14.10.3 Note prior to use
Note:
Please clean them to remove flux from them using the dipping, boiling, and vapor methods in isopropyl alcohol
for up to 5 minutes.
Please inform us if you are to use aqueous or semi-aqueous cleaning or another methods.
Do not use ultrasonic cleaning because semiconductor device on the products, bonding wires may be broken
by resonance.
After cleaning, please dry the products thoroughly. If you touch the products that have not been dried enough
yet, you need to take care because the marking of the products may get thin or blurred.
Do not measure electrical characteristics, until the products get dried enough.
If you use no-cleaning type flux and you don’t clean our products, you must confirm the reliability of the
products fully in advance.
You should storage this product under MSL2 at the recommendable condition of soldering, which is described
at 13.2. So this product can be stored without baking a half year at below 30℃ 60%R.H.
In case you store them over the limit, please bake this product before soldering.
If these are unpacked condition, please bake them at 125℃±5℃/24hour. If these are packed in a tape, please
bake them before soldering at 60℃±5℃/168hour.
Avoid damp heated places or such places where there are large temperature changes, because water may
condense on the products, the characteristics may be reduced in quality, and/or be degraded in the
solderability.
If you store the products for a long time (more than 1 year), the products may be degraded in solderability and
may be rusty. Please confirm solderability for the products regularly.
breeze, in an atmosphere containing corrosive gas (Cl2,NH3,SO2,NOX and so on).
The products are not waterproof, chemical-proof or rust-proof.
In order to prevent leakage of electricity and abnormal temperature increase of the products, do not use the
products under the following circumstances:
Please use the products within specified values (power supply, temperature, input, output and load condition,
and so on). Input voltage drop for line impedance, so please make sure that input voltage is included in
specified values.
If you use the products over the specified values, it may break the products, reduce the quality, and even if the
products can endure the condition for short time, it may cause degradation of the reliability.
Also please take care that the external voltage over output voltage of DC-DC Converter does not applies to
output of this DC-DC Converter.
If you apply high static electricity, over rated voltage or reverse voltage to the products, it may cause defects in
the products or degrade the reliability.
Please avoid the following items:
Do not give an excessive mechanical shock..
If you drop the products on the floor, etc., it may occur a crack to the core of inductors and monolithic ceramic
capacitors.
Do not give a strong shock such as a drop in handling.
(1) in an atmosphere containing corrosive gas (Cl2, NH3, SO2, NOX and so on).
(2) in a dusty place.
(3) in a place exposed to direct sunlight.
(4) in such a place where water splashes or in such a humid place where water condenses.
(5) in a place exposed to sea breeze.
(6) in any other places similar to the above (1)through (5).
(1) over rating power supply, reverse power supply or not-enough connection of 0 V(DC) line.
(2) electrostatic discharge by production line and/or operator.
(3) electrified product by electrostatic induction.
