BGA Rework Station Profile - Advanced

Some things I do differently but this is the best tutorial I have ever seen. (The Basics) viewtopic.php?f=51&t=2184&start=10

Altec PC410 gives you different temperature reading, It is because the wiring from the connector to the controller.
When the controller heats up it slides also, so it is important to use external TC meter.
When you have timed how long it takes to preheat using bottom IR only to the temp you are aiming at.
Then you use the altec pc410 sr232 and the software to look how good your temperature curve is.

If the curve looks bad you can smooth it by using the lower hotair.
You can start using top ir when you hit 160C top of the pcb this smooth temperatures.

But the key thing that you forgot to tell is that the controllers TC are in different places.
Bottom heater IR temperature is controlled over the IR plates this is why you need to set it higher.
Because it is not the PCB temperature it is reflective heat/radiation from the ir elements.
When the controlling is done like this you also need to tweak PID setting in the temp area where you like to rework.
This is easy to do make the PID output led blink constantly when you are in the set temp.
It does not matter if the temp slides as long you have constant output.

Top ir is controlled by your TC touching the PCB so this is the real “chip” temperature.
So this is why you need to use ramp 1 that you don’t burn the chip keeping the radiation on too long.

The bottom Hotair is controlled from air flow so if you want same temperature what is in your preheter is giving you measure temperature
from bottom of the pcb above the ir plates and same time under the chip where is the hot air nozzle. Using two TC sensors.

When you set bottom hot air to 222C it is actually 222C in the bottom of the pcb. It depends how close your nozzle is.
When preheating the pcb keep in mind that the bottom nozzle is blowing could air in the bottom, if it is set to zero... could air hmmm 30c air haha desert man.

But really good basic information and I know if beginners do like you
they will succeed at the first try. Great beginners tutorial M8 10+

I registered here because of this vid. Now i like to see advanced profiling vid....

I have set my PID to 230C and you can see in my vids how it works 230C and 220C. Slides more in 220C...

On most 3 zone hot air stations the set temp for your top and/or bottom hot air nozzle gives the AIR TEMP.
NOT the PCB temp.

That is also the reason you see rework temps of up to 265C with HA, as it is the air temp, not the chip.

Or, for same reason, with IR most use 225-230 as max setting.
As here you read pcb/chip temp.

Need to realise that, especially with IR.

How to Calibrate bottom and top Hot Air that you can do many runs no need to wait the room temps.

Hi, has anybody set up a profile on a honton r392?
I'm trying to reach a consistent topside board temp of 160C, I've set the ir plates at 230C, upper hr 3/0/600 end and lower hr 3/230/600. The problem is
the topside board temp is only reaching 130C-140 max even after 15mins. If I increase ir plates to 300C and lower hr to 260 it still only gets to 150 in
15mins. What am I doing wrong?

You need to start a new Thread TBH.. im sure the BGA police will correct us here.. :rolleyes: :rolleyes:
we also need to have your tc placement etc,
But any how , check here , this will sort you out, KINDA.
viewforum.php?f=37

these dont include bottom HR / 3 stage.. if i recall ;) ;)
