DANGER
Only qualified workers who are knowledgeable and have been trained to work safely with test instru-
ments and equipment on energized circuits shall be permitted to perform testing work on electrical
circuits or equipment where there is danger of injury from accidental contact with energized parts or
improper use of the test instruments and equipment.
4.01 What is ESD
!
CAUTION
STATIC ELECTRICITY can damage circuit boards and
electronic components.
• Observe precautions for handling electrostatic-
sensitive devices.
• Use proper static-proof bags and boxes.
How does ESD damage occur?
ESD can cause damage to sensitive electrical components, but is not dangerous to people. ESD damage occurs
when an ungrounded person or object with a static charge comes into contact with a component or assembly
that is grounded. A rapid discharge can occur, causing damage. This damage can take the form of immediate
failure, but it is more likely that system performance will be aected and the component will fail prematurely.
How do we prevent ESD damage?
ESD damage can be prevented by awareness. If static electricity is prevented from building up on you or on
anything at your work station, then there cannot be any static discharges. Nonconductive materials (e.g. fabrics),
or insulators (e.g. plastics) generate and hold static charge, so you should not bring unnecessary nonconduc-
tive items into the work area. It is obviously dicult to avoid all such items, so various means are used to drain
o any static discharge from persons to prevent the risk of ESD damage. This is done by simple devices: wrist
straps, connected to ground, and conductive shoes.
Work surfaces, carts and containers must be conductive and grounded. Use only antistatic packaging materi-
als. Overall, handling of ESD-sensitive devices should be minimized to prevent damage.
Service aid
ESAB can oer a number of service tools that will simplify
the service.
Antistatic service kit
Ordering no. 0740 511 001
The kit makes it easier to protect sensitive components from
electrostatic discharge.
Contents:
• A conductive mat (size 610 x 610 mm)
• A 1.5 meter long ground cable with a crocodile clip
• An adjustable wrist strap and cable with an inbuilt pro-
tective resistor
Antistatic Service Kit
What is ESD?
A sudden transfer or
discharge of static
electricity from one
object to another. ESD
stands for Electrostatic
Discharge.
