[DIY] BGA rework station

Postby egberttheone » Sat Aug 24, 2013 3:39 pm

I'm building a small PID controller that is controlled from a laptop application.
See screen shot attached.

It will have 2 TC inputs for accurate temperature measurement.
2 phase synchronized outputs to control the heat from the nozzle and the preheat er.
2 PWM controlled outputs 1 for 858 Hot Air Wand and 1 for cooling fan.

Ok, your progress so far look PIMP dude! I have just a very tiny bit of experience designing a controller. Anyways, you 'may' want to change the variables for Kp, Ki, and Kd to double so you can tune it more closely. My setup is all whole numbers as well. I totally lost all interest in finishing my machine now. Actually, I lost interest in EVERYTHING. I have problems i think lol. Good job so far and please post more. Maybe kick my ass into gear over here!

EDIT:Your way is very smart. :) Having the control code on the PC does seem like an easier/simpler solution. I was coding mine for no PC use since I never connect pc to my machine anyways. Its awesome though. If you would like to chat at all please let me know.

It’s cool to make a standalone unit but it requires a lot of work to do the firmware.
Using application that runs on a PC is easier to control, as it has the UI already made.
I have finished the PCB design and have changed some things:
First idea:
It will have 2 TC inputs for accurate temperature measurement.
2 phase synchronized outputs to control the heat from the nozzle and the preheat er.
2 PWM controlled outputs 1 for 858 Hot Air Wand and 1 for cooling fan.

Now:
2 TC inputs.
1 USB port for control.
3 phase synchronized outputs to control the heat from the nozzle and the preheater and cooling fan.
1 PWM controlled output for a hot air (blower) wand.

The software uses double values, it should be quite accurate

PCB assembled.
firmware done, software needs to be tested.

I'm now working on the rework jig setup. 8-)

PCB is pretty messy had to get some design flaws fixed.
Hardware and firmware is tested and is working.
