0.4 mm Pitch, 0.98 mm Mated Height, Board-to-Board / Board-to-FPC Connectors
DF37 Series
1
2010.9
■Features
1. Reduced size and board-occupied area
With the mated height of 0.98 mm, width of 2.98mm and
length of 8.22 mm (30 positions) the connectors are one of
the smallest in its class.Also 2.6mm depth short-lead type is
available.
Sufficiently large flat areas allow pick-up with vacuum
nozzles of automatic placement equipment.
2. Reliable electrical and mechanical connection
Despite its small mated height, unique contact configuration,
with a 2-point contacts and effective mating length of
0.25mm, assures highly reliable connection while confirming
a complete mating with a definite tactile feel.
3. Self alignment
Recognizing the difficulties of mating extremely small
connectors in limited spaces, the connectors will self-align
within 0.3mm.
4. Physical shock and vibration protection
2-point contact assures electrical connection in a shock or
vibration applications.
5. Solder wicking prevention
Nickel barriers (receptacles) and unique forming of the contacts
(headers) prevent un-intentional solder wicking.
6. Contamination protection
Insulator walls protect the contact areas against flux splatter or
other physical particles contamination.

DF37 Series●0.4 mm Pitch, 0.98 mm Mated Height, Board-to-Board / Board-to-FPC Connectors
■Usage Recommendations
Manual soldering: 340±10ç for 3 seconds
Thickness: 0.12 mm
Open area ratio: Receptacle:80%(NB/NC), Plug: 70%
Maximum of 0.02 mm at the connector center, with both ends of the
connector as reference points.
Cleaning is not recommended. When cleaning, please evaluate as it
can deteriorate the performance including mechanical operation and
environmental resistance.
■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.

DF37 Series●0.4 mm Pitch, 0.98 mm Mated Height, 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 opera-
tion 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 illustrat-
ed 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.
