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 (1M ) that is prop-
erly grounded to remove any static electricity that may
be charged on the body.
Ground for Work Bench
Flat Pack-IC
Be sure to place a conductive sheet or copper plate
with proper grounding (1M ) on the work bench or
other surface, where the semiconductors are to be
Fig. S-1-7
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.
