NOTICE
1.
Storage
Please store the products in room where temperature /
humidity is stable. Conditions should be:
Temperature
: 5 to 35°C
Humidity
: 30 to 60% RH
If products are stored for more than a year, solderability
may be degraded. Please confirm it regularly.
2.
Transportation
If you transport the products, please pack them so that
the package will not be damaged by mechanical
vibration / shock and please educate and guide a carrier
to prevent rough handling.

RoHS SMD PRODUCTS SOLDERING GUIDELINES
1. WASHING CONDITIONS
Our non hermetic SMD products are strictly non-washable as liquid cleaning solutions could penetrate the base to cap seal.
No-washing type flux with no washing is highly recommended. Please consult factory for any other process.

Additional recommendations:
•
•
•
•
do not vibrate during reflow soldering
do not reflow solder on back side
Only one reflow is allowed
solder adhesion may vary depending on the motherboard’s thermal capacity and other factors
Hand soldering (not recommended):
Maximum temperature: 300°C/5 sec, fine tipped soldering iron
