▶ Clean residual thermal paste from the CPU surface using a lint-free cloth
and store the CPU in a save place.
CAUTION
CPUs are extremely sensitive to electrostatic discharge and therefore
must always be handled with care.
▶
After a CPU has been removed from its protective sleeve or from
its socket, place it upside down on a nonconducting, antistatic
surface.
▶
Never push a CPU over a surface.
Installing the CPU
CAUTION
When replacing a system board
▶
Use a magnifying glass (recommended) to inspect the socket
spring contacts for damages from different angles. Do not use the
spare system board if any irregularities are visible. Possible
damages:
– Contact spring is bent backwards upon itself
– Contact spring tip position is shifted or out of alignment
▶
Never try to fix bent contact springs. Doing so may result in loss of
electrical performance and reliability.
