21 a i 339 a1 pros co., ltd. professional promotion process profit this section provides notes on ha ndling ccd image sensors as optic al devices implemented as a mos integrated circuit ( ic ). 1) cautions to static electricity you should take extreme care to static electricity. as a rule, device handling should be done in epa ( epa : esd protection area (esd : electrostatic discharge ) ). if the static electricity discha rges to the ccd?s pins, transfer efficiency may be reduced and other characteristics changed dependi ng on the voltage if the esd. in extreme cases, the protection circuits may break down and the device became inoperable. (1) in dry air, since a possibility t hat static electricity will occur by friction becomes high, please perform moisture control of the working space to more than 50 % rh (2) use of dischargers, such as ionized air, can be effective in prompting the discharge of static electricity (3) since static charge of several thousand volt s can accumulate due to friction between the human body and synthetic fiber clothing, staff should always wear work clothes and uniforms made from antistatic materials. also, staff should wear conductive footwear. (4) when handling ccd?s, staff should use antistatic gloves and grounded, their bodies by wearing wrist strap connected to ground through 1m resistance. also, prevent static charges from accumulating by spreading grounded conductive sheets on the floors and workbenches where ccds will be handled. (5) please take extreme care to static electricity in your assemble process line involving products storaging. 2) notes on power supply application although there is a list of points that require care and attention with respect to applying the power supply levels provided separately in the ? note on power supply application? document, the conditions listed below must also be met (1) do not use this device with any of the maximum ratings stipulated in the device standard exceeded. (2) do not apply power with the ccd pins connected incorrectly. that could result in source/drain reversals or the protection transistors being fo rward biased and large currents could destroy the inter connects on the chip. (3) do not use a power supply whose transient voltage levels exceed the maximum rating. (4) use the ?recommended sample circuit ( latch ? up prevention peripheral circuit example )? to prevent latch ? up from occurring. if latch ? up does occur, abnormal currents may flow between power supply terminal and gnd. the heat gen erated may make the ccd inoperative 3) notes on temperature in assembly process and soldering ccd has the limit temperature as follows, based on the physical limit of materials used. please take care not to hearten over this temperature in your process. 7. notes on device handling item limit temperature possible damage ( due to higher temperature than the limit ) ccd part 170 degradation of on-chip filter and lens
22 a i 339 a1 pros co., ltd. professional promotion process profit 4) notes on ccds as optical elements (1) this ccd features micro lenses that increase the ability of the photodiodes to collect light and color filter that allow the ccd to recognize color informat ion integrated on the chip itself in the sections of the ccd that perform t he photoelectrical conversion. since these on-chip components ate implemented us ing plastics, the transpar ency of the filter and lens materials is reduced by the light that ent ers the ccd depending on the spectral characteristics, intensity, and exposure time. due to this fact, these devices must be protect ed from uv light, sunlight, and any other bright light during all phases of use and handling, includi ng storage, transport and end product manufacture. (2) if the same pattern is protected onto the ccd image sensor for an extended period, depending on the intensity of the image and the ti me, that pattern may be burned onto the sensor resulting in the pattern being reflected in the characteristic or va riations in characteristic , regardless of whether of not power is applied. when not using a ccd, we recommend blocking all light and turning off the power. 5) storage environment ccd is a precision optical product. therefore, temperature, humidity, radiation and static electricity etc. of storage environment have to be controlled. please pay attention to the following when storing ccd. (1) storage condition of ccd a) packed condition. please storage ccd as it packed on our deliv ery packing in the following environment. temperature : ta = 25 10 humidity : rh = 60 % or less storage life : 1year b) opened pack condition when you opened pack, please keep environment as follows. temperature : ta = 23 5 humidity : rh = 10 % or less storage life : 3 months if you can not store ccd in dry air, please keep environment as follows. temperature : ta = 23 5 humidity : rh = 30 ~ 60 % storage life : 3 months but, the condition should fulfill the following equation. rh < -3x ts + 114 ( red area in fig.1 )
23 a i 339 a1 pros co., ltd. professional promotion process profit (2) other cautions a) do not store ccd in a location where they will be irradiated sunlight, uv and so on. b) do not subject these devices to rapid chang e in temperature that could cause condensation. c) do not subject these devices to ionizing radiat ion, electrostatic fields or discharge, or strong magnetic fields. d) if the storage location is humidified with a humidifier in the winter, use water that ha been brought to a boil. this is because chlorine and other chemicals dissolv ed in the water could cause oxidation of the leads. e) store packing containers in a place where they will not be subject to variation, mechanical shock, or being stacked under other materials or freight. 6)dust and contamination dust or contamination on the glass surface could dete riorate the output characterist ic or cause a scar. in order to minimize dust or contamination on the glass surface, take the following precautions : (1) handle ccd in a clean environment such as a cleaned booth. perform all lens assembly and work in a clean room. (2) do not touch the glass surface with the finger. if dust or contamination gets on the glass surface, the following cleaning method is recommended: ? dust from static electricity should be blown off with an ionized air blower. for anti electrostatic measure, however, ground all the leads on device before blowing off the dust. ? the contamination on the glass surface should be wiped of with a clean applicator socked in isopropyl alcohol. wipe slowly and gently in one directly only. frequently replace the applicator and do not us e the same applicator to clean more than one device
