2. Strong resistance to adverse
environments! Utilizes
“
for high contact reliability.
1) Contacts are highly resistant to shock
caused by dropping and employ our
original bellows contact construction.
2) V notch construction used for excellent
resistance against foreign matters.
3) Use of Ni barrier construction is
standard. Highly effective against solder
creeping.
Note: If extra resistance to drop impact is required,
● Ni barrier
The exposed nickel-plated portion of the
gold-plated contact prevents solder creep
despite the ultra low profile of the contact.

Note: Simultaneous molding of the header contact
● V-notch
By making contact with the edges and thus
increasing the contact pressure, this pro-
duct can eliminate flux and other foreign
matters more effectively than conventional
products, which also helps to prevent for-
eign matters from obstructing the contact.

FOR BOARD-TO-BOARD
Socket side contact
Contacts are formed by
bending a thin metal sheet,
which provides the contact
parts with adequate spring
characteristics ensuring
greater resistance to prying
forces and drop impacts.
AND BOARD-TO-FPC
we recommend using our P4 series.
achieves a construction that prevents solder creep.

4) Porosity treatment applied for
improved resistance against corrosion.
3. Greater flexibility in connector
placement.
Pattern wiring to the connector bottom is
possible because the undersurface of the
connector is constructed with a molded
covering.

4. Automatic mounting inspection is
facilitated by the gull-wing terminal
shape which makes mounting
verification easy.
5. Connectors for inspection available
Connectors are available that are ideal
for inspection in module unit inspection
and device assembly processes.

● Porosity treatment
This treatment consists in coating the sur-
face with a very thin film to seal pinholes in
the gold plating. We have developed this
porosity treatment technology, which en-
sures contact reliability for thin gold plating
comparable to that of thick gold plating.
● Improvement in insertion/removal durability
● Improvement in resistance to corrosion
● Improvement in contact reliability for digital signals
