you want a gradual 1c/sec temp increase until you reach target topside temp, thats it. running profiles lower side is a waste of time.

lmao youll need a higher lower temp than 175 to achieve a topside temp of 175, basically set the lower plates to 250 and run a profile of this:

0.00/0/600
-0.01/0/0

this will make the pc410 not output anything from the top heater for 10 minutes, so only the lower controller is working.

then record your topside temps at minute intervals and find the best time to get a consistent topside temp, then start to program the top heater.

lol i dont design the tc location mate so couldnt tell you.

tbh theres not much point measuring the lower side as our target is to get topside to 217, as long as the preheat is even its irrelevant where the lower tc is located as measuring the air temp, bottom of board or lower plates will still result in the same outcome.

like i said the most important measurement is the topside temp :)

[quote="brett1"]this is curve from hr6000[/quote]
Brett, can you tell me what the red line is. I set up the profile as you had set but my red line doesn't move at all. I think it was at 41 the whole process. Wondering if the HR6000 I have is not working right. It didn't budge the chip on the motherboard I was testing. Any help would be appreciated.

@crossleymarko - Locate the controller's TC anywhere under the board. I wouldn't recommend on top of the board because the
bottom of the board could get too hot depending on how quickly your bottom heat elements heat up. Bottom of the board
could get 250C for all you know before the the TC on top of board can tell the controller to back off. Have heard not to let
bottom of MB go much over 200C on bottom of MB. TC on element will reduce overshoot but temp of board could wobble a little.
Putting TC on bottom of board is more precise but could slightly overshoot. I put mine on bottom and don't have an overshoot
problem though. I don't think it matters to overshoot at that temp though. It will stabilize. Overshoot is an issue more with your
top heat at reflow temp.

If you look at the HR6000 curve graph posted by Brett1 on the first page of this thread, you can see that the green line is the TC
in the HR nozzle and the red line is a TC plugged into the side of the machine and placed by the bga chip.
