The most precise Way to attach Thermocouples
For reflow temperature profiling with thermocouples, the attachement to devices and board is critical for a repeatable and precise measurement. Welding directly onto devices and the board is the most precise method to achieve a temperature delta of <1K.
How to attach a thermocouples
Temperature profiling for all kind of soldering process is necessary to develop a reliable process that results in good soldering quality. There are different ways to attach thermocouples onto the board an devices.
