Electrostatic Discharge Protection Mats

Dycem Contamination Control Floor Mats have an extra benefit – they have the properties to protect from ESD and occurrences.

What is Electrostatic Discharge (ESD) ?

Electrostatic discharge (ESD) is caused by a number of factors and is commonly generated by the contact of materials. It can be produced by everyday occurrences, such as a person picking up a piece of polystyrene packaging or walking across a carpet; it can even be caused by dust in the environment.

Positive and negative charges are stored in materials and carried by people. The human body is capable of storing a charge up to 25,000V. This charge is then dissipated (ESD) through the receiving object as the current seeks an unimpeded path. An object’s metal chassis will often act as the conductor for the static to strike, but it can occur through other materials.

The majority of people encounter electrostatic charges or discharges (ESD) through commonplace processes such as the crinkling feeling after emptying clothing from a tumble dryer, scuffing or walking across a carpet and grabbing a door handle, holding onto metal stairway railings, escalators or more awkwardly when shaking hands with other people and receiving a shock.

To offer an explanation In layman’s terms, ESD occurs when two materials rub together causing friction and thus positively charging the material. Once your body comes into contact with this the positive charge is transferred to you and escapes you when possible resulting in what is commonly referred to as an “electric shock“.

Additionally, other aspects such as dust particles, are often given less emphasis within ESD and static dissipation discussions on charged surfaces.

Dust is one of the main enemies that can trigger ESD occurrences.

The introduction of dust contamination and contaminated particles into a highly sensitive environment such as semiconductor manufacturing or cleanrooms can be detrimental to production.

Electrostatic Discharge Protection Sign

In present times, with the increased use of technology and reliance, however current day discussions on ESD mainly surround electronic device and semiconductor manufacturing.

The increase in device sensitivity and technology within the electronics industry moving more towards nanotechnology, this heightens the measures manufacturers, processors and fabricators need to set in place to ensure protection for ESD safe working environments.

These are imperative to ensure a safe operating environment for workers and perhaps more importantly to protect the product quality and product yield. The presence of ESD charge can compromise the integrity of an electrical appliance, semiconductor or chip wafer impacting its functionality or worse destroying them completely.

One of the main solutions to avoid damage to ESD sensitive equipment is to create an environment that inhibits the build-up of static and provided Electrostatic discharge protection.

This can include the exclusion of highly charging materials from the controlled area and use of grounding mats, such as Dycem’s contamination control mats or flooring, which are proven to dissipate static at 108 ohms and reduce the damage it can cause.

WHAT IS STATIC DISSIPATION?

Static control is also especially critical in the manufacture of electronic assemblies and components such as circuit boards and semi-conductors.

As it is almost impossible to avoid static-generating actions the best way to avoid damage to ESD sensitive equipment is to create an environment that inhibits the build-up of static. This can include the exclusion of highly charging materials from the controlled area and using grounding mats, such as Dycem’s contamination control mats or flooring, which are proven to dissipate static at 108ohm and reduce the damage it can cause.

Regardless of how stringent the regulations are, particles WILL be present within controlled or cleanroom environments. These can occur through personnel, production equipment or the process itself.

Dycem Workzone ESD Mats offer electrostatic discharge protection in place to reduce static charge risks and particularly within cleanroom environments, these include extensive use of grounding static dissipative and conductive materials such as ESD floor mats.

Our anti-static floor mats help to avoid the detrimental impacts of ESD charge. Naturally tacky due to the way they are made, the use of Dycem cleanroom sticky mats for their ESD protection benefits has been essential for Cleanrooms and other facilities that need to reduce the risk of ESD and Static Dissipation.

Available in a range of colours and customisations, Dycem mats are to be walked upon or have wheel traffic rolled across and naturally aims to remove dust and particles prior to entering the clean and critical areas. Using disposable options do not allow for this.
