An EPA could be one small workbench or an entire manufacturing plant.
In an EPA all industrial equipment such as flooring, workbenches, chairs, trolleys, shelving storage and small parts storage should all be grounded to safely disperse static electricity. There are also a static dissipative workwear items that can be worn by employees, which we discuss in more detail below. A technician walking to their workbench can generate enough static electricity to damage an electrical component.
ESD workbenches are suitable for static controlled areas and have worktops which are grounded for the safe discharge of static electricity. If the application involves the use of electrical components, then an anti-static workbench is an essential piece of equipment to help limit damage caused to these components during the work process.
Neostat worktop — has a dual-layer surface covering made from rubber. It has a dissipative top layer and a conductive bottom layer, it is this that creates a safe path to ground. Surface resistivity of Neostat is 10 5 — 10 7 ohms. Lamstat worktop — has a plastic laminate static dissipative surface. This surface is also suitable for work involving soldering, heat and chemicals. Surface resistivity of the Lamstat is of 10 6 — 10 8 ohms. Therefore, numerous accessories have been developed to help assist in preventing and ESD event.
These accessories include items such as:. ESD matting is beneficial in many ways. As we mentioned above walking alone can create static electricity. However, ESD matting can help to disperse this electricity. These mats have electrically conductive carbon fibres throughout. Consequently, the ESD flows at a slower rate across the surface of the mat which in turn neutralises it. It covers the requirements for designing, establishing, implementing, and maintaining an ESD control program.
It may appear that introducing ESD protection is very extreme. However, today all manufacturers of electronic equipment will implement very strict regimes to ensure that product failures in manufacture are reduced to the minimum and that long term reliability is as high as possible. By implementing these measures product reliability is now at a very high level. New developments in electronics technology combined with manufacturing techniques including ESD protection all combine to enable much higher levels of reliability than were previously possible.
These can broadly be grouped into the following main areas: ESD protection at circuit and assembly design: In order that electronics circuits can survive electrostatic discharges encounter in normal use, it is essential that protection is built in to the circuitry. This is normally important on any connections to the outside world.
It is also necessary that sub-assemblies and boards have some measure of ESD protection so that when they are handled, the boards or sub-assemblies have some level of ESD protection. Build and test equipment in an EPA: When building electronics equipment, it is necessary that the components, and subassemblies are all handled in a way that prevents them from being exposed to ESD.
Often companies these days treat all components as static sensitive devices. Within an EPA strict controls are employed to ensure that ESD dissipated and that the environment provides protection for any electronics components and assemblies.
Store components in an ESD controlled area: It is not only necessary to ensure that electronics assemblies are built within an environment in which ESD protection is paramount. It is also necessary to ensure that all components are stored and transported within an environment in which ESD protection is implemented. Similarly the ESD protection must also be applied to any sub-assemblies that are stored.
