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.
