After creating the first few temperature sensors the PCB has been updated. It’s smaller now. Soldering went smoothly. The fact that the PCBs came in groups of 6 made applying the solder paste much faster. After soldering the PCBs did not look very nice. But after measuring all were as expected and the question is whether to clean the PCBs would help to make sure the the remaining dirt does not cause long term problems. Unfortunately an off by one issue appeared.
