NOTES FOR USING SMD TYPE CONNECTORS (Common)
6) The temperatures are measured at the
surface of the PC board near the
connector terminals. (The setting for the
sensor will differ depending on the sensor
used, so be sure to carefully read the
instructions that comes with it.)
7) The temperature profiles given in this
catalog are values measured when using
the connector on a resin-based PC
board. When performed reflow soldering
on a metal board (iron, aluminum, etc.) or
a metal table to mount on a FPC, make
sure there is no deformation or
discoloration of the connector beforehand
and then begin mounting.
2. Hand soldering
1) Set the soldering iron so that the tip
temperature is less than that given in the
table below.
Table A
2) Do not allow flux to spread onto the
connector leads or PC board. This may
lead to flux rising up to the connector
inside.
Handling Single
Components
1) Make sure not to drop or allow parts to
fall from work bench
2) Excessive force applied to the
terminals could cause them to warp,
come out, or weaken the adhesive
strength of the solder. Handle with care.
3) Repeated bending of the terminals
may break them.
4) Do not use alcohol for cleaning. Doing
so may whiten the surface of molded
parts.
Storage of connectors
1) To prevent trouble from voids or air
pockets by heat of reflow soldering, avoid
storing the connectors in areas of high
humidity. When storing the connectors for
more than six months, be sure to store
them in a storage area where the
humidity is properly controlled.
2) Depending on the connector type, the
color of the connector may vary from
connector to connector if produced at

3) Touch the soldering iron to the foot
pattern. After the foot pattern and
connector terminal are heated, apply the
solder wire so it melts at the end of the
connector terminals.
4) Be aware that soldering while applying
a load on the connector terminals may
cause improper operation of the
connector.
5) Thoroughly clean the soldering iron.
6) Flux from the solder wire may get on
the contact surfaces during soldering
operations. After soldering, carefully
check the contact surfaces and clean off
any solder before use.
7) For soldering of prototype devices
during product development, you can
perform soldering at the necessary
locations by heating with a hot-air gun by
applying cream solder to the foot pattern
Cleaning flux from PC board
1) To increase the cleanliness of the
cleaning fluid and cleaning operations,
prepare equipment for a cleaning
process that begins with boil cleaning,
ultrasonic cleaning, and then to vapor
cleaning.
2) Carefully oversee the cleanliness of
the cleaning fluids to make sure that the
contact surfaces do not become dirty
from the cleaning fluid itself.
3) Since some powerful cleaning may
dissolve molded components of the
connector and wipe off printed letters, we
recommend aqua pura electronic parts
cleaners. Consult us if you wish other
types of cleaning fluids.
4) Please note that the surfaces of
molded parts may whiten when cleaned
with alcohol.
different times, and some connectors
more even change color slightly if
subjected to ultraviolet rays during
storage. This is normal and will not affect
the operation of the connector.
3) When storing the connectors with the
PC boards assembled and components
alreeady set, be careful not to stack them
up so the connectors are subjected to
excessive forces.

beforehand. However, at this time, make
sure that the air pressure does not move
connectors by carefully holding them
down with tweezers or other similar tool.
Also, be careful not to go too close to the
connectors and melt any of the molded
components.
8) When soldering the shell terminals of,
for example, I/O connectors, avoid
applying an excessive amount of solder,
or it may flow into the shell.
3. Solder reworking
1) Finish reworking in one operation.
2) For reworking of the solder bridge, use
a soldering iron with a flat tip. To prevent
flux from climbing up to the contact
surfaces, do not add more flux.
3) Keep the soldering iron tip temperature
below the temperature given in Table A.
4) When soldering the shell terminals of,
for example, I/O connectors, avoid
applying an excessive amount of solder,
or it may flow into the shell.
Handling the PC board
• Handling the PC board after
mounting the connector
When cutting or bending the PC board
after mounting the connector, be careful
that the soldered sections are subjected
to excessive forces.
4) Avoid storing the connectors in
locations with excessive dust. The dust
may accumulate and cause improper
connections at the contact surfaces.
