Ken, thanks for your answer, it is much better presented than what I was fed by our qc. By "calibrating TCs" I meant the readings the controller is displaying on the screen. So that would be the converter that we would check and calibrate. Thank you

Hi Charly, For batch ovens there is no discussion. For inline loading interval depends on the oven you use, the amount of heat the PCB takes out of the zone and the capability of the oven to get it back in. The approximate time for the PCB to stay i

Charley: As Wolfgang says, you're unlikely to be able to put enough (average) boards in a modern reflow oven to be able to thermally load the machine. Ta Dave F

All i used to do was blow them with an airline to remove the excess moisture then bake them for 15/20 min at 100' in an oven and that seems to work fine, i did get the info from a 4 stage cleaning guide for the actual cleaning solution we used but it

what type of oven do you have . How many zones? and what are the board attributes sizes. We run alot of doublesided reflow with BGA. maybe I can help

Charley, Though my reply is quite late, it might be a good info for you and i hope that this info could help or could provide you some views. Some companies practice at least 1 board gap, which means the length of the pcb you are currently loading,

I agree with Russ. Hotplates, toasters, etc.. may be cheaper than a smaller oven, but it will really pay off in the long run. Plus, your process control will be much easier to control.

call me picky but doesn't hydrogen combust? maybe soemthing you could do is look at your process and your products and decide if you actually need to run in N2. Yes ok I can hear the crys now but seriously, for the vast majority of things if you have

90% of the battle with thermal profiling is your thermocouple attachment. That is Process Engineering 101. It's just like painting your house. The masking and prep work will make or break the end result. KIC did a DoE on which thermocouple attach
