Static Control Measures for Handling Electronic Parts
Human Awareness Levels
• We feel the discharge if it is greater than 3,500 volts.
• We hear the discharge if it is greater than 5,000 volts.
• We see the discharge if it is greater than 8,000 volts.
• By comparison, integrated circuits that are used to make
electronic circuit boards can be damaged by voltages as low
as 100 to 1,000 volts.
What Is Device Sensitivity?
Once a charge is generated, a charge can be induced from one
object onto another. This is called charge transfer. The damage is a
result of energy shifting from one charged object to another object.
Static sensitive devices are subject to damage or degradation from
Electrostatic discharge (ESD). Damage occurs because small traces and
materials cannot withstand the amount of energy surge introduced by
an electrostatic field or discharge. Damage and degradation can also
result from an electrostatic field.
Why should I care about Electrostatic Discharge?
Electrostatic discharge (ESD) costs the electronics industry millions
of dollars annually in damaged and degraded parts. A study in
Semiconductor Reliability News estimated that approximately 60%
of device failures are caused by EOS/ESD.
What Is ESD?
The contact and separation of materials creates a static charge. An
example of a common electrostatic event occurs when a charged
individual discharges to a doorknob.
The contact and separation of feet when walking across a floor creates
a charge on the individual. The discharge to the doorknob is an example
of an electrostatic discharge. The simple act of walking across a floor
can generate 15,000 volts of static electricity.
Where Do You Need Static Protection?
• Incoming inspection and test
• Stores and storage
• Transfer carts
• Kitting
• Manual and automated insertion
• Wave soldering
• Equipment assembly and test
• Packaging and shipping
• Repair stations
Device Sensitivity Threshold Levels
Generally, device sensitivity threshold levels are well
below a person’s ability to detect.
Device Type Threshold Susceptivity (Volts)

VMOS 30–1800
NMOS 60–100
GaAsFET 60–2000

Schottky Diodes 300–2500
Film Resistors 300–3000
