4. Effective mating length 0.3 mm
3) Use of Ni barrier construction is
standard. Highly effective against solder
creeping. (Available from Nov. 2005)
ꢀ What is Ni barrier construction?
Socket
Header
By providing an exposed nickel part on the
gold (Au) plated contact, solder creeping is
prevented despite the ultra low profile.

5. Compliance with RoHS’ Directive
Environmentally friendly, the connectors’
comply with Europe’s RoHS’ Directive.
Cadmium, lead, mercury, hexavalent,
chromium, PBB and PBDE are not used.

1. Low profile mating height of 1.2 mm
with 0.5 mm pitch, was obtained.
It contributes to device compactness.
2. Strong resistance to adverse
environments! Utilizes
construction
for high contact reliability.
1) Contacts are highly resistant to shock
caused by dropping and employ our
original bellows contact construction.

APPLICATIONS
Socket side contact
• Cellular phones
• PHS
Note: Construction makes solder creeping difficult
because header side is formed at the same time.
• Portable data terminals
• Digital cameras
• Compact portable devices
4) Porosity treatment applied for
improved resistance against corrosion.
Ideal for Board-to-FPC connections
What is porosity treatment?
FPC
Reinforcing plate
This treatment consists of coating the
surface with a very thin film to seal pinholes
in the gold plating. This porosity treatment
technology ensures the same contact
reliability for thin gold plating as that of thick
gold plating.

Since the contact is

formed by bending thin
plate, it has a spring-like
quality. This structure
makes it resistant to
dropping and twisting.
The simple lock
This enables the number of pins to
be doubled white the size remains
the same as that for existing FPC
connectors. This, in turn, contributes
to making products and equipment
more compact.
mechanism ensures
that the connector
clicks into position
when it is inserted for
reliable single-action
insertion on the PCB.

2) V notch construction used for excellent
resistance against foreign matters.
Ni plating
ꢀ What is V notch construction?
Base material
By using the edge for the contacting part
and increasing contact pressure per unit
area, the effectiveness in removing flux
and contaminants is increased compared
to its predecessor. This is also effective in
preventing the trapping of contaminants.
