All pixel signals can be read independently via the vertical shift register and horizontal shift register. With their small lens and WLCC-type flat package, it is possible to make ultra small color camera easily.

Package Breakage 2. Electrostatic Damage In order to prevent the package, the lens holder, and the lens from being broken, follow the instructions below : 1) The CCD is a precise optical component and the package-base material is ceramic. Therefore, ø Take care not to drop the device when mounting, handling, or transporting. ø Avoid giving a shock to the package. Especially when leads are fixed to the socket or the circuit board, a small shock could break the package more easily than when the package isn’t fixed. 2) When adjusting the focus, screw the lens holder to the circuit board before soldering the leads. At that time, make sure to use a circuit board with plenty of strength, and to avoid the package and the lens holder from being broken, the following screw and clamp torque are recommended. ø Recommended mounting screw : Ø1.7 tapping screw (B-tight type), Length, L = the thickness of the circuit board + 5 mm ø Recommended clamp torque : 0.012 N·m [however, when the thickness of the circuit board is thinner than t = 2.0 mm] 3) If any damage or breakage occurs on the surface of the lens, its characteristics could deteriorate. Therefore, ø Do not hit the lens. ø Do not give a shock large enough to cause distortion. ø Do not scrub or scratch the surface of the lens. – Even a soft cloth or applicator, if dry, could cause dust to scratch the lens. As compared with general MOS-LSI, CCD has lower ESD. Therefore, take the following anti-static measures when handling the CCD : 1) Always discharge static electricity by grounding the human body and the instrument to be used. To ground the human body, provide resistance of about 1 M$ between the human body and the ground to be on the safe side. 2) When directly handling the device with the fingers, hold the lens holder and do not touch the lead. 3) To avoid generating static electricity, a. do not scrub the device with cloth or plastic. b. do not attach any tape or labels. c. do not clean the device with dust-cleaning tape. 4) When storing or transporting the device, put it in a container of conductive material. 3. Dust and Contamination Dust or contamination on the surface of the lens and the inside of the lens holder could deteriorate the output characteristics or cause a scar. In order to minimize dust or contamination on the device, take the following precautions : 1) Do not remove the lens from the body. Especially when adjusting macro, be careful not to remove the lens by turning it counterclockwise too much. 2) Do not touch the surface of the lens with the fingers. If dust or contamination gets on the surface of the lens, the following cleaning method is recommended : ø Handle the built-in lens CCD in a clean environment such as a cleaned booth. (The cleanliness level should be, if possible, class 1 000 at least.) 12 PRECAUTIONS FOR BUILT-IN LENS CCD AREA SENSORS ø Make sure there is no dust or contamination on the lens and screw it on the lens holder. ø Dust from static electricity should be blown off with an ionized air blower. For antielectrostatic measures, however, ground all the leads on the device before blowing off the dust. ø The contamination on the surface of the lens should be wiped off with a clean applicator soaked in isopropyl alcohol. Wipe slowly and gently in one direction only. – Frequently replace the applicator and do not use the same applicator to clean more than one device. THE SHAPE OF THE TEMPERATURE OF THE IRON END THE IRON END 4. Other 1) Soldering should be manually performed under the following conditions : ø Use ESD-measured soldering iron ø The conditions of the soldering time in which the soldering iron touches the package, differs by the shape and the temperature of the iron end. Refer to the table below and take great care in soldering. SOLDERING TIME Ø3.2 R0.5 0.5 6.5 17 (Unit : mm) 17 (Unit : mm) Below 350 ˚C Time touching the package should be less than 40 seconds Below 300 ˚C Below 275 ˚C Time touching the package should be less than 25 seconds Time touching the package should be less than 35 seconds 2) There is no guarantee of the performance of the device which has been removed or resoldered after being soldered once under the conditions mentioned above. – In case there seems to be an inferior device, consult with our sales office before removing it. 3) Avoid using or storing the CCD at high temperature or high humidity as it is a precise optical component. Do not give a mechanical shock to the CCD. 4) Do not expose the device to strong light. For the color device, long exposure to strong light will fade the color of the color filters. – In case where the soldering may exceed the time mentioned above, resume the work after the device returns to normal temperature. ø Do not put too much force onto the lens and the lens holder while soldering. ø Be careful not to let the soldering iron touch the lens holder. – Soldering can be quickly/neatly done by laying the soldering iron so it lightly touches the border between the package and the circuit board and sliding it in sideways. 13
