? 20 ? ICX285AL 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) soldering a) make sure the package temperature does not exceed 80 c. b) solder dipping in a mounting furnace causes damage to the glass and other defects. use a ground 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, use a thermal controller of the zero cross on/off type and connect it to ground. 3) dust and dirt protection image sensors are packed and delivered by taking care of protecting its glass plates from harmful dust and dirt. clean glass plates with the following operation as required, and use them. a) perform all assembly operations in a clean room (class 1000 or less). 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. e) when a protective tape is applied before shipping, just before use remove the tape applied for electrostatic protection. do not reuse the tape. 4) do not expose to strong light (sun rays) for long periods. for continuous using under cruel condition exceeding the normal using condition, consult our company. 5) exposure to high temperature 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 too much mechanical shocks.
