Safety Precautions

Precautions for Correct Use
RF MEMS Switch Handling
•
Use the RF MEMS Switch as soon as possible after opening the
moisture-proof package (within one week). If the RF MEMS Switch
is left for a long time after opening the moisture-proof package, the
appearance may suffer and seal failure may occur after the solder
mounting process. To store the RF MEMS Switch after opening the
moisture-proof package, place it into the original package and seal
the package with adhesive tape.
•
When washing the product after soldering the RF MEMS Switch to
a print circuit board, use a water-based solvent or alcohol-based
solvent and keep the solvent temperature to less than 40°C. Do not
put the RF MEMS Switch in a cold cleaning bath immediately after
soldering.
•
Do not use an Ultrasonic wash.
•
This RF MEMS Switch is easily damaged by static electricity. When
handling the RF MEMS Switch, take countermeasure against static
electricity (100 V or less). Contact OMRON for additional guide-
lines.
•
When handling the RF MEMS Switch, do not drop.
•
Do not apply force resulting in the product to transform and change
in quality.
•
Turn off power when doing the exchange and the wiring work of the
RF MEMS Switch.
•
Do not touch the terminal of the RF MEMS Switch when energized.
Long-term, Continuous ON Contacts
•
Using the RF MEMS Switch in a circuit where the RF MEMS Switch
will be ON continuously for long periods (more than 24 hours)
(rather than switching) can lead to unstable contacts. If a single-
side stable model must be used in this kind of circuit, we recom-
mend adding fail-safe circuits in case the contact fails.
Claw Securing Force During Automatic
Mounting
•
During automatic insertion of RF MEMS Switches, be sure to set
the securing force of each claw to the following so that the RF
MEMS Switch's characteristics will be maintained.
Direction C: 2.0 N max.
Environmental Conditions for Usage,
Storage, and Transport
•
Avoid direct sunlight when using, storing, or transporting the RF
MEMS Switch and maintain normal temperature, humidity, and
pressure conditions.
•
Avoid caustic gases when using, storing, or transporting the RF
MEMS Switch.
Coating
•
Do not coat the RF MEMS Switch when it is mounted to the print
circuit board. Do not wash the print circuit board after the RF
MEMS Switch is mounted using detergent containing silicone. Oth-
erwise, the detergent may remain on the surface of the RF MEMS
Switch.
