1/4 INCH CCD IMAGE SENSOR FOR NTSC CAMERA S5F425NX03 Next, the signals through H-CCD at line A2 are [Mg+Cy], [G+Ye], [Mg+Cy], [G+Ye]. Simmilary, Y and C signals are composed at line A2 as follows Accordingly, Y signal is balanced in relation to scanning lines, and C signal takes the form of R-Y and -(B-Y) on alternate lines. It is same for B field. TEST METHODS 1. Measure the light intensities (L) when the averaged illuminance output value (Y) is the standard illuminance output value, 150mV (Y A ) and when half of 150mV (1/2 Y A ). 2. Adjust the light intensity to 15 times of the value with which Y is Y A , then measure the averaged illuminance output value (Y = Y SAT ). 3. Adjust the light intensity to 500 times of the value with which Y is Y A , then remove the read-out clock and drain the signal in photosensors by the electronic shutter operation in all the respective horizontal blanking times with the other clocks unchanged. Measure the maximum illuminance output value (Y SM ). 4. Adjust the light intensity to 1,000 times of the value with which Y is Y A , then inspect whether there is blooming phenomenon or not.

S5F425NX03 1/4 INCH CCD IMAGE SENSOR FOR NTSC CAMERA HANDLING INSTRUCTIONS
- Static Charge Prevention CCD image sensors can be easily damaged by static discharge. Before handling, be sure to take the following protective measures. — Use non chargeable gloves, clothes or material. Also use conductive shoes. — When handling directly, use an earth band. — Install a conductive mat on the floor or working table to prevent generation of static electricity. — Ionized air is recommended for discharging when handling CCD image sensor. — For the shipment of mounted substrates, use boxes treated for the prevention of static charges.
- Soldering — Make sure the package temperature does not exceed 80 °C. — Solder dipping in a mounting furnace causes damage to the glass and other defects. Use a grounded 30W soldering iron and solder each pin in less than 2 seconds. For repairs and remount, cool sufficiently. — To dismount an imaging device, do not use a solder suction equipment. When using an electronic disoldering tool, use a thermal controller of the zero cross on/off type and connect to ground.
- Dust and Dirt Protection — Operate in the clean environments (around class 1000 will be appropriate). — Do not either touch glass plates by hand or have object come in contact with glass surface. Should dirt stick to a glass surface blow it off with an air blow (for dirt stuck through static electricity ionized air is recommended). — Clean with a cotton bud and ethyl alcohol if the glass surface is grease stained. Be careful not to scratch the glass. — Keep in case to protect from dust and dirt. To prevent dew condensation, preheat or precool when moving to a room with great temperature differences. — When a protective tape is applied before shipping, just before use remove the tape applied electrostatic protection. Do not reuse the tape.
- Do not expose to strong light (sun rays) for long period, color filter are discolored.
- Exposure to high temperature or humidity will affect the characteristics. accordingly avoid storage or usage in such conditions.
- CCD image sensors are precise optical equipment that should not be subject to mechanical shocks.
