1-3-4 Instructions for Handling
Semi-conductors
Electrostatic breakdown of the semi-conductors 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 (1MΩ) that is prop-
erly grounded to remove any static electricity that may
be charged on the body.
2. Ground for Workbench
(1) Be sure to place a conductive sheet or copper
plate with proper grounding (1MΩ) on the work-
bench or other surface, where the semi-conduc-
tors are to be placed. Because the static electricity
charge on clothing will not escape through the
body grounding band, be careful to avoid contact-
ing semi-conductors with your clothing.
