Here's a little tip from back in the PS2 24 wire or whatever soldering days...
When attempting to solder any sort of pins that are really close together, such as with the 79 pass key socket thing, if you want to make ABSOLUTELY certain that you don't bridge them, just hold (or have someone else hold for you) a razorblade inbetween the two pins while you solder one side. Not only is it a seperator, but it acts like a heat sink as well.
Or you can do like the procedure floating around with the soldering braid. I just don't like the idea of putting solder over ALL the pins, and then cleaning up the excess with a braid. That's probably just me being stupid, as it DOES appear to be a bit less time consuming.
Lord knows, if I had had some soldering braid at the time (or at least some patience to wait until I had it) my first PS2 chip install would have worked flawlessly. As it was, I did it PERFECTLY, but forgot to hook up the DVD drive ribbon, assumed it must have been one of my solder points, went back and managed to bridge a bunch of pins on the microprocesser. This was when braid would have helped me; you can MAD LIB up the rest of the story.
What I don't know is why they don't just put some solder on the bottom of the cable plug leads, some sticky tape to attach the thing, and ship it out like that. Then you'd just have to affix it, line up and apply heat.
OH well, probably because it'd cost too much.
