02. Precautions for product design
02-1. Considerations in mechanical design
1) Position of the connector on a board
Rigid boards tend to warp in a direction perpendicular to the rolling direction
during the production process. Poor soldering may occur depending on the
warping direction. Make sure to place the connector in a direction which reduces
warpage.
2) Position of the connector in the mounting process
Please design multi-pins connector layouts that do not require a swinging
movement during pickup and mounting.
In many cases, deviation of the connector mounting position is caused by the
inertia of the swinging movement of the mounter. A layout that does not require
swinging is thus required.
● Example of a connector layout requiring a swinging movement in the mounting process
Make sure that connector positioning and FPC length are appropriate to
prevent diagonal insertion of the FPC. FPC may become loose due to drop
impact and vibration depending on size, weight, and turning of FPC board.
Carefully check the FPC condition in the device. Design the device to prevent
the FPC from detaching.
Poor soldering can be reduced by
designing a mounting pattern to place
the connector in a lateral direction.
Tends to warp in the
manufacturing (lateral) direction.

03. Board arrangement and precautions
for using a fold and cut board
(1)Please design and pay attention to the distance from the board edge to the pattern.
When cutting the v-cut board, do not give an excessive stress to the connector,
which risks damaging the connector.
(2)Please design and pay attention to the range of lever movement and the distance
from the housing PCB.

04. Precautions for FPC insertion and removal
1. Do not touch the lever or apply any load to the lever without inserting an FPC.
Especially do not close the lever without inserting an FPC.
The terminals may be deformed by interference of contacts and the FPC,
because if touching or applying any load to the lever, contact deflection occurs.
Also the lever may come off and FPC insertion force may increase.
2. 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.
3.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.
4. Insert the FPC when the lever is opened vertically as the same state as it delivered .
5. 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.

06. Precautions for board/metalmasking/FPC
design
1) Circuit design
(1) Please apply our recommended PC board pattern, window size and thickness of
metalmasking, reflow soldering temperature profile, in order to appropriate
soldering state. When applying the different dimension of a screen, please contact
us as needed.
Note that excess solder on the terminals prevents complete insertion of the FPC,
and causes flux climbing up.
(2) This connector is provided with a soldering terminal for preventing solder from
peeling off the terminal.
Make sure to design a foot pattern for the soldering terminal.
(3) Pay attention to the following points when
providing a through hole by extending the foot
pattern. If a through-hole is created simply by
extending the foot pattern by the same width,
solder is absorbed into the through-hole during
the reflow process, which may cause defective
or poor soldering of the terminals.
1)Thin and extend the tip of the foot pattern
before creating a through-hole.
2)Prevent solder from reaching the land by
using a coverlay or resist.
(4) Foot pattern dimensions indicated in the drawings
are intended to achieve the minimum area on the
premise that the reflow-soldering process is used.
For manual soldering or for ensuring solder
reworkability, please consider making a longer
pattern at the terminal tip.
However, please apply our recommended
metalmasking dimension. It may cause solder
wicking.
Please check the specification sheet about current
recommended reflow soldering temperature profile.
Soldering terminal
In general, 1/3 the
terminal pattern width
Secure space for applying the
soldering iron tip.
Terminal looseness and unwanted solder
creep are preventable by applying the
soldering iron tip here.
(Please do not solder more than necessary.)

(5) Design the FPC based on the recommended dimensions to ensure
the required connector performance.
(6) There are exposed metal parts on the top of connector.
Please note that the metal parts do not touch other conductive parts
or chassis; otherwise, it may cause short out.
(7) Precautions 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.
2) Metal Mask Design
The size and thickness of this connector have been reduced in order to achieve a
narrow pitch and save space. Therefore, pay attention to the following precautions
for reflow soldering.
(1) In addition to the amount of applied solder, the reflow-soldering environment
and temperature profile affect the finish quality after reflow soldering. Make sure
to adjust the amount of solder applied after checking the finish quality in a test
run.
(2) Compared with natural air reflow soldering, N2reflow soldering can reduce
oxidization of the melted solder surface. This significantly improves the solder
wettability. Therefore, make sure to apply an appropriate amount of solder.
(3) Do not apply an excessive amount of solder, otherwise, solder or flux may creep
near the contact section and reduce contact reliability or cause interference during
lever locking. Pay careful attention.
(4) Check the latest specifications for the metal mask pattern.
Refer to the following page for the current related dimensions.
Please check the specification sheet about current
recommended PC board pattern and metalmasking dimension.

3) FPC Design
(1) Design the FPC based on the recommended dimensions to ensure
the required connector performance.
(2) Make sure that connector positioning and FPC length are appropriate
to prevent diagonal insertion of the FPC.
FPC may become loose due to drop impact and vibration depending on size,
weight, and turning of FPC board. Carefully check the FPC condition
in the device.Design the device to prevent the FPC from detaching.
(3) Precautions for using Y5BW
Do not apply bending load to the cutout part of
FPC. Bending stress is easy to be concentrated
in the cutout part of FPC. And it may cause of FPC
disconnection or deformation.
(4) If you want to check the FPC insertion position,
you are recommended to make the checking
tabs of FPC insertion position. However, please
design (a), (b) dimension yourself on the right
with considering surrounding components.
Please check the specification sheet about current
recommended FPC drawing.

