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 (1 MΩ) 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 (1 MΩ) 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.
