FEATURES
• Low profile, space saving back lock
type with improved lever operability
• Mechanical design freedom achie ved
by top and bottom double contacts
• Low profile, space saving design
with a wide selection, including a type
with a small number of contacts
Low profile and space sa ving body of 1.0
mm high and 3.20 mm deep (3.70 mm
including the lever)
Y5B and Y5BW can have a minimum of
four and two contacts respectively,
contributing to the miniaturization and
thickness reduction of target equipment.
Wiring patterns can be located
underneath the connector.
• Man-hours for assembly can be
reduced by delivering the connectors
with their levers opened.
Y5BW features advanced
functionality, including a structure to
temporarily hold the FPC and a higher
holding force.
The FPC holding contacts located on
both ends of the connector facilitate
positioning of FPC and further enhance
the FPC holding force.
APPLICATIONS
A wide range of digital equipment,
including mobile phones, PCs, DSCs,
and DVCs. Ideal for their touch panels
and LCD backlights, which require
connectors with a small number of
contacts.

notches on both ends
of the FPC with
holding contacts
(1) The holding contacts lock the FPC by its through-holes or
notches, allowing users to confirm the completion of the
FPC insertion operation.
(2) The inserted FPC can be temporarily held until the lever is
closed.
(3) When the lever is closed, the holding contacts lock the
FPC by its through-holes and notches, enhancing the FPC
holding force.

1. Recommended PC board and metal mask patterns
Appropriate control of solder amount is required to minimize
solder bridges and other defects for connectors with 0.3 mm or
0.5 mm pitch terminals, which require high-density mounting.
Refer to the recommended PC board pattern.
• Y5B
• Y5BW
2. Precautions for insertion/removal of FPC
Do not apply an excessive load to the lever in the opening
direction beyond its open position; otherwise, the lever may be
deformed or removed.
Do not open/close the le ver without an FPC inserted; otherwise,
the terminals may be deformed, and the FPC insertion force
may increase.
Do not apply an excessive load to the lever in a direction
perpendicular to the lever rotation axis or in the lever opening
direction; otherwise, the terminals may be deformed, and the
lever may be removed.
These connectors are of the back lock type, which has the FPC
insertion section on the opposite side of the lever . Be careful not
to make a mistake in the FPC insertion position or the lever
opening/closing position. Otherwise, a contact failure or
connector breakage may occur.
These connectors have top and bottom double contacts. Do not
insert an FPC upside down. Inserting an FPC in a direction
opposite to that you intended may cause an operation failure or
malfunction.
Fully open the lever to insert an FPC.
Completely insert the FPC horizontally. An FPC inserted at an
excessive angle to the board may cause the deformation of
metal parts, FPC insertion failures, and FPC circuit breakages.
Insert the FPC to the full depth of the connector without altering
the angle.
To close the lever, turn down the lever by pressing the entire
lever or both sides of the lever with the balls of fingers.
Be careful. If pressure to the lever is applied unevenly, such as
to an edge only, it ma y def orm or break. Also , mak e sure that the
lever is closed completely. Not doing so will cause a faulty
connection.
Avoid applying an excessiv e load to the top of the le v er during or
after closing the lever. Otherwise, the terminals may be
deformed.
When opening the lever to remove the FPC, ensure that the
le ver will not go over the initial position; otherwise, the lever may
be removed.
Remove the FPC at parallel with the lever fully opened. If the
lever is closed, or if the FPC is forcedly pulled, the product or
FPC may break.
If a lever is accidentally detached during the handling of a
connector, do not use the connector any longer.
After an FPC is inserted, carefully handle it so as not to apply
excessive stress to the base of the FPC.
3. Cautions for using Y5BW
The holding contacts cannot be used as conductors.
The holding contacts are located on both ends of the contacts,
and the shape of the soldered portions is the same as that of the
other contacts. Therefore, be careful to avoid any confusion.

FPC CONNECTORS COMMON CAUTIONS FOR USE
COMMON CAUTIONS FOR USE
PC board design
Design the recommended foot pattern in
order to secure the mechanical strength
in the soldered areas of the terminal.
FPC and equipment design
Design the FPC based on the
recommended dimensions to ensure the
required connector performance.
In addition, carefully check the equipment
design and take required measures for
the equipment to prevent the FPC from
being removed subsequent to a fall,
vibration, or other impact due to the FPC
size, weight, or the reaction force of the
routed FPC.
Connector mounting
In case the connector is picked up by
chucking during mounting, an excessive
mounter chucking force may deform the
molded or metal part of the connector.
Consult us in advance if chuc king is to be
applied.
Soldering
1) Manual soldering.
• Due to the low profile, if an excessive
amount of solder is applied to this
product during manual soldering, the
solder may creep up to near the contact
points, or interference by solder may
cause imperfect contact.
• Make sure that the soldering iron tip is
heated within the temperature and time
limits indicated in the specifications.
• Flux from the solder wire ma y adhere to
the contact surfaces during soldering
operations. After soldering, carefully
check the contact surfaces and clean off
any flux before use.
• Be aware that a load applied to the
connector terminals while soldering may
displace the contact.
Thoroughly clean the iron tip.
2) Reflow soldering
• Screen-printing is recommended for
printing paste solder.
Y3FT/Y3F/Y3B/Y5F/Y5B/Y5BW
Y5S
Y3FT/Y3F/Y3B/Y5S/Y5B/Y5BW
• Consult us when using a screen-printing
thickness other than that recommended.
• Depending on the size of the connector
being used, self alignment may not be
possible. Accordingly, carefully position
the terminal with the PC board pattern.
The recommended reflow temperature
profile is given in the figure below

The temperature is measured on the
surface of the PC board near the
connector terminal.
• Some solder and flux types may cause
serious solder creeping. Take the solder
and flux characteristics into consideration
when setting the reflow soldering
conditions.
When performing reflow soldering on
the back of the PC board after reflow
soldering the connector, secure the
connector using, for example, an
adhesive . (Double reflo w soldering on the
same side is possible)
3) Reworking on a soldered portion
• Finish reworking in one operation.
• For reworking of the solder bridge, use
a soldering iron with a flat tip. Do not add
flux, otherwise, the flux may creep to the
contact parts.
• Use a soldering iron whose tip
temperature is within the temperature
range specified in the specifications.
Do not drop the product or handle
carelessly. Otherwise, the terminals
may become deformed due to
excessive force or the solderability
during reflow soldering may degrade.
Don’t open/close the lever or insert/
remove an FPC until the connector is
soldered. Forcibly applied external
pressure on the terminals can weaken
the adherence of the terminals to the
molded part or cause the terminals to
lose their evenness. In addition, do
not insert an FPC into the connector
before soldering the connector.
When cutting or bending the PC
board after mounting the connector,
be careful that the soldered sections
are subjected to excessive forces.
Other Notes
When coating the PC board after
soldering the connector to prevent the
deterioration of insulation, perform the
coating in such a way so that the coating
does not get on the connector.
The connectors are not meant to be used
for switching.
To determine the relationship between
the screen opening area and the PC
board foot pattern area, refer to the
diagrams in the recommended
patterns for PC boards and metal
masks when setting.
Note that excess solder on the
terminals prevents complete insertion
of the FPC, and that e xcess solder on
the metal clips pre v ents the lever from
rotating.
Note that excess solder inhibits the
slider lock operation.
Screen thickness of 120µm is recom-
mended for paste solder printing.
