Precautions
1.3 ESD Precautions
Some semiconductor components, and the respective sub-assemblies that contain them, are vulnerable to damage by
Electro-Static DISCHARGE (ESD). These components include Integrated Circuits (ICs), Large-Scale Integrated
circuits (LSIs), field-effect transistors, and other semiconductor chip components. The following techniques will
reduce the occurrence of component damage caused by static electricity.
Be sure the power is off to the chassis or circuit board, and observe all other safety precautions.
■ Immediately before handling any semiconductor components assemblies, drain the electrostatic 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, place it on a grounded conductive surface. If
the anti-static bag is conductive, you may ground the bag and use it as a conductive surf ace.
■ 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 protecti ve material from the leads of a replac ement de vice, touch the protecti v e
material to the chassis or circuit assembly into which the device will be installed.
■ Minimize body motions when handling unpackaged 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 electrostatically sensitive device
■ Handle IC’s and EPROM’s carefully to avoid bending pins.
■ Pay attention to the direction of parts when mounting or inserting them on Printed Circuit Boards (PCB’s).
