Grounding Hardware

Worksurface and floor mats are most commonly grounded with a dedicated wire that is connected to electrical ground. Traditionally, the connection between the mat and wire is made with a snap. Snap connections can become electrically intermittent or accidentally disconnected, causing the worksurface to lose its connection to ground. To improve this connection, Desco offers…

ESD worksurfaces, such as mats, are typically an integral part of the ESD workstation, particularly in areas where hand assembly occurs. Carts or shelves where ESD sensitive items are stored (without ESD shielding) would also be treated as an ESD workstation. The purpose of the ESD worksurface is two-fold: To provide a surface with little to…

Using snaps has long been the most common way of making a grounding connection (wrist straps, ground cords, etc) in ESD control products, but snaps have some drawbacks. Snaps can be easily unsnapped or damaged, and they are not normally used for making an electrical connections. Desco manufacturers a better design that is more durable and cannot be easily disengaged.

The design used in Desco’s dome style ground cords is made with a 10mm (0.395 in.) male threaded snap. Dome style ground cords are sometimes called a Floor Mat Ground, but they can be used on work benches too. With a screw and washer installed from the backside of the mat, the ground cord can be secured to the mat to reduce the opportunity for the mat to become ungrounded.
