MOS INTEGRATED CIRCUIT HANDLING
Some North Star PC boards use some MOS-type IC's. These parts
are identified as such in the instructions, MOS devices can be
damaged by static electricity discharge. so special handling is
necessary to protect them. Handle MOS devices as little as
possible and avoid touching the pins. Place the conductive foam
or tube which contains the MOS device onto the PC board before
removing the device from the foam or tube. Also, be sure both
hands are touching the foam or tube when the device is removed
from the foam or tube.
Once a MOS device has been installed in a PC board, handle the
board as little as possible. Of course, never insert or remove
any IC while power is applied to the board, and never remove or
insert a PC board while power is applied to the motherboard.
