Static sensitive devices
CMOS devices operate at very high impedance levels. Therefore, any static that builds up on
you or your clothing may be sufficient to destroy these devices if they are not handled properly.
Use the following precautions to avoid damaging them:
CAUTION Many CMOS devices are installed in the Model 2400. Handle all semicon-
ductor devices as being static sensitive.
• Transport and handle ICs only in containers specially designed to prevent static build-
up. Typically, you will receive these parts in anti-static containers made of plastic or
foam. Keep these devices in their original containers until ready for installation.
• Remove the devices from their protective containers only at a properly grounded work
station. Ground yourself with a suitable wrist strap.
• Handle the devices only by the body; do not touch the pins.
• Ground any printed circuit board into which a semiconductor device is to be inserted to
the bench or table.
• Use only anti-static type desoldering tools.
• Use only grounded-tip solder irons.
• Once the device is installed in the PC board, it is normally adequately protected, and
you can handle the boards normally.
