If you work with electronic components or devices, you know how important it is to protect them from electrostatic discharge (ESD). ESD is the sudden release of electricity between two objects that have different electric potentials, such as a person and a metal surface. ESD can cause serious damage to sensitive electronic components or devices, such as microchips, circuit boards, or hard drives, by creating sparks, overheating, or short-circuiting them. ESD can also affect the performance and quality of the products, leading to product failure, customer dissatisfaction, and increased costs.
One of the best ways to prevent ESD from harming your products and your workplace is to use appropriate ESD protection measures, such as ESD chairs. ESD chairs are specialised chairs that prevent the build-up and discharge of static electricity. They are typically used in industries that handle electronic components, such as computer manufacturing or repair, telecommunications, and aerospace.
What are ESD chairs?
ESD chairs are chairs that have a low electrical resistance, which means they allow the electric charge to flow across the chair at a controlled rate. ESD chairs can be made of different materials and components, depending on the level of protection and functionality required. The main features of ESD chairs are:
- Conductive seat and back: The seat and back of the chair are made of conductive materials, such as rubber, vinyl, or fabric, that contain conductive fibres or additives. These materials create a static dissipative surface that does not create or hold any charge, and allows the electric charge to flow across the chair at a slow rate.
- Conductive base and castors: The base and castors of the chair are made of metal or plastic, that are coated or mixed with conductive materials, such as carbon or graphite. These materials create a conductive path that connects the chair to the floor, and allows the electric charge to flow fromthe chair to the ground.
- Grounding point: The chair has a metal stud or snap that connects the chair to the ground. This creates a closed circuit that allows the electric charge to flow from the chair to the ground, without affecting the user or the item.
- Wrist strap: The chair has a wrist strap that wraps around the user’s wrist and connects to the grounding point. This ensures that the user is at the same electric potential as the chair and the item, and prevents any static charge from building up on the user’s body.
How do ESD chairs work?
ESD chairs work by creating a path for the electric charge to flow from the source to the ground. The source can be a person, a tool, or an item that has a different electric potential than the chair. The ground can be an earth connection, such as a metal rod or a wall socket, that provides a safe outlet for the electric charge.
To use ESD chairs effectively, you need to connect the chair, the user, and the item to the ground. This can be done by using the wrist strap, the grounding point, and the conductive base and castors. These components create a closed circuit that allows the electric charge to flow from the source to the ground, without affecting the item or the user.
By using ESD chairs, you can prevent ESD from damaging your electronic components or devices, as well as protect yourself and others from the harmful effects of ESD, such as electric shocks, burns, or fires. You can also comply with the ESD standards and regulations that are set by various organisations, such as the International Electrotechnical Commission (IEC), the British Standards Institution (BSI), or the Electrostatic Discharge Association (ESDA).
Why do you need ESD chairs?
ESD chairs are important for several reasons, such as:
- Protecting electronic components or devices: ESD chairs prevent ESD from damaging electronic components or devices by reducing the flow of electric charges and diverting them away from the sensitive items. This ensures the optimal performance and quality of the products, and avoids product repair or replacement costs.
- Protecting yourself and others: ESD chairs also protect yourself and others from the harmful effects of ESD, such as electric shocks, burns, or fires. ESD can also interfere with the functioning of medical devices, such as pacemakers, or cause explosions in flammable environments, such as gas stations. ESD chairs can prevent these hazards by providing a safe and comfortable working environment.
- Complying with ESD standards and regulations: ESD chairs also help you comply with the ESD standards and regulations that are set by various organisations, such as the IEC, the BSI, or the ESDA. These standards and regulations specify the requirements and guidelines for ESD control and prevention in different industries and applications. ESD chairs conform to the EN 61340-5-1 standardAd1, which is the most widely recognised and accepted standard for ESD protection.
ESD chairs are a vital part of ESD protection and prevention. They prevent the build-up and discharge of static electricity, which can cause serious damage to electronic components or devices, as well as yourself and others. They also reduce costs, increase efficiency, and increase longevity of the products. Therefore, ESD chairs are essential for anyone who works with static sensitive items, whether as a manufacturer, a seller, or a buyer.
