1190 System board assembly

Important notices for handling the system board
When handling the system board, read the following:
• The system board has an accelerometer, which can be broken when several thousands of G-forces
are applied.
Note: Dropping a system board from a height of as little as six inches so that it falls flat on a hard bench
can subject the accelerometer to as much as 6000 G's of shock.
• Be careful not to drop the system board on a bench top that has a hard surface, such as metal, wood, or
composite.
• Avoid rough handling of any kind.
• At every point in the process, be sure not to drop or stack the system board.
• If you put a system board down, be sure to put it only on a padded surface such as an ESD mat or a
corrugated conductive material.
