Service Manual vii

Electrostatic Discharge (ESD) Precautions

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 semiconductor chip components. The following techniques will reduce the occurrence of component damage caused by static electricity.

Be sure the power is of f 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 surface.

■ Do not use freon-propelled chemicals. These can generate electrical ch arges sufficient to

damage some devices.

■ Do not remove a replacem ent 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 unpackaged replacement de vices. 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 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).
