widely used in physical vapor deposition (PVD), evaporation, and sputtering systems. The CS751 series plug-in modules slot into the mainframe chassis of these controllers and provide specific interface or measurement functions. This CS751-120-A module adds an IEEE-488 (GPIB) communications interface, allowing the deposition system to be connected to and controlled by a GPIB-equipped computer or instrument controller — a standard automation approach in semiconductor research, optical coating, and industrial thin-film production facilities from the 1980s through the 2000s. IEEE-488/GPIB was the dominant instrument bus of that era, and these plug-in interface cards were essential for integrating vacuum deposition equipment into automated process lines. They are still sought after today by facilities maintaining legacy Inficon Leybold-Heraeus deposition systems.
