3.4.3. PREVENTION OF DAMAGE DUE TO ELECTROSTATIC DISCHARGES
It is essential to guard against electrostatic discharges during an intervention concerning electronic components,
sub-assemblies and complete systems.
Elimination of the danger due to ESD requires a combined team effort. By complying with the following
instructions, you can substantially reduce the potential damage caused by ESD and ensure long-term reliability
for the robot.
• Inform the staff of the risks stemming from ESD.
• Know the critical zones sensitive to ESD.
• Know the rules and procedures to deal with ESD.
• Always carry components and boards in a tray to protect them from electrostatic charges.
• Always ground yourself before working on a workstation.
• Keep non-conducting equipment (static charge generators) away from components and boards.
• Use tools providing protection from ESD.
STÄUBLI workstation
To handle electronic cards, STÄUBLI workstations are given a grounded coating that dissipates static electricity.
An anti-static bracelet is required to handle boards or electronic components.
Work zones
Remove objects that generate static electricity charges from the work area, such as:
• plastic cups
• polystyrene
• notebooks
• plastic files and document holders.
Printed circuits, boards and electronic components must be kept in anti-static bags.
Anti-static wrist strap
Use an electrostatic wrist strap connected to the frame of the controller or to the frame of the arm and the ground
during all handling of boards or components. The wrist straps are supplied as part of the standard equipment for
the robot.
CAUTION:
Use an electrostatic wrist strap and an anti-static mat connected to the cabinet during
all handling of boards or components.
