Does anyone in Montreal have a hot air rework station and could help me remove two DAC IC's from a proto board I have? I've got a short somewhere I just CANT find for the life of me. If I have to I'll even ship it to someone whose willing to do the job.
Thanks guys!!
Thanks guys!!
its for SMD work, blows hot air on the pins to melt to solder so you can remove the IC. Google it 😉
You should state the part outline of the ICs to be removed. Those who have the equipment may not have the right tool. E
I need a BB PCM2707 and PCM1798 removed from this board so I can find the short and put them back correctly.
Are you sure the short isn't U9?
If you just need to remove the two ICs and can't find someone with a hot air station, you can try this kludge. Take some thick paper towel and fold it over a few times so that there's a couple layers. Cut a square hole in the middle a little bigger than the IC, and then tape the paper towel to the PCB using kapton tape. Set the PCB down, heat the IC with a heat gun, and lift it when the solder melts.
It's not the prettiest way and it takes longer to set up than using a real work station, but I find I can consistently remove TQFPs without disturbing the other chips around them.

thanks to fastvideo its all up and running! and thanks for the tip Mr Teal, maybe I should invest in a rework station if I'm to keep this up.....
