0.4 mm Contact Pitch,Stacking Height 0.6mm 0.8mm Board-to-Board /Board-to-FPC Connectors
BM10 Series
2010.9
■Features
1. Higher density of the board-mounted
components
Extremely small board mounting pattern and low abovethe-
board profile makes the connectors ideally suited for small
device applications.
Globally unrivalled compact depth:when mated 2.98mm
Header 2.46mm
Length - world’s smallest class:10.4mm
2. Reliable electrical and mechanical connection
Despite its small mated height, unique contact configuration,
with a 2-point contacts and effective mating length of
0.2mm(height 0.8mm)and 0.1mm(height 0.6mm), assures
highly reliable connection while confirming a complete mating
with a definite tactile feel.
3. Large self-alignment distance
The connectors will self-align within 0.3 mm.
4. Built-in shock absorbing feature
The protrusions and indents in the insulator bodies protect the
connectors from failures when exposed to sudden impact.
5. Solder wicking prevention
Nickel barriers prevent un-intentional solder wicking.
6. Contamination protection
Insulator walls protect the contact areas against flux splatter or
other physical particles contamination.
7. Conducive traces on the PCB can run under
the connector
No exposed contacts on the bottom of the connector.
Contact areas are not exposed to the outside
penetration of the flux or other physical particles.

■Usage Recommendations
Manual soldering: 340±10ç for 3 seconds
H=0.8mm Header, Receptacle :Thickness 0.12mm
:Open area ratio 100%
* When using nitrogen-reflow, 75% only at the header side.
H=0.6mm Header Thickness 0.1mm
Receptacle 0.12mm:Open area ratio 100%
* When using nitrogen-reflow, 75% only at the header side.
Maximum of 0.02 mm at the connector center, with both ends of the
connector as reference points.
Refer to “Nylon Connector Use Handbook”.
■ Mating and un-mating of the connectors when not soldered on the
boards is not recommended as this may cause deformation of the
terminals, damage to the contacts or insulators.
■ Mated connectors should not carry weight of the board by
themselves. Provide some other support of the boards.
■ When mating/un-mating do not twist or lift by the corners. Apply the
forces evenly across the entire length and width of the connectors
taking care NOT to damage or deform soldered terminations.
■ Exercise extreme caution when mating/ un-mating when the
connector is mounted on a nonrigid (flexible) substrate.
Slight discoloration on the insulating materials will not affect form,
fit or function of the connectors.
■ Do NOT pull on the flexible substrate.
Note 1: Up to 2 cycles of Reflow soldering are possible under the
same conditions, provided that there is a return to normal
temperature between the first and second cycle.
Note 2: The temperature profile indicates the board surface
temperature at the point of contacts with the connector
terminals.

■Handling Precautions when Mating Connectors
Keep the connectors parallel to each other
when positioning. The connectors will self-
align in horizontal directions.
Do not attempt to mate the connectors starting
at one end or side.
Press-down even until fully mated.

BM10 Series●0.4 mm Contact Pitch,Stacking Height 0.6mm 0.8mm Board-to-Board /Board-to-FPC Connectors
Fully mated
Lift even, keeping both connectors parallel to
each other
When handling, circumstances may prevent
the connectors from being kept parallel when
un-mating. One end may be lifted as shown.
However, to use this procedure the connector
must be mounted on sufficiently rigid circuit
board.
Any deflection of the board during this
operation may result in damage to the
connector or solder joints.
Do not attempt to start the un-mating of the
connectors from one side or corner.
Failure to exercise caution when un-mating
the connectors mounted on the non-rigid FPC
may also result in connector breakage.
It is the responsibility of the user to perform
verification of the repeated mating / un-mating
cycles with the connectors mounted on the
applicable FPC.
When the rigidity of the FPC is low, there is a
risk that the connector could break as
illustrated in the diagram at left.
Please use the connectors after performing a
check of repeated operation with the FPC that
the customer will be using.
Evaluative results of FPC rigidity and various
items are available. Please inquire.
