I find that what happens is: nothing...squeeze harder...nothing...squeeze harder...hooks rip a chunk out of the bottom of the PLCC, leap out and score a nice deep scratch across the top of the IC for good measure.

Hm, I think these extractors are not too bad, at least for PLCC44, and if you don’t have to pull lots of ICs per day. Of course there are sockets that grip stronger than others, then it might become a problem.

Maybe these extractors are better, never tried one. Not cheap, though.

> I've got a faulty Lexicon PCM80 here where I would really like to try changing the main CPU, but it is a 68-pin socketed PLCC and I can't get it out. I've tried, and the results were as described above! As far as I can see, you just need to treat socketed PLCCs as if they are soldered in, and desolder the socket with the IC still in it.

How do you unsolder a PLCC socket with the IC still in it? Hot air?
Or is that a PLCC socket with through-hole pins?
