3. Head type
The electrical terminals of the head type are connected to the internal image sensor signal terminals. Take the
following precautions on static electricity management, circuit board design, and handling, etc.
3-1. Static electricity management
Electrostatic sensitive products come with an electrostatic warning label on the product packing. Handling of
the product requires taking precautions on the following points to avoid product damage and deterioration due
to static electricity.
【

Electrostatic warning label
(1) Workplace and facilities, etc.
●
Lay a conductive mat (750 k
to 1 G
) on the surface of the workbench and ground it.
●
Use conductive flooring material or lay a conductive mat on the workplace floor and ground it.
●
Ground all manufacturing equipment and inspection devices.
●
Keep moisture at approximately 50%. Low humidity tends to cause static electricity and high humidity is
prone to moisture absorption.
(2) Handling
●
Using an ionizer or similar item to eliminate electrical charges is recommended when handling the product.
●
Wear anti-static clothing and conductive shoes (100 k
to 100 M
).
●
Attach a wrist strap (having protective resistance of 750 k
to 35 M
Ω
) directly to the skin, and ground the
strap. If the wrist strap does not include protective resistance, there is a risk of electric shock hazard due to
electric leak. Also wear conductive finger sacks or gloves.
●
Tools such as tweezers used to handle the product may sometimes become electrically charged. Connect a
ground line as needed.
●
Use a soldering iron with an insulation resistance of 10 M
Ω
or higher. The soldering iron tip should be
grounded.
●
If the product is induction-charged and contacts with a metal, excessive current may flow due to electrostatic
discharge causing damage to the product. To prevent induction charging, keep objects (insulators such as
plastic and vinyl, PC display monitors and keyboards, etc. that may possibly be electrically charged) away
from the product. The product may be induction-charged even by just bringing such objects close to the
product. If keeping such objects near the product is unavoidable, then use an ionizer, etc. to remove
electrostatic charges from the objects that are apt to be electrostatically charged.
●
Friction on the product causes electrostatic charges. If such friction is unavoidable, then remove the
electrostatic charges using an ionizer, etc.
