PRECAUTIONS FOR USE OF CCD IMAGE SENSOR 1. Static Electricity CCD Image Sensor is protected against static electricity, but inferior puncture mode device due to static electricity is sometimes detected. In handling the device, it is necessary to execute the following static electricity preventive measures, in order to prevent the trouble rate increase of the manufacturing system due to static electricity. a. Prevent the generation of static electricity due to friction by making the work with bare hands or by putting on cotton gloves and non-charging working clothes. b. Discharge the static electricity by providing earth plate or earth wire on the floor, door or stand of the work room. c. Ground the tools such as soldering iron, radio cutting plier or pincette. It is not necessarily required to execute all precaution items for static electricity. It is all right to mitigate the precautions by confirming that the trouble rate within the prescribed range.

2 Window Glass

As the dust and station on the glass window of the package will cause black flow on the picture, never fail to clean the glass surface before using. (Blow compressed vapor, and wipe off the dust, and dirt with soft cloth or paper slightly moistened with alcohol). Fully take care for the handling of the device as the window glass will break or a strong friction is given to the window glass surface. 3. Incident Light CCD image sensor has sensitivity in a wide range zone of light wave length, but its characteristics willsometimes widely change when used with long wave length input light outside the visual light zone. 1999-06-22 13/14
