Notes on Using Narrow pitch Connectors
Regarding soldering
1. Re?ow soldering
1) Measure the recommended pro?le
temperature for re?ow soldering by
placing a sensor on the PC board near
Soldering conditions
Please use the re?ow temperature pro?le
conditions recommended below for
re?ow soldering. Please contact us
2. Hand soldering
1) Set the soldering iron so that the tip
temperature is less than that given in the
table below.
the connector surface or terminals. (The
setting for the sensor will differ depending
on the sensor used, so be sure to
carefully read the instructions that comes
with it.)
before using a temperature pro?le other
than that described below (e.g. lead-free
solder).

4) Consult us when using a screen-
printing thickness other than that
recommended.
5) When mounting on both sides of the
PC board and the connector is mounting
on the underside, use adhesives or other
means to ensure the connector is
properly ?xed to the PC board. (Double
re?ow soldering on the same side is
possible.)
6) N 2 re?ow, conducting re?ow soldering
in a nitrogen atmosphere, increases the
solder ?ow too greatly, enabling wicking
to occur. Make sure that the solder feed
rate and temperature pro?le are
appropriate.
For products other than the ones above,
please refer to the latest product
speci?cations.
7) The temperatures are measured at the
surface of the PC board near the
connector terminals. (The setting for the
sensor will differ depending on the sensor
used, so be sure to carefully read the
instructions that comes with it.)
8) The temperature pro?les given in this
catalog are values measured when using
the connector on a resin-based PC
board. When performed re?ow soldering
on a metal board (iron, aluminum, etc.) or
a metal table to mount on a FPC, make
sure there is no deformation or
discoloration of the connector beforehand
and then begin mounting.
9) Consult us when using a screen-
printing thickness other than that
recommended.
10) Some solder and ?ux types may
cause serious solder or ?ux creeping.
Solder and ?ux characteristics should be
taken into consideration when setting the
re?ow soldering conditions.

4) Be aware that soldering while applying
a load on the connector terminals may
cause improper operation of the
connector.
5) Thoroughly clean the soldering iron.
6) Flux from the solder wire may get on
the contact surfaces during soldering
operations. After soldering, carefully
check the contact surfaces and clean off
any solder before use.
7) For soldering of prototype devices
during product development, you can
perform soldering at the necessary
locations by heating with a hot-air gun by
applying cream solder to the foot pattern
beforehand. However, at this time, make
sure that the air pressure does not move
connectors by carefully holding them
down with tweezers or other similar tool.
Also, be careful not to go too close to the
connectors and melt any of the molded
components.
8) If an excessive amount of solder is
applied during manual soldering, the
solder may creep up near the contact
points, or solder interference may cause
imperfect contact.
3. Solder reworking
1) Finish reworking in one operation.
2) For reworking of the solder bridge, use
a soldering iron with a ?at tip. To prevent
?ux from climbing up to the contact
surfaces, do not add more ?ux.
3) Keep the soldering iron tip temperature
below the temperature given in Table A.
