ESD Workbench C6036301

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. Accordingly its performance is critical within the overall facility.

The ESD workbench can be seen to consist of a number of different elements:

• Static dissipative work surface: The primary element of any ESD work bench is the static dissipative work surface.

• Shelves: As static can build up anywhere on a work bench, 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 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 work benches 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 work bench, 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 work bench assembly.
