Professional development training course

Elastomer technology and seal design for the semiconductor industry

A one or two day professional development course

Introduction

Seals are often taken for granted at the design stage of complex equipment but are frequently identified as being responsible for failure in critical sealing applications. The use of cost effective, high performance sealing components is crucial to the optimal functioning of sealing systems. Improved sealing performance advanced sealing designs, optimal material selection and extended service intervals, can all combine to offer a lower cost of ownership.  A sound understanding of the complex factors involved in successful sealing is essential for people who specify, design, manage, operate or maintain equipment in the semiconductor industry. PPE can offer a range of sealing training courses, tailored to suit market or individual needs. 


The courses for the Semiconductor market are available at three different levels:

  • Basic Course (lunch-and-learn workshop). ~2 hours in length, normally provided at customer site.
  • Intermediate Course. 1 day. This course can be attended at international conference venues, at PPE or at a customer site.
  • Advanced Course. 2 days. This course is run at PPE, England.

This professional development course takes the format of an interactive workshop and is tailored specifically to the requirements of the delegates attending. It is based on disciplines such as mechanical design, physical properties, thermal expansion, chemical resistance, purity and plasma resistance. All of these factors are considered during the course and how they effect the decision making process with regard to types of seal, seal materials and sealing applications. This allows a forum for discussion on individual sealing issues, which are used as real-life case studies during course.

Course aim

The course will focus on real-life applications. Its aim is to ensure all participants acquire a fundamental understanding of elastomer sealing technology and design within the Semiconductor Industry. The course will include case studies with practical suggestions on implementing improvements to the delegates own applications.

Course objectives

At the end of the basic training session, delegates will be able to:

  • Ask appropriate questions of elastomer manufacturers in order to compare and evaluate the suitability of elastomer
  • materials.
  • Define the range of elastomers available and understand their inherent strengths and weaknesses.
  • Specify the optimum elastomer material for any given application, and how to achieve cost savings by informed
  • seal material selection.
  • Estimate how differences in service environment may affect seal performance.
  • Identify the causes of seal failure and take appropriate action to eliminate future occurrences.

At the end of the 1-day intermediate training seminar, delegates will be able to:

  • Ask appropriate questions of elastomer manufacturers in order to compare and evaluate the suitability of elastomer materials.
  • Define the range of elastomers available and understand their inherent strengths and weaknesses.
  • Specify the optimum elastomer material for any given application, and how to achieve cost savings by informed seal material selection.
  • Write a robust sealing specification whilst avoiding over-specification.
  • Combine the latest materials technology with modern design techniques to design a more competitive product.
  • Estimate how differences in service environment may affect seal performance.
  • Identify and diagnose potential sealing problems early thereby extending preventative maintenance (PM) cycles and reducing any possible downtime.
  • Identify stress-induced chemical attack, and understand how this can be overcome.
  • Specify the causes of seal failure and take appropriate action to eliminate future occurrences and potential warranty claims.
  • Compare and contrast a range of seal designs and their pitfalls.
  • Understand how O-ring seals are manufactured.
At the end of the advanced training course, in addition to the intermediate points opposite, delegates will be able to: 

  • Explain the effects of entropy and viscoleasticity with regard to elastomers.
  • Understand a wide variety of failure mechanisms and how they can be identified using the most modern analytical
  • techniques.
  • Understand how different grades of materials are compounded, and how the different ingredients can affect a seals
  • performance, e.g. plasma etch rates, particulates etc.
  • Explain the mechanisms commonly used in an attempt to predict seal life; i.e. compression set, stress relaxation etc.
  • Review of the Arrhenius Equation and how its application relates to sealing performance over time.
  • Demonstrate the effects of temperature on an elastomeric seal, both in terms of heat ageing as well as strength-attemperature.
  • Undertake practical tests related to thermal expansion at elevated temperatures.
  • Show the effects of cross-link density, and how this can be measured experimentally.
  • Understand the differences related to the design of seals used for low-pressure applications, both in terms of material
  • selection and seal design.
  • Specify different seal geometries based upon application conditions, e.g. D-seals, omega seals etc.
  • Apply Newton’s Third Law to seal design.
  • Carry out finite element analysis (FEA), and a practical example of creating mathematical models using ANSYS®.

Who should attend?

This training seminar is designed for;
  • Project and Design Engineers involved in seal design or seal specification
  • Semiconductor Wafer Production, Service & Maintenance Engineers
  • Technical Staff and Program Managers
  • Quality Managers and Engineers
  • Business and Operational Managers
  • Technical Purchasing
  • Material Engineers
  • Engineering Apprentices/Trainees/Graduates

Personal impact

Attendance at the training seminar will result in individuals developing their knowledge, understanding and skills in various aspects of elastomer technology, seal design and how they impact on applications they are involved with. Delegates will be able take this knowledge and apply it in their day-to-day activities to achieve cost savings, more robust designs and display to their own customers a greater depth of knowledge.

The seminar is based on a combination of interactive activities - group and individual exercises, case studies, hands-on problem solving tasks and discussions - along with formal technical input from the course trainers. Each delegate recieves a certificate of attendance and a course handbook which provides a valuable source of information for future reference.
