HANDLING INSTRUCTIONS
Static Charge Prevention image sensors easily damaged static discharge. Before handling, sure take following protective measures. chargeable gloves, clothes material. Also conductive shoes. When handling directly, earth band. Install conductive floor working table prevent generation static electricity. Ionized recommended discharging 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. grounded soldering iron solder each less than seconds. repairs remount, cool sufficiently. dismount imaging device, solder suction equipment. When using electronic disoldering tool, thermal controller zero cross on/off type connect ground.
Dust Dirt Protection Operate clean environments (around class 1000 will appropriate). either touch glass plates hand have object come contact with glass surface. Should dirt stick glass surface blow with blow(for dirt stuck through static electricity ionized recommended). Clean with cotton ethyl alcohol glass surface grease stained. caerful scratch glass. Keep case protect from dust dirt. prevent condensation, preheat precool when moving room with great temperature differences. When protective tape applied before shipping, just before remove tape applied electrostatic protection. reuse tape.
expose strong light (sun rays) long period, color filter discolored
Exposure high temperature humidity will affect characteristics. accordingly avoid storage usage such conditions.
image sensors precise optical equipment that should subject mechanical shocks.
