Instructions for Handling
Semi-conductors
Electrostatic breakdown of the semi-conductors may
occur due to a potential difference caused by electrostatic
charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a grounding band (1M
Ω
) that is properly
grounded to remove any static electricity that may be
charged on the body.
2. Ground for Workbench
Be sure to place a conductive sheet or copper plate with
proper grounding (1M
Ω
) on the workbench or other
surface, where the semi-conductors are to be placed.
Because the static electricity charge on clothing will not
escape through the body grounding band, be careful to
avoid contacting semi-conductors with your clothing.
