Pardon if this is discussed to death- then I would need some hints to the threads...
Situation: Old equipment, some IC is directly soldered to the PCB, with more than 8 pins, and it eventually is gone bad.
Now, without fancy equipment for desoldering and cleaning up the place where it sits, options are limited. Especially when considering that maybe with re-soldering a good replacement might put some real heat on the neighbouring components...
So the thought would be, to de-solder the old IC, and solder in a nice IC socket where to place the new IC.
In my recent case, I still am stuck a bit with a linear power supply and a LM224N, as central quad-opamp.
Questions:
- which possible drawbacks could i have in this concrete scenario? Bad contacts in the socket or some higher resistance on the contacts of the socket?
- What about effects of HF etc.? Theoretically a linear PSU should work on quite low frequencies, so the enhanced distance to the PCB should not matter
