Window Glass The dust and stain on the glass window of the package degrade optical performance of CCD sensor. Keep the glass window clean by saturating a cotton swab in alcohol and lightly wiping the surface, and allow the glass to dry, by blowing with filtered dry Nz. Care should be taken to avoid mechanical or thermal shock because the glass window is easily to damage. 2. Electrostatic Breakdown Store in shorting clip or in conductive foam to avoid electrostatic breakdown. CCD Image Sensor is protected against static electricity, but interior puncture mode device due to static electricity is sometimes detected. In handing 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 pliers of or pincer. 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. 3. Incident Light CCD sensor is sensitive to infrared light. Note that infrared light component degrades resolution and PRNU of CCD sensor. 4. Lead Frame Forming Since this package is not strong against mechanical stress, you should not reform the lead frame. We recommend to use a IC-inserter when you assemble to PCB. 5. Soldering Soldering by the solder flow method cannot be guaranteed because this method may have deleterious effects on prevention of window glass soiling and heat resistance. Using a soldering iron, complete soldering within ten seconds for lead temperatures of up to 260C, or within three seconds for lead temperatures of up to 350C. 10 2001-10-15TOSHIBA TCD1707D PACKAGE DIMENSIONS WDIP22-G-400-2.54D (C) Unit in mm (Note 1) 3 11.540.8 35 (4.74mx 7450) o7t01 22 Aake ere YT 1 -e no on oo 0 3 *! oO + H ~ N lO S| | % 7 2 (Note 2) t 1.740.3 4.19+0.5 (Note 1) : No.1 SENSOR ELEMENT ($1) TO EDGE OF PACKAGE.
