VE-CG30U VE-CG40U 4-2. REPLACEMENT OF CCD SENSOR 4-2-1. 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 M ohm resistor). • Until the CCD sensor is mounted on the PWB, fit it to the conductive sponge, and short-circuit the foot lead.
