Yes. Filter it with coffee paper filters from time to time.

Don't waste your time and money complicating a process that works so easily.

This works really well

The thermocouple should be attached to the board, not put in the boiling liquid; it's physically impossible for it to be anything other than 230°C, no information is gained.

Thanks for the help, will run the lot through some filter paper and see if that helps. I just ran another batch, and getting some tombstoning, so probably will upgrade to a PID controller at some point soon.

RE the thermocouples, the one above the board is there so that i can be sure that the whole board has reached thermal equilibrium before this sensor hits 230. Regarding the other one, I start from cold with the board in place, so having a sensor that lets me know how long until the vapour cloud forms is useful as i am operating this manually.
