NOTES
1. Mounting
Use lands on the printed-circuit boards to
which the sensor can be securely xed.
2. Soldering
Due to its small size, the thermal capacity
of the pressure sensor DIP type is low.
Therefore, take steps to minimize the
effects of external heat.
Damage and changes to characteristics
may occur due to heat deformation.
Use a non-corrosive resin type of ux.
Since the pressure sensor DIP type is
exposed to the atmosphere, do not allow
ux to enter inside.
1) Manual soldering
Set the soldering tip from 260 to 300
°C
500 to 572
°F (30W), and solder for no
more than 5 seconds.
Please note that output may change if
the pressure is applied on the terminals
when the soldering.
Thoroughly clean the soldering iron.
2) DIP soldering (DIP terminal type)
Please keep the DIP solder bath
temperature no higher than 260
°C 500°F.
When soldering, heat should be applied
no longer than ve seconds.
When mounting onto a PCB of low
thermal capacity, please avoid DIP
soldering as this may cause heat
deformity.
3) Solder reworking
Finish reworking in one operation.
For reworking of the solder bridge, use
a soldering iron with a at tip. Please do
not add more ux when reworking.
Please use a soldering iron that is
below the temperature given in the
specications in order to maintain the
correct temperature at the tip of the
soldering iron.
4) Too much force on the terminals will
cause deformation and loss in
effectiveness of the solder. Therefore,
please avoid dropping and careless
handling of the product.
5) Please control warping of the PCB
within 0.05 mm of the sensor width.
6) When cut folding the PCB after
mounting the sensor, take measures to
prevent stress to the soldered parts.
7) The sensor terminals are designed to
be exposed, so contact of the terminals
with metal shards and the like will cause
output errors. Therefore, please be
careful and prevent things such as metal
shards and hands from contacting the
terminals.
8) To prevent degradation of the PCB
insulation after soldering, please be
careful not to get chemicals on the
sensor when coating.
9) Please consult us regarding the use of
lead-free solder.
3. Connections
1) Please perform connections correctly
in accordance with the terminal
connection diagram. In particular, be
careful not to reverse wire the power
supply as this will cause damage or
degrade to the product.
2) Do not connect terminals that are not
used. This can cause malfunction of the
sensor.
4. Cleaning
1) Since the pressure sensor chip is
exposed to the atmosphere, do not allow
cleaning uid to enter inside.
2) Avoid ultrasonic cleaning since this
may cause breaks or disconnections in
the wiring.
5. Environment
1) Please avoid using or storing the
pressure sensor chip in a place exposed
to corrosive gases (such as the gases
given off by organic solvents, sulfurous
acid gas, hydrogen suldes, etc.) which
will adversely affect the performance of
the pressure sensor chip.
2) To ensure resistance to power supply
superimposed noise, you must provide a
capacitor at the power supply input
terminal of the sensor in order to stabilize
the power supply voltage. We
recommend to provide 0.1 μF and 1,000
pF capacitor in parallel. Please conrm
the noise resistance with the actual
equipment and choose adequate
capacitor.
3) Since the internal circuitry may be
destroyed if an external surge voltages is
supplied, provide an element which will
absorb the surges.
4) Malfunctioning may occur if the
product is in the vicinity of electrical noise
such as that from static electricity,
lightning, a broadcasting station, an
amateur radio, or a mobile phone.
5) Since this pressure sensor chip does
not have a water-proof construction,
please do not use the sensor in a location
where it may be sprayed with water, etc.
6) Avoid using the pressure sensors chip
in an environment where condensation
may form.
Furthermore, its output may uctuate if
any moisture adhering to it freezes.
7) The pressure sensor chip is
constructed in such a way that its output
will uctuate when it is exposed to light.
Especially when pressure is to be applied
by means of a transparent tube, take
steps to prevent the pressure sensor chip
from being exposed to light.
8) Avoid using the pressure sensor chip
where it will be susceptible to ultrasonic
or other high-frequency vibration.
6. Quality check under actual loading
conditions
To assure reliability, check the sensor
under actual loading conditions. Avoid
any situation that may adversely affect its
performance.
7. Other handling precautions
1) That using the wrong pressure range
or mounting method may result in
accidents.
2) The only direct pressure medium you
can use is dry air. The use of other
media, in particular, corrosive gases
(organic solvent based gases, sulfurous
acid based gases, and hydrogen sulde
based gases, etc.) and media that
contains moisture or foreign substances
will cause malfunction and damage.
Please do not use them.
3) The pressure sensor chip is positioned
inside the pressure inlet. Never poke
wires or other foreign matter through the
pressure inlet since they may damage
the chip or block the inlet. Avoid use
when the atmospheric pressure inlet is
blocked.
4) Use an operating pressure which is
within the rated pressure range. Using a
pressure beyond this range may cause
damage.
5) Since static charge can damage the
pressure sensor chip, bear in mind the
following handling precautions.
When storing the pressure sensor
chips, use a conductive material to short
the pins or wrap the entire chip in
aluminum foil. Plastic containers should
not be used to store or transport the
chips since they readily become charged.
When using the pressure sensor chips,
all the charged articles on the bench
surface and the work personnel should
be grounded so that any ambient static
will be safely discharged.
6) Based on the pressure involved, give
due consideration to the securing of the
pressure sensor DIP type and to the
securing and selection of the inlet tube.
Consult us if you have any queries.
