Method for ESD protection for laboratory chairs with armrests

Disclosed is a method for electrostatic discharge (ESD) protection for laboratory chairs with armrests. Benefits include improved performance and improved cost effectiveness.

Background

         Many companies offer special ESD-protected chairs prepared for use in hardware laboratories, but they are very expensive. They are also unreliable when the user is wearing a good insulator, such as cotton, which requires the direct grounding of the user’s skin.

         Another disadvantage of the laboratory chairs is that many chairs do not have armrests.

         Conventional solutions include:

•         Strap with a metal ribbon that is grounded, but the user must remember to touch it before any work with hardware. This solution is inexpensive but unreliable because the person can easily forget to touch it.

•         Special tables or table surface covers with a special material that is manufactured from highly conductive material. This solution is reliable but expensive.

•         Special ESD-protected chairs, which are often without armrests and, therefore, uncomfortable. This solution is expensive and unreliable because the user can sit down without contacting the ESD-protected area.

Description

         The disclosed method is ESD-protection for laboratory chairs with armrests. A plastic strap contains glue on the bottom and a metal ribbon on the top that is connected to a ground (see Figure 1). The plastic strap is adhered to the armrest with the glue, and the groun...
