Develop an Excellent ESD Control Program for Your Facility
ESD Standard Information
Z-Mar Technology specializes in static control and ESD protection for electronics manufacturing. We have ESD certified engineers, technicians, and other specialists to help enhance your ESD control program to be in compliance with ANSI/ESD S20.20-2014.
Z-Mar representatives can perform an ESD audit at your facility and verify that you are in accordance with ANSI/ESD S20.20. We can also provide training to ensure that your ESD control products are being used properly.
Many find our ESD audits helpful prior to an upcoming customer or ISO audit. Our written report can help improve your productivity, quality, and customer satisfaction.

Why We Use ESD Standards
Importance of Training and Audit Programs
The benefits to be gained from regular auditing procedures are numerous.
It's the sudden transfer (discharge) of electricity from one object to another. ESD is commonly known as "static electricity." Here are some examples:
ESD seems harmless, but it can damage electronic components (parts) and assemblies.
ESD usually results when two objects touch, rub, or slide together, or are separated. Even two charged objects coming close together--without touching--can cause ESD.
ESD is often caused by people.
Three Rules to Follow
Unfortunately, yes. However, ESD damage can be significantly reduced if everyone follows proper ESD control procedures.
The amount of static is measured using an Electrostatic Field Meter. Z-mar has a variety of Field Meters available.
The conductive range is from 10^0 - 10^5.
The dissipative range begins at 10^5 and goes to 10^12.
At this point (10^12), the insulative range begins.
An insulator is any material that prevents the flow of electrons.
Silver static shielding bags offer a metalized layer called a Faraday cage that shields the contents from a static charge. An anti-static bag is made of a neutral material that does not generate nor shield from static.
The ANSI S20.20 standard says that an insulator must be a minimum of 12". An easy measurement to determine a good distance is an arm's length.
All of these products are insulators and really should not be present at an ESD-safe workstation, however, if they MUST be there, then it is necessary they be kept a minimum of 12" away from ESD devices.
Anti-static tape is made especially for use in controlling static around ESDS devices. It does not generate a static charge, unlike other tapes. These tapes include Scotch and Kapton tapes.
If you are measuring the surface resistivity of an object, then use a Surface Resistivity Meter. Some call it a Megger or a Megohmmeter. Z-mar offers these meters.
