as long as you get some tin foil and make a cut it out so just the scsi chip gets the heat,

you can use a 22 dollar heat gun,

I just bought one and i love it. mcdermd uses his sometimes

You want to use some long electronics tweezers to pick up the chip.

use an iron to clean up the pads (if needed) , lay some flux down, then set the chip on there and melt it in.

I do have a extra scsi chip, it's on that board I got from CC-333

PS:

Last night I removed the FPU,(from CC_333's parts SE/30 Board) The CPU and the CPU socket, A ram Slot yes the heat gun rocks!

I got lazy and didn't mask the Battery Holder (when removing the FPU)… and it partially melted (so ya gotta be a little careful that air is super heated it)

I got my mouse pad a couple times there is now a couple big black spots. haha

I use 2 dead LC PSU's to raise the board off my desk/mouse pads.
