Measuring Pcb Temperature

Click For Summary

Measuring the temperature of a PCB via presents challenges due to its small size, with thermocouples potentially affecting readings by drawing heat away. Thermal cameras like the FLIR ONE have been suggested, but their effectiveness is limited by the size of the via compared to the camera's measurement spot. Low-mass thermocouples and techniques to capture contact transients may provide more accurate readings by measuring temperature at the moment of contact. Additionally, monitoring the voltage drop across the via while measuring current can help infer temperature changes based on resistance. Overall, combining these methods may yield useful data for analyzing localized hotspots and temperature variations in the via.

With the wonders of Internet cookies and Amazon and Facebook, an advertisement for this just showed up in my Facebook feed...

They are so nice with you. Guess what started to come up regularly (without any previous search) when I passed forty :doh:

Yeah I've noticed that industrial is always more neatly done.

It's not about industry. Any tech who thinks he will have a second time with that panel will do it like this.
Well, it's a bit contradictory since because they do it like this it's unlikely to have a second time within a decade or so...
