Thermal Process

thermal process

Semiconductor Manufacturing – Thermal Process The term ‘thermal process’ covers a broad scope of installations. These installation temperatures are usually higher than Plasma Processes and can go up to +300°C. In addition, thermal-based installations require not only sealing materials with a particular chemical resistance demands but also ones with good mechanical features and low compression set. Thermal Processes include: Atomic […]

What is Oxygen Cleaning

Clean Room Class 1000

What is Oxygen Cleaning / Component Cleaning? Oxygen Cleaning is a method that helps remove a variety of contaminants from components that are intended for use with either liquid or gaseous oxygen. These contaminants include oil, grease, organic or inorganic, and scale and if left alone they can cause blockages and potential risks including fires. Contaminants in an oxygen-rich system […]

Plasma Process

plasma process

Semiconductor Manufacturing – Plasma Process The plasma process is one of the most hostile for elastomers, especially those vulnerable to chemicals and/or close to the substrate or the wafer. The most hostile plasma processes for elastomers include oxygen resist strip and radical based plasmas (such as remote NF3) and chamber cleans using remote plasma sources (RPS). Every seal, especially one […]

How important is FEA Simulation in Gas & Oil

FEA simulation oil and gas vv

FEA Simulation in Gas & Oil What is FEA Simulation Finite Element Analysis (FEA) is a computer-based manipulation that evaluates how elastomer components are prone to function in real-life installations. This innovative method can ascertain how exposure to extreme temperatures and pressures and aggressive chemical circumstances can influence the components. Adequate use of FEA Simulation can eliminate the necessity for […]
