Grounding Methods
Method 1 (Grounding via ground cords)
1. Desco recommends using a common point ground cord when
grounding via ground cords. Most common point ground cords
will ground your ESD worksurface and provide banana jack
ground points for two wrist straps.
2. A common point ground should be installed at each workstation
and should be connected directly to a verified “green wire”
equipment ground. Only one groundable point should exist on a
worksurface.
Figure 5. Common point ground for each workstation.
3. Wrist straps should never be grounded through a worksurface,
as the added resistance of the worksurface material will
prevent the wrist strap from operating properly.
Figure 6. Proper grounding of wrist straps.
4. Per ANSI/ESD S1.1, a current limiting resistor in the wrist strap
ground cord is recommended. If other than a one megohm
resistor, special marking in red is required.
For additional information on grounding we recommend Desco
Technical Bulletin TB-2007.
Groundable Point Installation
1. Before installing a groundable point on your mat you must first
determine whether you will need a snap socket or stud, the
type of snap hardware and the location.
2. Desco has three types of 10mm (.395") field installable mat
grounding snaps. The first type is a screw-on snap kit Desco
item number 09864 Universal Snap Kit.
A. Determine the position of the grounding snap (one only
per mat) and type of fastener you will be installing (socket
or stud). Take precautions not to cut your hand, and punch
a hole through the material with a small Phillips screwdriver
or awl.
B. Remove the release paper from the circular common point
ground label and affix it so that it aligns with the hole on the
material.
C. Select one of the screws as follows:
Material less than .100" thick - short screw
Material greater than .100" thick - long screw
D. Insert the screw through the top on the snap stud or socket,
the washer, the label and the material. Affix the assembly
with the conical nut supplied with the kit and tighten down
the screw using a Phillips screwdriver.
E. Remaining will be either a 10mm stud or socket, and either
a long or short screw to be discarded or saved for another
application.

Figure 7. Three kinds of snaps.
3. The second type of mat grounding snap is the push and
clinch snap. This snap is designed for use with any type of
soft mat material: dissipative, conductive or multi-layered. It is
recommended for use with three-layered material, because it
provides excellent contact with the internal conductive scrim
layer. It is recommended that before inserting this snap, the
mat be punctured with a sharp tool where the snap will be
placed. Take precautions not to cut your hand. Push and Clinch
snaps are available as a snap stud as item #09861 and as a
snap socket as item #09863.
A. Remove the release paper from the circular label and
affix it onto the mat material in the desired location.
B. Center the prongs on the snap assembly with the label.
Apply pressure to the snap until the prongs come through
the back of the mat, then clinch over prongs to secure snap
as shown in Figure 9.
