NARROW-PITCH, THIN AND
SLIM CONNECTOR FOR
BOARD-TO-FPC
CONNECTION
NARROW PITCH (0.4 mm)
CONNECTORS F4S SERIES
FEATURES
1. Space-saving (3.6 mm widthwise)
The required space is smaller than our
F4 series (40-contact type):
Socket — 27% smaller,
Header — 38% smaller
The small size contributes to the
miniaturization of target equipment.
* Clips for preventing the solder joints from being removed
2. Highly reliable
has strong
resistance to adverse environments.
1) Our original bellows contact: High
resistance to drop impact and twisting
forces.
Note: If extra resistance to shock caused by dropping
is required, we recommend using our previous
F4 Series.
2) V-notch + double contact:
High resistance to the penetration of
foreign matters and flux.
3) Ni barrier: High resistance to solder
creep.
4) Porosity treatment: Resistance to
corrosion.
3. The simple lock structure gives
tactile feedback that ensures a
superior mating/unmating operation
feel.
4. Gull-wing type terminals
The gull-wing type terminals facilitate
automatic mounting inspections.
5. RoHS Directive compliance.

phones, DVC, Digital cameras, etc”

Double contact
Contacts are formed by
bending a thin metal sheet.
This provides the contact
parts with adequate spring
characteristics ensuring
greater resistance to twisting
forces and drop impacts.
● 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.

● 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
achieves a construction that prevents solder creep.

Porosity treatment
Au plating Ambient gas
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.

NOTES
1. If extra resistance to drop impact is
required, we recommend using our F4
series.
2. Recommended PC board and metal
mask patterns
Appropriate control of solder amount is
required to minimize solder bridges and
other defects for connectors with 0.4-mm
or 0.5-mm pitch terminals, which require
high-density mounting. Refer to the right-
hand drawing for recommended patterns.
