ILX6A Notes of Handling ) Static charge prevention CCD image seors 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) Itall 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 seor. e) For the shipment of mounted substrates, use boxes treated for prevention of static charges. ) Notes on Handling CCD Cer-DIP Packages The following points should be observed when handling and italling cer-dip packages. a) Remain within the following limits when applying static load to the ceramic portion of the package: () Compressive strength: 39N/surface (Do not apply load more than.7mm iide the outer perimeter of the glass portion.) () Shearing strength: 9N/surface (3) Teile strength: 9N/surface (4) Torsional strength:.9nm Upper ceramic layer Lower ceramic layer 39N () Low-melting glass 9N 9N.9Nm () (3) (4) b) In addition, if a load is applied to the entire surface by a hard component, bending stress may be generated and the package may fracture, etc., depending on the flatness of the ceramic portion. Therefore, for itallation, either use an elastic load, such as a spring plate, or an adhesive. c) Be aware that any of the following can cause the glass to crack: because the upper and lower ceramic layers are shielded by low-melting glass, () Applying repetitive bending stress to the external leads. () Applying heat to the external leads for an extended period of time with soldering iron. (3) Rapid cooling or heating. (4) Applying a load or impact to a limited portion of the low-melting glass with a small-tipped tool such as tweezers. () Prying the upper or lower ceramic layers away at a support point of the low-melting glass. Note that the preceding notes should also be observed when removing a component from a board after it has already been soldered. 3) Soldering a) Make sure the package temperature does not exceed 8 C. b) Solder dipping in a mounting furnace causes damage to the glass and other defects. Use a grounded 3W soldering iron and solder each pin in less then seconds. For repairs and remount, cool sufficiently. c) To dismount an imaging device, 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.
ILX6A 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 glass surface is grease stained. Be careful not to scratch the glass. d) Keep in a case to protect from dust and dirt. To prevent dew condeation, preheat or precool when moving to a room with great temperature differences. ) Exposure to high temperatures or humidity will affect the characteristics. Accordingly avoid storage or usage in such conditio. 6) CCD image seors are precise optical equipment that should not be subject to mechanical shocks. 7) Normal output signal is not obtained immediately after device switch on.
