Dewey Series - Stainless Steel Frame with LisStat™ ESD Cleanroom Laminate

BenchPro™ uses LisStat™ ESD laminate. This laminate covers all sides and the top of the work surface.

This LisStat™ laminate is formed around the front edge of the work surface and 3" under the front edge.

 

Each fastener sits tightly against the raw steel inside the tubes and pierces the ESD laminate in multiple places.

 

The underside of the top is bonded to a sheet of conductive aluminum.
The ESD LisStat™ laminate is bonder over the aluminum, making the entire top and bottom dissipative from every point.
The tubular steel frame is factory attached to the top by a series of screws.

Special Top Features:

1. We Use LisStat™ ESD Laminate: Uses a design which controls the static dissipation rate to meet all ANSI/BIFMA and Federal GSA standards. This laminate carry the static charge across a layer of carbon which is buried just below the surface color layer.

Some of our competitors still use brands of ESD laminate which are made conductive by dipping conventional laminate sheets into a chemical bath, then dry the sheet.

These sheets come from the laminate dipper with a label which, to paraphrase it, reads Do not clean with any products containing water, ammonia, chlorine, or soap. We have replaced hundreds of competitors tops which have lost their ESD properties over time, even though they followed all the manufacturer instructions.

2. We use ESD laminate on the top and all four edges. As surprising as it sounds most other companies either use a non-dissipative rubber strip or use nonconductive laminate on the edges. If you already have a competitors ESD bench, you can spot this by checking to see if the laminate looks identical in color, thickness and texture. If it looks different, check the surface resistivity. It won't be the same.

3. Aluminum underside: We are the only bench manufacturer to use an aluminum sheet to seal the underside of our tops and to assure conductivity. While other makers either leave the core particleboard uncovered on the bottom, paint the bottom or apply a brown paper sheet, we use the only material which completely seals out moisture, and which is 100% conductive. This is important too, as this moisture is the only reason tops warp, and leaving a nonconductive bottom sheet can cause problems in sensitive work areas.

4. Multiple grounding systems: While other brands of benches tout a very special bolt used to ground the surface of the laminate to their grounding system wires, we have eliminated this bolt (And the wires). Because all BenchPro™ bench tops are designed with a full 180 degree laminate radius on the front edge, and because the front laminate wraps under the top of the frame, we simply placed the frame where the fastening screws go through the laminate. This directs the static charge directly into the frame, which is in turn grounded by two conductors we provide for earth grounding purposes. All ESD shelves have the same grounding system.

The two front legs have banana jacks on their front edges to accept wrist strap connectors. The back of the frame has two mounting lugs to attach the two grounding wires which are included with the system. You will find this double system in evidence on every ESD bench and accessory we make.

BenchPro™ ESD work benches are not connected electrically to the floor. We use insulated floor glides so static charges will pass only through the grounding system provided, and so inadvertent charges on the floor can not pass up to the work surface and operator.

The unique characteristics of LisStat™ Static Dissipative Laminate make it ideally suited for a variety of sensitive electronic production applications.

LisStat™ Static Dissipative Laminate Sheets are designed for permanent lamination to work station surfaces.

LisStat™ meets and surpasses all standards for electrical dissipation as they apply to static control, even at low humidity levels. These standards include ANSI/BIFMA, ESDI, GSA and many others.

LisStat™ Static Dissipative Laminate Sheets are designed for permanent lamination to work station surfaces.

All BenchPro™ ESD benches are only available with ergonomic contoured front edges. This way, the ESD laminate conducts the static charges all the way to the steel frame. The steel frame has two wrist strap jacks mounted on the top of the two front legs for convenience. BenchPro™ also provides one grounding wire to take the static from the frame to either an adjoining bench or to ground.

To guarantee a static clear work area, all BenchPro™ ESD bench top have their edges laminated with the same static control laminates as used on the top, while the underside of the tops have a laminated solid aluminum sheet.