07. Precautions for mounting and reflow soldering
07-1. Points to consider when selecting a pickup nozzle
for mounting
Select a pickup nozzle with a suction area that demonstrates a theoretical lifting force
at least 10 times greater than the connector weight. .
Theoretical lifting force (g) = Vacuum pressure (mmHG) /760 x 1.033 x Nozzle area
(cm2)
Example of machine vacuum pressure setting: 480–520 mmHg
■Picking up the connector
(1) The suction area on the connector is 1.60 mm in the shorter direction.
(2) When picking up the connector, please pay attention that the nozzle do not touch
the lever. Make sure that the nozzle is in the right place. Otherwise, it may cause
suction failure.

07-2. Precautions for reflow soldering
1) Measure the temperature profile at the mounted connector position, and make sure
that it conforms to the recommended profile.
2) 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.
3) When the molded part of connector melts or becomes deformed during the reflow
process, the heating temperature may be too high, or the connector may be
affected by a nearby electronic component with high heat capacity.
4) When the soldering finish is abnormal, check the next points.
If solder creeps to or near the contact section, then excessive solder may have been
applied or the wicking phenomenon may have occurred. Check the amount of
solder applied, the position, and the temperature profile at the mounted connector
position. In particular, be careful not to apply excessive solder when the N2reflow
furnace is used.
5) Extending the screen pattern outward and providing a solder application position
on the outer side can help secure a large front fillet.
Recommended reflow temperature profile
Do not open or close the lever or insert the FPC before soldering.
Applying excessive force on the terminals will result in the loosening
of the terminals from the molded portion, or in the faulty coplanarity.
Do not apply solder to the FPC when it is inserted into the connector.

07-3. Precautions for manual soldering and solder
rework
The size and thickness of this this connector has been reduced in order to achieve
a narrow pitch and save space. Therefore, take a great care when carrying out
manual soldering or rework.
(1) When carrying out manual soldering or rework, make sure that the soldering iron
tip does not contact the molded part. In addition, do not overheat the iron,
otherwise the resin will melt.
(2) During solder rework, solder is supplied at and the soldering iron is applied to the
tip of each pattern. Make sure that solder and the soldering iron do not contact
the terminal.
(3) When carrying out manual soldering or rework, avoid using flux if possible in
order to prevent it from rising to the contact section. (For details, see the next
page.)
When adding more solder, prevent excessive amount of solder.
It may cause solder wicking.
(4) When using flux, apply as little as possible to the tip of the foot pattern. Since this
connector has an ultra-low profile, an excessive amount of flux may cause an
unwanted rise of flux and may result in requiring flux cleaning.
(5) After manual soldering or solder reworking, inspect and check the solder finish
and other abnormalities, such as the adhesion of dispersed flux on the contact,
using a magnifying glass.
Do not open or close the lever or insert the FPC before soldering.
Applying excessive force on the terminals will result in the loosening
of the terminals from the molded portion, or in the faulty coplanarity.
Do not apply solder to the FPC when it is inserted into the connector.

07-4. Detailed precautions for solder rework
(1) Flux-applying tool
To prevent solder creeping to a contact section,
we recommend the use of a brush pen that can
apply an appropriate amount of flux.
(e.g., BON-102F, Japan Bonkote)
(2) Selection of soldering iron
For FPC connector with 0.3-mm pitch, we recommend:
- An iron tip with a retractable-knife shape
Ex. Japan Bonkote
- With a temperature sensor on the iron tip
- Temperature-controllable iron tip
It is also necessary to check that there are no differences between the indicated
temperature and the actual temperature of the iron tip.
The following temperatures are recommended for iron tips:
- Eutectic solder: 300–320˚C
- Lead-free solder of three elements: 340–360˚C
Conventional tool: Dropper
Recommended: Brush pen

07-5. Detailed precautions for manual soldering
(1) General precautions
-When applying flux, apply it thinly on each foot
pattern using a brush pen as shown on the
previous page.
(Place the connector at a predetermined
position after applying flux.)
-The use of a soldering iron with a retractable-
knife shape tip as shown in the previous page
is also recommended.
-While heating with the soldering iron, it is
recommended to slide the iron tip on the foot pattern
along the terminals without touching them.
-Apply the soldering iron to the foot pattern to heat it.
Complete soldering in 1 or 2 seconds.
Connector’s resistance to soldering heat
- 300 °C: 5 sec max.
- 350 °C: 3 sec max.
- Thin wire solder with a diameter of 0.3 - 0.4 mm is recommended.
- Final soldering is recommended after provisionally soldering the terminals at
both ends.
- Note that when the soldering iron touches the terminal, wicking or contact
failure may occur.
(2) Detailed precautions on how to apply the iron tip
(3) Flux cleaning method
Pay attention to the following points when cleaning flux to prevent contact failures
due to the presence of flux:
- To prevent secondary contamination, clean flux using three-chamber cleaning
equipment because contamination of the cleaning agent can be controlled
The pattern length is recommended that
the iron tip does not touch the lead.
Place the iron tip on the end of the foot
pattern,
and apply heat to melt the solder.
Do not touch and push the terminal
with the iron tip, since the contact may
become deformed.
If the iron tip touches and pushes the
terminal end, the contact may also
become deformed.
This must also be avoided.
