LEISTER LABOR “S” ESD
SERIES
A nozzle grounding system capable of dissipating static
electricity through a common workstation ground.
The system equalizes the electrical surface
conductivity of the nozzle and the air hose by incorporating a low
OHM conductor between the two surfaces.
The air hose is made of carbon-impregnated
silicone and is conductive.
The ground cord incorporates a 1-mega OHM
resistor. The resistor will provide isolation between the operator
and the absolute ground.
The resistor also reduces the electrical
conductivity of the overall ground circuit. Conductivity of the
circuit is not less than 1 x 10 6 OHM and therefore
becomes static dissipative.
Operational testing showed a constant
dissipation of static electricity at 5.6 micro amps.
These tools feature a nozzle grounding system
capable of dissipating static electricity through a common
workstation ground.
The system equalizes the electrical surface
conductivity of the nozzle and the air hose by incorporating a low
OHM conductor between the two surfaces.
The air hose is manufactured of
carbon-impregnated silicone and is conductive.
The grounding cord, which connects the tool to
a common workstation earth ground, incorporates a 1-mega OHM
resistor.
The resistor will provide isolation between
the operator and absolute ground (a necessary safety feature in case
the ground should become positively charged).
The resistor also reduces the electrical
conductivity of the overall ground circuit. Conductivity of the
circuit is not less that 1 x 10 6 OHMS and therefore
becomes static dissipative.
Operational testing showed a constant
dissipation of static electricity at 5.6 micro amps.
This design allows the tools to be utilized in
a static free environment without adding to the variable electrical
potential of the workstation. |
