Notes on Handling
1) Static charge prevention
2) Notes on handling CCD Cer-DIP package
3) Soldering
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
b) When handling directly use an eath band.
c) Install a conductive mat on the floor or working table to prevent the generation of static electricity.
d) lonized air is recommended for discharge when handling CCD image sensors.
e) For the shipment of mounted substrates use cartons treated for the prevention of static charges.
The following points should be observed when handling and installing Cer-DIP packages.
a) Remain within the following limits when applying static load to the ceramic portion of the package:
b) In addition, if a load is applied to the entire surface by a hard component, bending stress may be
c) Be aware that any of the following can cause the glass to crack because the upper and lower ceramic
a) Make sure the package temperature does not exceed 80°C.
b) Solder dipping in a mounting furnace causes demage to the glass abd other defects. Use a 30W
c) To dismount image sensors, do not use a solder suction equipment. When using an electric desoldering

Therefore, for installation, either use an elastic load, such as a spring plate, or an adhesive.

it has already been soldered.
