About safety remarks
PC board design
FPC/FFC and equipment design
Notes on Using FPC/FFC Connectors
1) Do not use these connectors beyond the specification sheets.
The usage outside of specified rated current, dielectric strength,
and environmental conditions and so on may cause circuitry
damage via abnormal heating, smoke, and fire.
2) In order to avoid accidents, your thorough specification review
is appreciated. Please contact our sales office if your usage is
out of the specifications. Otherwise, Panasonic Corporation
cannot guarantee the quality and reliability.
3) Panasonic Corporation is consistently striving to improve
quality and reliability. However, the fact remains that electrical
components and devices generally cause failures at a given
statistical probability. Furthermore, their durability varies with
use environments or use conditions. In this respect, please
check for actual electrical components and devices under actual
conditions before use.
Continued usage in a state of degraded condition may cause the
deteriorated insulation, thus result in abnormal heat, smoke or
firing. Please carry out safety design and periodic maintenance
including redundancy design, design for fire spread prevention,
and design for malfunction prevention so that no accidents
resulting in injury or death, fire accidents, or social damage will
be caused as a result of failure of the products or ending life of
the products.
1) Design the recommended foot pattern in order to secure the
mechanical strength in the soldered areas of the terminal.
2) In order to facilitate the connector mount, make sure to design
the board with reduced warpage.
3) Please design and pay attention to the distance from the
board edge to the pattern. When cutting the board, do not give
an excessive stress to the connector, which risks damaging the
connector.
4) Y3BW/Y5BW
Depending on FPC/FFC dimension and FPC/FFC insertion
location, there is a possibility that the holding contact and an
FPC/FFC pattern of both end of signal contacts are in short-
circuited. Please design the equipment not to be affected even if
a board pattern of holding contacts and an FPC/FFC pattern of
both end of signal contacts are in short-circuited.
(For example: Do not connect a board pattern of holding
contacts and GND.
If connect a board pattern of holding contacts and GND, also
connect board pattern of both end of signal contacts.)
1) Design the FPC/FFC based with recommended dimensions
to ensure the required connector performance.
2) When back lock type is used, secure enough space for
closing the lever and for open-close operation of the lever.
3) Make sure that connector positioning and FPC/FFC length
are appropriate to prevent diagonal insertion of the FPC/FFC.
4) Due to the FPC/FFC size, weight, or the reaction force of the
routed FPC/FFC, FPC/FFC removed and connector deformation
may occur by a fall, vibration, or other impact.
When using FPC/FFC connector for smart phones, cellular
phones and other applications which require falling resistance,
please pay attention to precautions.
5) Carefully check the equipment design and take required
measures to prevent the FPC/FFC removed.
6) If the shock of falling, vibration is applied to the FPC/FFC,
please design the equipment not to be applied a load to
connector, such as fixing the FPC/FFC.
7) Make sure to design the FPC/FFC insertion part with reduced
warpage. Otherwise, the warpage may adversely affect the FPC/
FFC insertion.
8) Y4BH, Y5BH
When using in high-speed transmission applications, please
take care when designing the FPC/FFC, because the differential
impedance values may be uneven depending on FPC/FFC
dimensions settings, uneven dimensions, and layering
composition.
9) Y3BW/Y5BW
The holding contacts cannot be used as conductors.
The holding contacts are located on both ends of the
connector, and the shape of the soldered portions is the
same as that of the signal contacts. Use caution to ensure
connect identification.
10) Y3BL
Soldering terminal structure
• Since soldering terminals touch FPC/FFC, note that the short
circuit may occur when the metal parts exposed on side of FPC/
FFC.
• Depending on FPC/FFC dimension, there is a possibility that
soldering terminals and an FPC/FFC pattern of both end of
signal contacts are in short-circuited. Please design the
equipment not to be affected even if a board pattern of soldering
terminals and an FPC/FFC pattern of both end of signal contacts
are in short-circuited.
(For example: Do not connect a board pattern of soldering
terminals and GND.
If connect a board pattern of soldering terminals and GND, also
connect board pattern of both end of signal contacts.)

Connector mounting
Soldering
1. Manual soldering
2. Reflow soldering
3. Rework of soldering portion.
1) Excessive mounter chucking force may deform the molded or
metal part of the connector. Consult us in advance if chucking is
to be applied.
2) In case of dry condition, please note the occurrence of static
electricity. The product may be adhered to the embossed carrier
tape or the cover tape in dry condition. Recommended humidity
is from 40 to 60%RH and please remove static electricity by
ionizer in manufacturing process.
1) As this product is compact size, please avoid the excessive
solder. Because the excessive solder makes creepage and flux
wicking at contact portion, or impact contact by soldering
interference.
2) Please use the soldering iron under specified temperature
and times.
3) Soldering flux may contaminate the contact portion, please
check the contact portion after soldering with a magnifying
glass. If the contamination is found, please clean the
contamination before use.
4) As excessive force to terminal by manual soldering has some
possibilities of contact portion deformation, please be careful to
the force by hand.
5) Please clean soldering iron tip.
1) When cream solder printing is used, screen method is
recommended.
2) 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.
3) Note that excess solder on the terminals prevents complete
insertion of the FPC/FFC, and causes flux climbing up.
4) A screen thickness of 120μm is recommended during cream
solder printing.
5) When applying the different thickness of a screen, please
contact our sales office.
6) There may be a case of difficult self-alignment depending on
the connector size. In that case, please be careful to align
terminals and solder pads.
7) The following diagram shows the recommended reflow
soldering temperature profile.
8) Infrared reflow soldering is able to passed two times.
9) The temperature is measured on the PC board surface near
connector terminals.
10) The condition of solder or flux creepage and wettability
depend on the type of solder and flux. Please set the reflow
temperature and oxygen level by considering the solder and flux
characteristics.
11) Do not use resin-containing solder. Otherwise, the contacts
might be firmly fixed.
12) 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 apply reflow heating while a lever is closing (or on
the way of closing)
The terminals may be deformed by reflow heating with a lever is
closing (or on the way of closing).

