Soldering tips and tricks - temperature measurement during assembling/soldering
This
article presents two video clips about soldering tips and tricks during
electromechanical component assembling. For these videos ULN2xxx DIY KIT PCB
and 4K7 0.25W resistor are used. The measurements are not 100% precise, but example
is clear, it shows that component cooling is much faster by using the external device/tool (like: mini long-nose pliers) in comparison
with cooling at room temperature (25/26 Celsius degrees).
For measurements, DT9208 digital multimeter and thermocouple
sensor/wire are used.
Video #1
Temperature
measurement with digital multimeter thermocouple during soldering. This video
clip presents cooling at room temperature without external cooling device/tool (like: mini long-nose pliers)
after soldering has been done. It also presents how the temperature rises
during soldering process. Soldering started at ~100 Celsius degrees. After
soldering iron has been removed temperature goes down, but it requires more
time to go back to 26 Celsius degrees without external cooling device.
Video #2
Temperature
measurement with digital multimeter thermocouple during soldering. This video
clip demonstrate cooling after the soldering process has been done with the
external cooling device/tool (like: mini long-nose pliers). Soldering started at ~100 Celsius degrees. Cooling is
much faster with external cooling device/tool in comparison with cooling at room
temperature (Video #1).
Measurements and calculations:
Video #1:
--------------
Soldering iron removed @ ~0:16.2 (Temperature was 136 Celsius degrees)
First occurrence of 26 Celsius degrees @ ~1:35.7
Cooling time: ~79.5 seconds
Video #2:
--------------
Soldering iron removed @ ~00:17.4 (Temperature was 139 Celsius degrees)
First occurrence of 26 Celsius degrees @ ~00:47.1
Cooling time: ~29.7 seconds
Difference: ~79.5 - ~29.7 = ~49.8 seconds
Second case with external cooling device/tool cool down temperature ~49.8 seconds faster

Measurements are not 100% precise, but it shows how cooling is faster with the external cooling device/tool. Of course, you will cut the wire after soldering, but you can always cool down soldering join faster with the external cooling device/tool. In some cases it is important to cool down component fastest as it is possible. This does not mean that the ice cubes should be used to cool down components, as components will experience thermal shock.
