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.
Ground for Human Body
Be sure to wear a grounding band (1MΩ) that is prop-
erly grounded to remove any static electricity that may
be charged on the body.
Ground for Work Bench
Fig. S-1-6
Be sure to place a conductive sheet or copper plate
with proper grounding (1MΩ) on the work bench or
other surface, where the semiconductors are to be
placed. Because the static electricity charge on the
clothing will not escape through the body grounding
band, be careful to avoid contacting semiconductors to
clothing.
