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 us 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 coverlay
and adhesive to prevent poor soldering.
This connector has no stand-off.
Therefore, minimize the thickness of the
coverlay, 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
board:
• 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 “PC board recommended
process 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 - 0.3 mm) or
SUS (thickness 0.1 - 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.

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%RH
to 60%RH and please remove static
electricity by ionizer in manufacturing
process.
