3) Use of Ni barrier construction is
standard. Highly effective against solder
creeping. (Available from Oct. 2005)
G What is Ni barrier construction?
By providing an exposed nickel part on the
gold (Au) plated contact, solder creeping is
prevented despite the ultra low profile.

1. The connector is a two-piece
structure and 0.5mm pitch.
The product lineup consists of the mated
height of 1.5mm, 2.0mm and 2.5mm.
2. Strong resistance to adverse
for high contact reliability.
1) The socket and header has the same
dropping shock and torsion resistant
construction as the bellows-type contact.
Since the contact is formed
by bending thin plate, it
has a spring-like quality.
This construction helps
make it resistant to
dropping and twisting.
2) V notch construction used for excellent
resistance against foreign matters.
G What is V notch construction?
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.

4) Porosity treatment applied for
improved resistance against corrosion.
What is porosity treatment?
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
Porosity treatment film
G Improvement in insertion/removal durability
G Improvement in resistance to corrosion
G Improvement in contact reliability for digital signals
3. Simple locking structure
Superior mating operation with click
feel to indicate that mating is

4. Mating length 0.55mm
While achieving a low proﬁle of 1.5mm
between PCBs, the effective mating
length has been extended to ensure that
there is some latitude in the mating.
5.The lower connector bottom surface
construction prevents contact and
shorts between the PCB and metal
This enables freedom in pattern
wiring, helping to make PCB’s smaller.
Connector bottom: Create any thru-hole and pattern wiring.
6. Automatic mounting inspection is
facilitated by the gull-wing terminal
shape which makes mounting
7. 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.
8. Connectors for inspection available
Connectors for inspection are available
that are ideal for modular unit inspection
and inspection in device assembly
• Cellular phones
• Portable data terminals
• Digital cameras
• Compact portable devices
Ideal for Board-to-FPC connections
The simple lock
that the connector
clicks into position
when it is inserted for
insertion on the PCB.
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
