The reflow oven is used to bake our boards and solder them. In the past, we have had issues with the solder paste not melting fully and thus not creating a good joint. We have also had issues with uneven heating, and soldering multiple boards at once. We would love to be able to fix these issues with the oven instead of doing all the manual rework that we have had to do in the past.

QS-5100 Details
- Features
- One sided infrared heating
- Issues
- Uneven temperature distribution causing uneven heating
- and inconsistent solder joint across a board
- Not CSA certified
Where is the sensor that the oven uses to measure the temp? - it would be great to know to compare accuracy of the results.
General Reflow Tips
- Preheat the board to bring the board up to temp to reduce the chance of cold solder joints if the whole joint is not up to temp
- Don't make the preheat period too long or else all of the flux will dry out
- Every component usually has a recommended reflow profile in the datasheet (or at least max temps), as well as the solder paste
- We will follow the recommendation for the solder paste, as this
- etc.

Can be used with the orange Keysight multimeter (I forget the model number right now) and the Keysight app to export the data. We want to export a CSV if we can in order to easily graph it with excel of python.
It would be great if we could also map a temperature distribution of the PCBs and the oven as well.
