?13 ILX505A notes on handling 1) static charge prevention ccd image sensors are easily damaged by static discharge. before handling be sure to take the following protective measures. a) either handle bare handed or use non chargeable gloves, clothes or material. also use conductive shoes. b) when handling directly use an earth band. c) install a conductive mat on the floor or working table to prevent the generation of static electricity. d) ionized air is recommended for discharge when handling ccd image sensor. e) for the shipment of mounted substrates, use boxes treated for the prevention of static charges. 2) regulation for raising and lowering the power supply voltage when raising the supply voltage, first raise v dd1 (9v) and then v dd2 (5v). similarly, lower v dd2 (5v) first and then v dd1 (9v). 3) soldering a) make sure the package temperature does not exceed 80?. b) 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. c) to dismount an image sensor, do not use a solder suction equipment. when using an electric desoldering tool, ground the controller. for the control system, use a zero cross type. 4) dust and dirt protection a) operate in clean environments. b) do not either touch glass plates by hand or have any object come in contact with glass surfaces. should dirt stick to a glass surface, blow it off with an air blower. (for dirt stuck through static electricity ionized air is recommended.) c) clean with a cotton bud and ethyl alcohol if the grease stained. be careful not to scratch the glass. d) keep in a case to protect from dust and dirt. to prevent dew condensation, preheat or precool when moving to a room with great temperature differences. 5) exposure to high temperatures or humidity will affect the characteristics. accordingly avoid storage or usage in such conditions. 6) ccd image sensors are precise optical equipment that should not be subject to mechanical shocks.
