Notes on Using Narrow pitch Connectors/High Current Connectors
About safety remarks
Observe the following safety remarks to prevent accidents
and injuries.
• Do not use these connectors beyond the specification
sheets. The usage outside of specified rated current,
dielectric strength, and environmental conditions and
so on may cause circuitry damage via abnormal heating,
smoke, and fire.
• In order to avoid accidents, your thorough specification
review is appreciated. Please contact our sales
representative if your usage is out of the specifications.
Otherwise, Panasonic Industry Co., Ltd. cannot guarantee
the quality and reliability.
• Panasonic Industry Co., Ltd. is consistently striving to
improve quality and reliability. However, the fact remains
that electrical components and devices generally cause
failures at a given statistical probability. Furthermore, their
durability varies with use environments or use conditions.
In this respect, please check for actual electrical
components and devices under actual conditions before
use. Continued usage in a state of degraded condition
may cause the deteriorated insulation, thus result in
abnormal heat, smoke or firing. Please carry out safety
design and periodic maintenance including redundancy
design, design for fire spread prevention, and design for
malfunction prevention so that no accidents resulting in
injury or death, fire accidents, or social damage will be
caused as a result of failure of the products or ending life
of the products.
Regarding the design of devices and PC board patterns
• When using board to board connectors, a pair of board
shaII NOT be connected with multiple connectors.
Otherwise, misaligned connector positions may cause
mating failure or product breakage. Panasonic Industry
Co., Ltd. does not guarantee the failures caused by using
the multiple connectors.
• 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.
• 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.
• To ensure the required mechanical strength when
soldering the connector terminals, make sure the PC
board meets recommended PC board pattern design
dimensions given.
• PC board
Control the thicknesses of the cover lay and adhesive to
prevent poor soldering. This connector has no standoff.
Therefore, minimize the thickness of the cover lay, etc. so
as to prevent the occurrence of poor soldering.
• 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 mounting connectors on a FPC
• When the connector soldered to FPC is mated or
unmated, solder detachment may occur by the force to
the terminals.
Connector handling is recommended in the condition
when the reinforcing plate is attached to the backside
of FPC where the connector is mounted. The external
dimension of the reinforcing plate is recommended
to be larger than the dimension of “ Recommended
PC board pattern ” ( extended dimension of one side
is approximately 0.5 to 1.0 mm ). The materials and
thickness of the reinforcing plate are glass epoxy or
polyimide ( thickness 0.2 to 0.3 mm ) or SUS ( thickness
0.1 to 0.2 mm ).
• As this connector has temporary locking structure, the
connector mating may be separated by the dropping
impact depend on the size, weight or bending force
of the FPC. Please consider the measures at usage to
prevent the mating separation.
• 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.

Notes on Using Narrow pitch Connectors/High Current Connectors
Regarding the selection of the connector placement machine and the mounting procedures
• Select the placement machine taking into consideration
the connector height, required positioning accuracy, and
packaging conditions.
• Be aware that if the chucking force of the placement
machine is too great, it may deform the shape of the
connector body or connector terminals.
• Be aware that during mounting, external forces may be
applied to the connector contact surfaces and terminals
and cause deformations.
• 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.
• 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.
• In case of dry condition, please note the occurrence of
static electricity. The product may be adhered to the
embossed carrier tape or the cover tape in dry condition.
Recommended humidity is from 40 to 60% RH and please
remove static electricity by ionizer in manufacturing
process.
Regarding soldering
■ Reflow soldering
• Measure the recommended profile temperature for
reflow soldering by placing a sensor on the PC board
near the connector surface or terminals. ( Please refer
to the specification for detail because the temperature
setting differs by products. )
• As for cream solder printing, screen printing is
recommended.
• When setting the screen opening area and PC board
foot pattern area, refer the recommended PC board
pattern and window size of metal mask on the
specification sheet, and make sure that the size of
board pattern and metal mask at the base of the
terminals are not increased.
• Please pay attentions not to provide too much solder. It
makes miss mating because of interference at soldering
portion when mating.
Terminal
Paste solder
PC board foot pattern
• 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. )
• The condition of solder or flux rise and wettability varies
depending on the type of solder and flux. Solder and
flux characteristics should be taken into consideration
and also set the reflow temperature and oxygen level.

Notes on Using Narrow pitch Connectors/High Current Connectors
■ Hand soldering
• Be aware that soldering while applying a load on the
connector terminals may cause improper operation of
the connector.
• Thoroughly clean the soldering iron.
• 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.
• These connector is low profile type. If too much solder
is supplied for hand soldering, It makes miss mating
because of interference at soldering portion. Please pay
attentions.
• Set the soldering iron so that the tip temperature is less
than that given in the table below.

■ Solder reworking
• Finish reworking in one operation.
• In case of soldering rework of bridges. Do not use
supplementary solder flux. Doing so may cause contact
problems by flux.
• Keep the soldering iron tip temperature below the
temperature given in Table A.
Handling single components
• Make sure not to drop or allow parts to fall from work
bench.
• Excessive force applied to the terminals could cause
warping, come out, or weaken the adhesive strength of
the solder. Handle with care.
• Do not insert or remove the connector when it is not
soldered. Forcibly applied external pressure on the
terminals can weaken the adherence of the terminals
to the molded part or cause the terminals to lose their
evenness.
Precautions for mating
This product is designed with ease of handling. However,
in order to prevent the deformation or damage of contacts
and molding, take care and do not mate the connectors as
shown right.
Our products are symmetrical structure. Please avoid reverse
insertion of connector. Inserting a connector in a circuit
direction opposite to that you intended may cause circuitry
damage via abnormal heating, smoke, and fire.

Notes on Using Narrow pitch Connectors/High Current Connectors
Handling the PC board
■ Handling the PC board after mounting the
connector
The soldered areas should not be subjected to force.
When cutting or bending the PC board after mounting
the connector, be careful that the soldered sections are
subjected to excessive force.
Storage of connectors
• To prevent problems from voids or air pockets due to
heat of reflow soldering, avoid storing the connectors in
areas of high humidity.
• Depending on the connector type, the color of the
connector may vary from connector to connector
depending on when it is produced. Some connectors may
change color slightly if subjected to ultraviolet rays during
storage. This is normal and will not affect the operation
of the connector.
• When storing the connectors with the PC boards
assembled and components already set, be careful not
to stack them up so the connectors are subjected to
excessive forces.
• Avoid storing the connectors in locations with excessive
dust. The dust may accumulate and cause improper
connections at the contact surfaces.
Other Notes
• Do not remove or insert the electrified connector ( in the
state of carrying current or applying voltage ).
• Dropping of the products or rough mishandling may
bend or damage the terminals and possibly hinder proper
reflow soldering.
• Before soldering, try not to insert or remove the
connector more than absolutely necessary.
• 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.
• There may be variations in the colors of products from
different production lots. This is normal.
• The connectors are not meant to be used for switching.
• Product failures due to condensation are not covered by
warranty.
Regarding sample orders to confirm proper mounting
