Instructions for Handling
Semiconductors
Electrostatic breakdown of the semiconductors may
occur due to a potential difference caused by electro-
static charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a grounding band (1M
Ω
) that is prop-
erly 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 semiconductors are to be
placed. Because the static electricity charge on cloth-
ing will not escape through the body grounding band,
be careful to avoid contacting semiconductors with
your clothing.
