Notes Handling
Static charge prevention image sensors easily damaged static discharge. Before handling sure take following protective measures. Either handle bare handed non-chargeable gloves, clothes material. Also conductive shoes. When handling directly earth band. Install conductive floor working table prevent generation static electricity. Ionized recommended discharge when handling image sensor. shipment mounted substrates, boxes treated prevention static charges.
Soldering Make sure package temperature does exceed Solder dipping mounting furnace causes damage glass other defects. ground soldering iron solder each less than seconds. repairs remount, cool sufficiently. dismount image sensor, solder suction equipment. When using electric desoldering tool, thermal controller zero cross On/Off type connect ground.
Dust Dirt protection Perform assembly operations clean room (class 1000 less). either touch glass plates hand have object come contact with glass surfaces. Should dirt stick glass surface, blow with blower. (For dirt stuck through static electricity ionized recommended.) Clean with cotton ethyl alcohol grease stained. careful scratch glass. Keep case protect from dust dirt. prevent condensation, preheat precool when moving room with great temperature differences.
Others expose strong light (sun rays) long periods. Exposure high temperature humidity will affect characteristics. Accordingly avoid storage usage such conditions.
