Notes on Using Narrow pitch Connectors  
Regarding soldering  
1. Reflow soldering  
Soldering conditions  
2. Hand soldering  
1) Measure the recommended profile  
temperature for reflow soldering by  
placing a sensor on the PC board near  
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.)  
Please use the reflow temperature profile  
conditions recommended below for  
reflow soldering. Please contact us  
before using a temperature profile other  
than that described below (e.g. lead-free  
solder).  
1) Set the soldering iron so that the tip  
temperature is less than that given in the  
table below.

• Narrow pitch connectors  
(except P8 type)  
2) As for cream solder printing, screen  
printing is recommended.  
2) Do not allow flux to spread onto the  
connector leads or PC board. This may  
lead to flux rising up to the connector  
inside.  
3) Touch the soldering iron to the foot  
pattern. After the foot pattern and  
connector terminal are heated, apply the  
solder wire so it melts at the end of the  
connector terminals.

3) To determine the relationship between  
the screen opening area and the PC-  
board foot pattern area, refer to the  
diagrams in the recommended patterns  
for PC boards and metal masks. Make  
sure to use the terminal tip as a reference  
position when setting. Avoid an excessive  
amount of solder from being applied,  
otherwise, interference by the solder will  
cause an imperfect contact.

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 profiles given in this  
catalog are values measured when using  
the connector on a resin-based PC  
board. When performed reflow 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 flux types may  
cause serious solder or flux creeping.  
Solder and flux characteristics should be  
taken into consideration when setting the  
reflow soldering conditions.  
Pattern  
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 fixed to the PC board. (Double  
reflow soldering on the same side is  
possible.)  
6) N2 reflow, conducting reflow soldering  
in a nitrogen atmosphere, increases the  
solder flow too greatly, enabling wicking  
to occur. Make sure that the solder feed  
rate and temperature profile are  
appropriate.  
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 flat tip. To prevent  
flux from climbing up to the contact  
surfaces, do not add more flux.  
3) Keep the soldering iron tip temperature  
below the temperature given in Table A.
