The ESD workbench can be seen to consist of a number of different elements:
Shelves: As static can build up anywhere on a workbench, it is essential that all elements of the bench are static dissipative. As items, either electronics assemblies or tools may be placed here the shelves need to be part of the ESD protected area. Also if tools are placed on a non-ESD dissipative surface, attract static, and then they are used to work on an electronics assembly, then the damage could result.
Metalwork: While the metalwork itself is conductive, the paint used is not normally conductive. For an ESD workbench, it is necessary to use static dissipative paint to prevent any sudden discharges.
Cupboards: Many workbenches have cupboards attached to them as an integral element for tidy storage. In view of the fact that electronics assemblies or other items such as tools for working on the assemblies may be stored in these cupboards, it is essential that the cupboard conforms to the same ESD standards as all other areas. Shelves should have static dissipative surfaces and any painted metalwork should have a static dissipative paint finish.
ESD wrist straps: When working at an ESD workbench, it is necessary to ensure that the operator is also held at the same potential so that no discharges occur. ESD wrist straps are generally used for this.
Wiring: It is necessary to ensure that all static dissipative surfaces, wrist straps, etc are all connected to a common grounding point, and wired in a suitable manner. It is essential that this is achieved effectively and in the correct manner from the viewpoint of electrical safety.
Monitoring system: With wires such as the connections to ESD wrist straps, etc being in almost constant use there will be periodic failures. One method that has been adopted is to test ESD wrist straps and their wires each day. However, when a problem is detected, it is possible that the operator has been causing damage to assemblies since the last time the ESD wrist strap was tested. To overcome this problem, continuous monitoring systems are available which are considerably more satisfactory. These are typically incorporated into the ESD workbench assembly.
Care and maintenance of the ESD workbench
With a good dissipative surface on an ESD workbench it is necessary to use and maintain it for it to provide a long effective life. Apart from testing which is covered in the paragraph below, there are a few simple steps that can be taken to ensure the ESD workbench provides a long and useful life.
Avoid damaging the ESD dissipative surface of the workbench with sharp objects as these can significantly reduce the effectiveness of the surface, particularly if small areas become isolated by cuts, etc.
Clean the surfaces periodically to prevent the build-up of grease or other layers that will impede the static dissipation. A plain cotton rag or cloth, with diluted ammoniated detergent, is ideal. Using this, ensure that all dirt films are removed from the surface. It is always best to consult the manufacturer's literature for the best methods for their particular surface.
Never use wax-based cleaners or solvents that may attack the surface or modify its properties.
Never use abrasive cleaners. This can include abrasive cleaning agents as well as abrasive cleaning pads such as kitchen scourers. These can remove or damage the ESD dissipative surface and considerably impair its action.
It is worth implementing a regular care and maintenance schedule as dirt and grease can build up on an ESD dissipative surface over time and its performance gradually reduce. As it is difficult to visibly detect any performance degradation, and any effects may come on gradually and not be noticed, the only way to overcome this is to regularly clean and maintain the surface. Testing should also be incorporated into this schedule.
Testing of the ESD workbench
In addition to cleaning of the work surface, periodic testing of the ESD workbench is required. This ensures that after repeated use of the connections and general infrastructure of the bench, everything is within its required tolerances and no breaks of connections are present.
Often monitors are used to ensuring that wrist straps and their connections are properly operational, but periodically a complete electrical test of the bench including its ESD performance is needed.
ESD workbenches are widely used for research and development laboratories, production test areas, service and repair areas and many more. The use of a proper ESD safe Workbench is necessary to ensure the ESD protected area is completely operational.

Electrostatic discharge is to occur and it can be dangerous for personnel and damage parts and materials. A workbench is a key area for many ESD protected areas. The use of an ESD workbench should provide some protection against this, keeping personnel, components and devices safe.
What is the ESD workbench?
The ESD workbench provides many of the elements for the basis of an ESD protected area. Although many other elements are needed, having a good ESD workbench is key.
Not only does a typical ESD workbench provides a static dissipative surface on which to work, but it also provides suitable connection points for other elements of the static protected environment.
Benefits of the ESD Workbench
The key element to an ESD workbench is the use of a static dissipative surface, which provides an electrical path to ground to allow for the controlled dissipation of any static potential from materials that come into contact with the surface. It is also recommended that, along with a static dissipative worktop, personnel are grounded which can be done through the use of a wrist strap that has a path to ground. Also, other accessories might be necessary such as ESD table mats and floor mats or ESD footwear, depending on the tasks being performed and the work area.
An ESD workbench is essential for all electronic applications and is suitable for use as an assembly or repair bench in the electronic industry. They are also designed as individual work stations in warehouses, factories, clean rooms and any other controlled areas. When working with ESD sensitive materials and parts it is important that all measures are taken to protect personnel, this can easily be achieved through the use of an ESD workbench and static dissipative accessories.
Static dissipative surface of the ESD workbench
In order to provide the correct environment for an ESD workstation, an ESD work bench should have a static dissipative surface. A further reason for having a high resistance dissipative surface rather than a fully conductive surface is that of safety. If high voltages were present in a system, then accidentally touching a conductive work surface and a high voltage source could be dangerous. Accordingly, safety precautions necessitate that a high resistance dissipative surface is used.
An ESD workbench is one of the central elements within a full ESD protected area for use within an electronics manufacturing or repair facility. It is necessary that the ESD workbench is able to provide a full protected environment for any electronics assemblies that require work on the ESD workbench.
