③Measure the temperature curve of reflow soldering and fix the thermocouple:

After selecting the tested point, the thermocouple shall be installed at the tested point.

Generally, there are several methods as follows:

The thermocouple is fixed by solder, and the high temperature solder with high Pb content is generally used to fix the thermocouple at the tested point.

It is required that the solder joints should be as small as possible, because the solderability of high-temperature solder is not high,

therefore, the operator should have the high welding skills, and the thermal impact on components is also large because of high-temperature welding. The effect of temperature measurement is better.

Use adhesive to fix, generally use epoxy resin adhesive to fix the thermocouple at the tested point. The glue point should be as small as possible. The effect of temperature measurement is general.

We should apply the High temperature tape to fix the thermocouple, what is more the tape should be with high temperature resistance and good thermal conductivity. Also, it needs to keep the thermocouple as close to the measured point as possible.

This method is easy to operate, but the effect of measurement is the worst. In each method, the measuring end of the thermocouple should be as close to the measured point as possible, so as to get a more real measurement result.
