Notes on Using FPC Connectors
■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 with recommended dimensions to
ensure the required connector performance.
• When using back lock type, secure enough space for closing
the lever and for open-close operation of the lever.
• Make sure that connector positioning and FPC length are
appropriate to prevent diagonal insertion of the FPC.
Due to the FPC size, weight, or the reaction force of the routed
FPC, FPC may be removed. Carefully check the equipment
design.
Ta ke required measures to prevent the FPC from being removed
due to a fall, vibration, or other impact.
(Y3BW/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.
Use caution to ensure connect identification.
(Y3BL)
■Soldering terminal structure
Since soldering terminals touch FPC, note that the short circuit
may occur when the metal parts exposed on side of FPC.
■Connector mounting
Excessive mounter chucking force may deform the molded or
metal part of the connector. Consult us in advance if chucking is
to be applied.
■Soldering
1) Manual soldering
• Due to the connector’s compact size, if an excessive amount of
solder is applied during manual soldering, the solder may creep
up and flux wicking near the contact points, or solder
interference may cause contact failure.
• Make sure that the soldering iron tip is heated within the
temperature and time limits indicated in the specifications.
• Flux from the solder wire may adhere to the contact surfaces
during soldering operations. After soldering, carefully check the
contact surfaces and cleans off any flux solder 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.
• To achieve the appropriate soldering state, make sure that the
reflow temperature, PC board foot pattern, window size and
thickness of metal mask are recommended condition.
• Note that excess solder on the terminals prevents complete
insertion of the FPC, and causes flux climbing up.
• A screen thickness of 120µm is recommended during cream
solder printing.
• 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 terminals.
• Depending on reflow condition, poor contact may occur by
solder and flux wicking.
Please set the reflow conditions that considering the
characteristics of solder and flux. Also please make
consideration in setting the reflow times and O2 concentration to
prevent poor contact by solder and flux wicking.
• 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 reflow soldering on the same side is possible.)
Do not touch the lever or apply any load to the lever until the
second reflow soldering. Otherwise, contact deflection occurs
and the terminals may be deformed by reflow heating.
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.
When adding the solder for reworking, do not add an excessive
solder. Otherwise, solder and flux may creep up and solder
bridges may occur.
• Use a soldering iron whose tip temperature is within the
temperature range specified in the specifications.
■Do not drop or handle the connector carelessly.
Otherwise, the terminals may become deformed due to
excessive force or applied solderability may be during
reflow degrade.
■Do not 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 force.

Notes on Using FPC Connectors
ACCTB13E 201303-T
■Precautions for insertion/removal of FPC
<Front-Lock>
• To open the lever, hold its center and pull it up. An uneven load
applied to the lever on one side may deform and break the lever.
Do not apply an excessive load to the lever in the opening
direction, otherwise, the terminals may be deformed.
• Don’t further apply an excessive load to the fully opened lever;
otherwise, the lever may be deformed.
• Fully open the lever to insert an FPC.
• Since this product connects at the bottom, please insert the
FPC so that its electrode plane is facing the board to which it will
be mounted. Do not insert the FPC in the reverse direction of the
contact section; otherwise, operation failures or malfunctions
may be caused.
(Y3FT)
• This product has a structure to position an inserted FPC using
the FPC tabs.
Therefore, insert an FPC at an angle to the board. If the FPC is
inserted in the direction parallel to the board, the molded
positioning parts block the FPC, leading to incomplete insertion.
Do not insert the FPC at an excessive angle to the board.
Otherwise, it may cause the deformation of metal parts, FPC
insertion failures, and FPC circuit breakages.
(Y3F)
• Completely insert the FPC horizontally. Do not insert the FPC
at an excessive angle to the board. Otherwise, it 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.
• When closing the lever, carefully use the tip of your finger to
push the entire lever or both sides of it. If pressure to the lever is
applied unevenly, IE: only the edge, it may deform or break the
FPC. Make sure that the lever is closed completely. Not doing so
will cause a faulty connection.
• Avoid applying an excessive load to the top of the lever during
or after closing the lever. Otherwise, the terminals may be
deformed.
• Remove the FPC at an angle with the lever fully opened. If the
lever is closed, or if the FPC is forcedly pulled into a direction
parallel to the board, the molded part may break.
<Back-Lock>
• Avoid touching the lever (applying any external force) until an
FPC is inserted.
Do not open/close the lever without an FPC inserted. Failure to
follow this instruction will cause the contacts to warp, leading to
the contact tips to interfere with the insertion of an FPC,
deforming the terminals. Failure to follow this instruction may
cause the lever to be removed, terminals to be deformed, and/or
the FPC insertion force to increase.
• The FPC insertion section is 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.
• 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.
• Insert an FPC with the lever opened at right angle, that is, in
the factory default position.
• 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.
• Insert the FPC into the connector after checking the position of
FPC insertion slot and FPC. Do not insert the FPC without
positioning the FPC and connector. Otherwise, it may cause
connector breakages. When it is hard to insert the FPC, do not
insert the FPC on that condition. Confirm the FPC and
connector positioning.
• 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 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.
• To close the lever, turn down the lever by pressing the entire
lever or both sides of the lever with fingers tips. And close the
lever completely. Be careful not to apply partial load to the lever
that may cause its deformation or destruction.
Close the lever completely to prevent contact failure.
• If pressure to the lever is applied unevenly, it may deform or
break the FPC. Make sure that the lever is closed completely.
Not doing so will cause a faulty connection.
• Avoid applying an excessive load to the top of the lever during
or after closing the lever. Otherwise, the terminals may be
deformed.
• When opening the lever to remove the FPC, ensure that the
lever will not go over the initial position; otherwise, the lever may
be removed.

Notes on Using FPC Connectors
ACCTB13E 201303-T
• 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. When using
FPC with a bent condition, please pay attention to
precautions below; otherwise, in some conditions it may
cause conduction failure, connector breakage, unlocking
lever or FPC disconnection.
• Design so that a load is not applied to connector directly by
FPC bending.
• Avoid sharp FPC bending at the root of FPC insertion part.
• Design so that a load is not applied to the part of FPC bending.
• Fix the FPC if there might be a load on FPC when using the
FPC with cutout, do not apply a bending load to the cutout part
of FPC. Otherwise, it may cause FPC disconnection and
deformation since the cutout part of FPC is subjected to bending
stress.
■Other cautions
• When coating the PC board after soldering the connector (to
prevent the deterioration of insulation), perform the coating in