3) Please use the soldering iron under specified temperature.
4. As the excessive force on the terminals may cause the
deformation and the integrity of solderability will be lost
during reflow soldering, please avoid dropping or rough
handling of the product.
5. When the soldering is not completed, do not open/close
the lever or insert/ remove an FPC/FFC. And the external
compulsory force to the terminal may cause the fixing force
lowering between the terminal and the molding or the
coplanarity failures. In addition, do not insert an FPC/FFC
into the connector before soldering the connector.
6. When cutting or bending the PC board after mounting the
connector, please avoid the stress at the soldering portion.

Notes on Using FPC/FFC Connectors
–3– ACCTB13E 201803-T
PC board
Precautions for insertion/removal of FPC/FFC
1) As thick coverlay/solder resist and adhesive may cause poor
soldering, please set thickness of coverlay and adhesive as thin
as possible.
1) (Except for Y3BC)
Avoid touching the lever (applying any external force) until an
FPC/FFC is inserted. Do not open/close the lever without an
FPC/FFC 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/FFC, deforming the terminals. Failure to
follow this instruction may cause the lever to be removed,
terminals to be deformed, and/or the FPC/FFC insertion force to
increase.
2) These connectors are of the back lock type, which has the
FPC/FFC insertion section on the opposite side of the lever. Be
careful not to make a mistake in the FPC/FFC insertion position
or the lever opening/closing position. Otherwise, a contact failure
or connector breakage may occur.
3) Do not insert an FPC/FFC upside down. Inserting an FPC/
FFC in a direction opposite to that you intended may cause an
operation failure or malfunction.
4) Insert an FPC/FFC with the lever opened at right angle, that
is, in the factory default position.
5) After checking the position of FPC/FFC insertion slot and
FPC/FFC, completely insert the FPC/FFC horizontally to the full
depth of the connector without altering the angle. An FPC/FFC
inserted at an excessive angle to the board may cause the
deformation of metal parts, crack of molding parts, FPC/FFC
insertion failures, and FPC/FFC circuit breakages.
6) Insert the FPC/FFC into the connector after checking the
position of FPC/FFC insertion slot and FPC/FFC. Do not insert
the FPC/FFC without positioning the FPC/FFC and connector.
Otherwise, it may cause connector breakages. When it is hard to
insert the FPC/FFC, do not insert the FPC/FFC on that
condition. Confirm the FPC/FFC and connector positioning.
7) 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.
8) 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.
9) 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 or lever going back
to initial position. Close the lever completely to prevent contact
failure.
10) Avoid applying an excessive load to the top of the lever
during or after closing the lever. Otherwise, the terminals may be
deformed.
11) When opening the lever to remove the FPC/FFC, rotate the
lever to the initial position. Do not push the lever into the FPC/
FFC inlet side and ensure that the lever will not go over the initial
position; otherwise, it may be deformed or broken.
12) To open the lever, if pressure to the lever is applied unevenly,
such as to an edge only, it may deform or break.
13) Do not open the lever forcefully with something sharp tool,
otherwise, the lever may be deformed.
14) Remove the FPC/FFC at parallel with the lever fully opened.
If the lever is closed, or if the FPC/FFC is forcedly pulled, the
product or FPC/FFC may break.
15) If a lever is accidentally detached during the handling of a
connector, do not use the connector any longer.
1. After an FPC/FFC is inserted, carefully handle it so as not
to apply excessive stress to the base of the FPC/FFC. When
using FPC/FFC 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/FFC disconnection.
16) Design so that a load is not applied to connector directly by
FPC/FFC bending.
17) Avoid sharp FPC/FFC bending at the root of FPC/FFC
insertion part.
18) Design so that a load is not applied to the part of FPC/FFC
bending.
19) If there might be a load on FPC/FFC, please fix the FPC/
FFC.
20) Y3BW and Y5BW
Fix the FPC/FFC if there might be a load to the cut out, do not
apply bending load to the cutout part of FPC/FFC. Otherwise, it
may cause FPC/FFC disconnection and deformation since the
cutout part of FPC/FFC is subjected to bending stress.
