I want to replace the 32MB RAM on an 1998 VAIO 505FX with 64MB.
I'm planning to take off the chips with my hot air station.
What's the best way to solder the new chips on though? The space between the ICs is so narrow and the solder pads are barely longer, if at all, than the IC's legs.
Recommendations?

I'd use a regular soldering iron with a narrow beveled tip and plenty of no-wash tacky flux, despite the crampedness. Make sure you have a copper braid available too.

Since you have a hot air station, using it and tin paste might be an easier option if you have some previous experience with that method. If you aren't spot on with the amount of paste to use, it will probably end up in a mess though.

Also use kapton tape if you are planning to use hot air.
