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 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 ground-

ing band, be careful to avoid contacting semi-con-

ductors with your clothing.
