• 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 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 and 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 ICs 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 circuit boards.
