Removing a ULA
Removing a ULA
This is not the way to remove a defective ULA. There's no room. Aargh... I'll try again tomorrow.
Re: Removing a ULA
Oh my... where you trying the hammer method
Well now that's happened i would use a small.pair of side cutters to cut each pin remove the bulk of the chip and the one at a time remove each pin with tweezers and soldering iron, clean the up the pads and your good to go.

Re: Removing a ULA
I'm trying to remove it but I don't have a cutter that's small enough. And I gave up desoldering.
To put it simple: I don't have the tools to remove an IC.

Re: Removing a ULA
Well - this is not a high quality tool like side cutters from Knipex (I prefer) but sufficient for this job.

Once again Dremel is your friend.
Re: Removing a ULA
Finally! The tinsucker was great help. I hope I didn't cut some traces during the battle.
Re: Removing a ULA
Well - I would use a socket now rather than soldering the next ULA again directly.
Re: Removing a ULA
That's the plan.
Is there an issue 3 pcb layout somewhere?
I think I have bruised a connection. It would be easier to find that with a pcb layout than using a schematic.

Re: Removing a ULA
Is the bruised connection visible with the ULA in place?
I have an early Rev 3 board with the older ULA in it. Happy to take pics if you need them...
