I decided to try to get the AD9865 off the Devolo board and try replace it. This is a 64 pin device in a 9mm square package with a thermal pad underneath. Damn thing won't shift! I made heat guide shaped like a kind of inverted pyramid with the point cut off, out of a bit of baked bean can, so the hollow point fits over the IC, directed the heat gun into the wide opening, watched a whole lot of nothing happening as I blasted hot air in. Tried making nail holes around the bit that fits over the IC, tried again, still no joy.
Tried without the heat-guide, all I managed to do was dislodge a capacitor, took me half an hour to get the damn thing back. Grrrrr.
So, any suggestions how to tackle this? A smd re-work station is out of the question! I need a process I can repeat to solder the new chip in - I do have some solder paste I can use for that.
Thanks
