GP 6 Electrostatic Discharge Prevention
Some semiconductor components, and the respective sub-assemblies that contain them, are
vulnerable to damage by Electrostatic Discharge (ESD). These components include Integrated
Circuits (ICs), Large-Scale Integrated circuits (LSIs), field-effect transistors, and other semi-
conductor chip components. The following techniques will reduce the occurrence of compo-
nent damage caused by static electricity.
Be sure the power is Off to the chassis or the circuit board, and observe all other safety pre-
cautions.
•
Immediately before handling any semiconductor components assemblies, drain the elec-
trostatic charge from your body. This can be accomplished by touching an earth ground
source or by wearing a wrist strap device connected to an earth ground source. Wearing
a wrist strap will also prevent accumulation of additional bodily static charges. Be sure to
remove the wrist strap before applying power to the unit under test to avoid potential
shock.
•
After removing a static sensitive assembly from its anti-static bag, replace it on a
grounded conductive surface. If the anti-static bag is conductive, you may ground the bag
and use it as a conductive surface.
•
Do not use freon-propelled chemicals. These can generate electrical charges sufficient to
damage some devices.
•
Do not remove a replacement component or electrical sub-assembly from its protective
package until you are ready to install it.
•
Immediately before removing the protective material from the leads of a replacement
device, touch the protective material to the chassis or circuit assembly into which the
device will be installed.
•
Minimize body motions when handling unpacked replacement devices. Motion such as
your clothes brushing together, or lifting a foot from a carpeted floor can generate enough
static electricity to damage an electro-statically sensitive device.
•
Handle IC’s and Erasable Programmable Read-Only Memories (EPROM’s) carefully to
avoid bending pins.
•
Pay attention to the direction of parts when mounting or inserting them on the Printed Cir-
cuit Boards (PCB’s).
