The Thinking Test
Engineer's Guide to
ESD Control
iest tri

Electrostatic forces are at work in your labs, chambers and fixtures, often affecting your test procedures and results. Since they are from invisible fields they go mostly ignored. Catastrophic failures, uncontrolled contamination or unforeseen results can be avoided through a practical understanding of the science surrounding the strange world of static charge; ESD, EMI, and ESA.

There are lots of standards and lots of rules to follow to create an ESD program. However, to apply them properly, understanding of the science of electrostatic force is essential for your particular application. Improper use of the standards and rules will result in improper specification, ineffective results, and wasted time and money. Specifying more than you need to do also is potentially a large money waster.

This course will provide the participant with a practical understanding and approach for recognizing, measuring, and assessing static charge, and minimizing its harmful effects in their own fixtures, chambers, labs, and critical environments (even on a space vehicle).

The participant will leave this training course with a step-by-step, solid understanding that will help them look at their own applications in a new way. They will be able to identify potential electrostatic issues and find cost-effective solutions.

  • Elements of a Static Charge Control Program – material selection, grounding, the importance of dissipative material, packaging, ionizers. Selecting tools and designing fixtures to be ESD safe.
  • Building an ESD – Safe Work Station.
  • People – Protecting against static charge issues on workers.
  • Standards and Handbooks on Static Charge Control – Mid Std 1686C and ANSI-ESD S2020-2007 (replaces 1686C), IEST RP CC022. Using S2020 to establish your ESD control program.
Who should attend?

I need to understand the science behind protecting my sensitive components because:
  • I am a test and manufacturing professional who has labs or processes which can be affected by ESD.
