ESD Control Program Basics: Building Toward ANSI/ESD S20.20 Compliance
Jul 06, 2026
Most ESD failures do not come from one dramatic zap. They come from a control program that looked fine on paper and quietly stopped working.
Here are the fundamentals of an ESD control program and the standard that holds it together.
What an ESD Control Program Is
An ESD control program is the documented, verified system a facility uses to protect electrostatic-discharge-sensitive devices from damage during handling, assembly, test, and packaging.
It is not a wrist strap and a sign on the wall. It is a coordinated set of controls, responsibilities, and verification activities that work together — and that have to be checked, not assumed.
ANSI/ESD S20.20: The Backbone
ANSI/ESD S20.20 is the widely adopted standard for ESD control programs. It defines the requirements for establishing, implementing, and maintaining a program — covering grounding, personnel and equipment controls, packaging, and the compliance verification that proves the program is working.
Most serious ESD programs are built around S20.20 because it gives structure to something that otherwise drifts into guesswork.
The Core Elements
- Grounding and bonding — the common reference everything else depends on
- Personnel controls — wrist straps, footwear, and garments, used correctly
- Worksurfaces and equipment — dissipative surfaces, tools, and fixtures
- Ionization — for charges on insulators that grounding cannot remove
- Packaging and handling — protection during movement and storage
- Compliance verification — periodic testing that proves controls still work
Why Programs Fail
The controls are usually not the problem. The verification is. A wrist strap that tested fine last quarter may be failing now. A worksurface ground may have come loose. Humidity may have shifted charge behavior.
Without disciplined compliance verification, a program degrades silently — and the damage it lets through is often latent, passing inspection and test only to fail in the field months later.
Why This Needs a Knowledgeable Owner
S20.20 does not run itself. It needs someone who understands not just the rules but why they exist, how controls fail, and how to read verification data and act on it. That is exactly the competency iNARTE ESD certification develops.
Final Thought
A control program is only as good as its weakest verified control. Build it around ANSI/ESD S20.20, verify it relentlessly, and put someone in charge who genuinely understands ESD.
