The manual specifies: Degas only when pressure is below 1 x 10⁻⁵ Torr. Degassing at higher pressures will cause arcing and permanent damage. One 5-minute degas per week is sufficient for clean systems.
The MKS Astron 2L is a popular mass flow controller (MFC) used in various industrial and research applications. As with any complex device, understanding its operation, configuration, and maintenance is crucial for optimal performance. The MKS Astron 2L manual serves as a comprehensive guide for users to familiarize themselves with the device's features, installation, and troubleshooting procedures. This essay aims to provide an overview of the MKS Astron 2L manual, highlighting its key components, operating principles, and practical implications.
is a self-contained, high-performance Remote Plasma Source (RPS) used extensively in semiconductor fabrication . It functions primarily as a designed for chemical vapor deposition (CVD) and atomic layer deposition (ALD) chamber cleaning. By utilizing a highly efficient low-field toroidal plasma design paired with an integrated switching power supply, the unit dissociates gases like Nitrogen Trifluoride ( NF3NF sub 3
The manual also includes a troubleshooting section, which helps users diagnose and resolve common issues with the Astron 2L. Users are provided with a list of possible causes and solutions for problems such as incorrect flow rates, valve malfunction, and communication errors. Regular maintenance procedures, such as cleaning and replacing the sensor, are also outlined in the manual.
MKS recommends periodic refurbishment (every 6–12 months) of high-wear components like electronic circuit boards and plasma blocks. mks astron 2l manual
) to deliver reactive fluorine atoms to the process chamber. This guide serves as a comprehensive technical overview and operational manual reference for technicians maintaining units (including part numbers AX7650 , AX7651 , and AX7657 ). Technical Specifications & Operating Parameters
Over time, adsorbed gases on the grid can cause outgassing, leading to false high-pressure readings. The manual details two degas methods:
Secure the unit to a rigid support frame capable of handling its weight and the mechanical vibrations from surrounding vacuum pumps. Electrical and Communication Connections
Flow Argon through the system for ~10 seconds to clear residual gases. The manual specifies: Degas only when pressure is
