I've replaced SOIC-8 SPI chips with just a 15W soldering iron - the biggest issue is ensuring that the new chip has same voltage requirements as the old chip / board is providing.  Many of the 8MB parts are 3.3v and most of the 16MB ones I've seen (at least in Chromebooks) are 1.8v

A friend of mine wants to do some SPI rework. He wants a  16M part in his chromebook, not 8M. (hmm, so do I). Given the huge expertise of this group, I wonder if you have advice about equipment he should get.

Soldering irons? hot air guns? magic wands? 

thanks
