NOTES FOR USING SMD TYPE CONNECTORS (Common)
Regarding the design of devices and PC board patterns
Regarding the selection of the connector placement machine and the mounting
procedures
NOTES FOR USING SMD TYPE CONNECTORS
(Common)
1) When connecting several connectors
together by stacking, make sure to
maintain proper accuracy in the design of
structure and mounting equipment so
that the connectors are not subjected to
twisting and torsional forces.
2) With mounting equipment, there may
be up to a ±0.2 to 0.3-mm error in
positioning. Be sure to design PC boards
and patterns while taking into
consideration the performance and
abilities of the required equipment.
3) Some connectors have tabs embossed
on the body to aid in positioning. When
using these connectors, make sure that
the PC board is designed with positioning
holes to match these tabs.
4) To ensure the required mechanical
strength when soldering the connector
terminals, make sure the PC board
meets recommended PC board pattern
design dimensions given.
5) For all connectors of the narrow-pitch
series, to prevent the PC board from
coming off during vibrations or impacts,
and to prevent loads from falling directly
on the soldered portions, be sure to
design some means to fix the PC board
in place.
Example) Secure in place with screws
When connecting PC boards, take
appropriate measures to prevent the
connector from coming off.
6) Notes when using a FPC.
(1) When the connector is soldered to an
FPC board, during its insertion and
removal procedures, forces may be
applied to the terminals and cause the
soldering to come off. It is recommended
to use a reinforcement board on the
backside of the FPC board to which the
connector is being connected. Please
make the reinforcement board
dimensions bigger than the outer limits of
the recommended PC board pattern
(should be approximately 1 mm greater
than the outer limit).
Material should be glass epoxy or
polyimide, and the thickness should be
between 0.2 and 0.3 mm.
(2) Collisions, impacts, or turning of FPC
boards, may apply forces on the
connector and cause it to come loose.
Therefore, make to design retaining
plates or screws that will fix the connector
in place.
7) The narrow-pitch connector series is
designed to be compact and thin.
Although ease of handling has been
taken into account, take care when
mating the connectors, as displacement
or angled mating could damage or
deform the connector.

1) Select the placement machine taking
into consideration the connector height,
required positioning accuracy, and
packaging conditions.
2) Be aware that if the catching force of
the placement machine is too great, it
may deform the shape of the connector
body or connector terminals.
3) Be aware that during mounting,
external forces may be applied to the
connector contact surfaces and terminals
and cause deformations.
4) Depending on the size of the
connector being used, self alignment
may not be possible. In such cases, be
sure to carefully position the terminal with
the PC board pattern.
5) The positioning bosses give an
approximate alignment for positioning on
the PC board. For accurate positioning of
the connector when mounting it to the PC
board, we recommend using an
automatic positioning machine.

NOTES FOR USING SMD TYPE CONNECTORS (Common)
Regarding soldering
1. Reflow soldering
1) Measure the recommended profile
temperature for reflow soldering by
placing a sensor on the PC board near
the connector surface or 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.)
2) As for cream solder printing, screen
printing is recommended.
3) See the specifications and drawings
for the product in question for the metal
mask pattern diagrams.
4) When mounting on both sides of the
PC board and the connector is mounting
on the underside, use adhesives or other
means to ensure the connector is
properly fixed to the PC board. (Double
reflow soldering on the same side is
possible.)
5) N
2 reflow, conducting reflow soldering
in a nitrogen atmosphere, increases the
solder flow too greatly, enabling wicking
to occur. Make sure that the solder feed
rate and temperature profile are
appropriate.
Soldering conditions
Please use the reflow temperature profile
conditions recommended below for
reflow soldering. Please contact us
before using a temperature profile other
than that described below (e.g. lead-free
solder).
• Narrow-pitch connectors
(except P5 floating and P8 type)
• Narrow-pitch connector (P5 floating, P8)
For products other than the ones above,
please refer to the latest product
specifications.
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.
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
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.
Example:
Inflidge Industrial, Ltd.
Super Air Heater
Digital temperature controller
Air heater with internal temperature
sensor
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.

Other Notes
Regarding sample orders to confirm proper mounting
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.
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.
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.
Do not the soldered areas to be subjected to forces
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
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.
4) Avoid storing the connectors in
locations with excessive dust. The dust
may accumulate and cause improper
connections at the contact surfaces.
1) These products are made for the
design of compact and lightweight
devices and therefore the thickness of the
molded components has been made very
thin. Therefore, be careful during
insertion and removal operations for
excessive forces applied may damage
the products.
2) Dropping of the products or rugged
mishandling may bend or damage the
terminals and even hinder proper reflow
soldering.
3) Before soldering, try not to insert or
remove the connector more than
absolutely necessary.
4) When coating the PC board after
soldering the connector to prevent the
deterioration of insulation, perform the
coating in such a way so that the coating
does not get on the connector.
5) There may be variations in the colors
of products from different production lots.
This is normal.
6) The connectors are not meant to be
used for switching.
7) Be sure not to allow external pressure
to act on connectors when assembling
PCBs or moving in block assemblies.
When ordering samples to confirm
proper mounting with the placement
machine, connectors are delivered in 50-
piece units in the condition given right.
Consult a sale representative for ordering
sample units.
