About safety remarks
Observe the following safety remarks to prevent accidents and injuries.
Regarding the design of devices and PC board patterns
Notes on Using Narrow pitch Connectors/
High Current Connectors
1) 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.
2) In order to avoid accidents, your thorough specification review
is appreciated. Please contact our sales office if your usage is
out of the specifications. Otherwise, Panasonic Corporation
cannot guarantee the quality and reliability.
3) Panasonic Corporation 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.
1) When using the board to board connectors, do not connect a
pair of board with multiple connectors. Otherwise, misaligned
connector positions may cause mating failure or product
breakage.
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) PC board
Control the thicknesses of the cover lay and adhesive to prevent
poor soldering. This connector has no stand-off. Therefore,
minimize the thickness of the cover lay, etc. so as to prevent the
occurrence of poor soldering.
6) 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.
7) 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.
8) 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.

Regarding the selection of the connector placement machine and the mounting
procedures
Regarding soldering
Reflow soldering
Hand soldering
1) Select the placement machine taking into consideration the
connector height, required positioning accuracy, and packaging
conditions.
2) 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.
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.
6) 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.
1) 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.)
2) As for cream solder printing, screen printing is recommended.
3) 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.
4) Please pay attentions not to provide too much solder. It
makes miss mating because of interference at soldering portion
when mating.
5) 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.)
6) 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.
7) Do not use resin-containing solder. Otherwise, the contacts
might be firmly fixed.
8) Soldering conditions
Please use the reflow temperature profile conditions
recommended below for reflow soldering. Please contact our
sales office before using a temperature profile other than that
described below (e.g. lead-free solder)
For products other than the ones above, please refer to the
latest product specifications.
9) 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 before
mounting.
10) Please contact our sales office when using a screen-printing
thickness other than that recommended.
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) 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.

Storage of connectors
Other Notes
1) Finish reworking in one operation.
2) In case of soldering rework of bridges. Do not use
supplementary solder flux. Doing so may cause contact
problems by flux.
3) Keep the soldering iron tip temperature below the
temperature given in Table A.
1) Make sure not to drop or allow parts to fall from work bench.
2) Excessive force applied to the terminals could cause warping,
come out, or weaken the adhesive strength of the solder. Handle
with care.
3) 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.
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.
There is no need to clean this product.
If cleaning it, pay attention to the following points to prevent the
negative effect to the product.
1) Keep the cleaning solvent clean and prevent the connector
contacts from contamination.
2) Some cleaning solvents are strong and they may dissolve the
molded part and characters, so pure water passed liquid solvent
is recommended.
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 force.
1) To prevent problems from voids or air pockets due to heat of
reflow soldering, avoid storing the connectors in areas of high
humidity.
2) 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.
3) 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.
4) Avoid storing the connectors in locations with excessive dust.
The dust may accumulate and cause improper connections at
the contact surfaces.
1) Do not remove or insert the electrified connector (in the state
of carrying current or applying voltage).
2) Dropping of the products or rough mishandling may bend or
damage the terminals and possibly 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) Product failures due to condensation are not covered by
warranty.
