What Are the Criteria for Selecting an Esd Chair?

As a must-have for working in electrostatically sensitive areas, the ESD Chair is widely used in clean rooms, microelectronics manufacturing, communications, aerospace and other fields. It not only has the functions of an ordinary chair, but also performs well in anti-static and has long-lasting properties. This chair is usually cleverly composed of three parts: anti-static packaging fabric, a stable support part and practical casters.

The basic material of the ESD Chair is electrostatically conductive nylon, which is carefully made into wheels and then connected to a metal stainless steel support frame to ensure effective connection with the anti-static floor or floor and the supporting grounding system, thereby achieving effective protection against static electricity. During use, the wheels of the ESD Chair are grounded by contacting the ground with the electrostatic conductive shoes, thereby achieving the effect of electrostatic release.

When choosing a high-performance ESD Chair, we should pay attention to the following two points:

Comply with ESD industry standards, which involves the volume and surface resistivity of the chair being controlled between 1×10^5Ω and 1×10^9Ω, and the resistance to ground must be less than 1×10^9Ω. In addition, the effectiveness of the chair's long-term surface resistance and ground resistance is crucial, and the casters will not generate dust or fade when they collide with the ground to ensure electronic cleanliness and the best environmental effect.

In precision clean workshops, ESD Chairs must strictly control dust-free. This is because dust pollution is intolerable for such workshops. Therefore, dust-free and odor-free should be maintained during use to adapt to these strict requirements.

What is the difference between ESD Chair and ordinary chairs?

The main differences between ESD Chair and ordinary chairs are reflected in two aspects. First, in terms of application scope, ESD Chair is not only suitable for various dust-free laboratories and special anti-static environments, but also can be used in daily life environments, while ordinary chairs are mainly limited to daily life and work scenes. Secondly, from the working principle, ESD Chair is a must-have for electrostatic sensitive areas. It is equipped with ESD cushions and metal accessories. Through the mutual cooperation of these components, the electrostatic charge generated during contact can be effectively introduced into the ground, thereby ensuring excellent electrostatic discharge function. In addition, its surface does not contain oxides, and all materials used have been rigorously tested in the laboratory to ensure that they meet the standards for use in clean rooms and anti-static areas. In contrast, ordinary chairs focus more on the comfort of sitting and have no special requirements for materials and functions.

ESD Chairs usually do not have armrests, because increasing the contact surface may increase the chance of static electricity. In contrast, ordinary chairs are often designed with armrests, which has become a habit, making people feel uncomfortable without armrests and not knowing where to put their hands.

The difference between ESD Chair and ordinary chairs is of great significance in practical applications. When choosing, we should make wise decisions based on actual needs and situations to ensure that work efficiency and quality can be significantly improved in special work areas.
