I know nothing about them other then they exist and they can pop off if you're not careful with them ...
Yeah I looked already. The 8-pin clips is the most common as I have one of those. I have never seen on for a 44 pin chip before and I looked all over. Even this small board was hard to find. Actually I am using a board for the P12 chip, which I had to use hot air to put it on. Plus this little board was only $5.

It's all about required pin layout, get creative with multiple clips, depending on required pin layout.
I'm not a chip lifter, though I've never used hot air, I've done a few through holes with iron and wick (and air hose), it's a pain in the well you know what!
Can't wait to try my new hot air out on my cold jointed MDI clone, a P12 got in my way though ...

I can't imagine lifting a chip without hot air. Would be EXTREMELY easy to burn a circuit board with an iron. If you have something laying around with some sort of chip with a bunch of pins, try using your new hot air and try lifting it. I always try to use something thin to wedge very lightly, and tilt one side of the chip gently while applying hot air. Once the one side lifts, I take the hot air off and wat about 5 seconds for that side of the chip and board to cool, then lift the other side with hot air. It literally takes less than a minute to lift these chips. You are going to love that thing.

the "ChipQuik Alloy for SMD Removal" works well with just a standard soldering iron. You bridge all the pins with a bit of this stuff which looks like solder and its a different metal and lowers the melting point of the solder on the board. then you can drag the iron across the pins a medium speed on one side, then the other, then the first, while pushing the whole chip gently from the end and it doesnt take much to lift the whole thing. you can also re-solder it pretty easily, the same process but lift off excess solder with some solderwick. Ive never used the hot air tools but they seem to work fine too and is probably better if your serious and have more than a small number to do. Plenty of example videos on youtube, here is one

I have pulled quite a few of the flip-chips on this board and examined them under my microscope. I am in the process of trying to ID them. Hopefully if we learn it's hardware and learn it's similarities with other GM PCM hardware, it will be easier to crack.

I know it's been a few weeks since I have uploaded anything else on the P10, but good news... The circuit board I needed to solder the flash chip to has arrived. I soldered it on tonight and already pulled the contents of the chip. Hopefully someone can pull this bin apart and find some info that will help us test the P10 with PCM Hammer and Universal Patcher.
