4-3. REPLACEMENT OF CCD SENSOR
4-3-1. BEFORE REPLACEMENT
1) The CCD image sensor is more sensitive to electrostatic breakage than C-MOS LSI. Therefore sufficient means to prevent electrostatic damage must be taken when it is replaced. � Ground the soldering iron. � Ground also the human body, using the wrist strap(through an 1 Mohm resistor). � Until the CCDsensor is mounted on the PWB, fit it to the conductive sponge, and short-circuit the foot lead. 2) Take utmost care so that the surface glass of CCD sensor and optical filter are not contaminated and damaged. If any contamination is found, for example fingerprint, wipe it off with silicon paper or clean chamois skin. 3) When replacing the CCD sensor, use the antistaic grounded soldring iron, and perform quickly soldering.
