With a sufficiently-narrow soldering tip and a sufficiently-steady hand, sure ;)
Would you trust a paper that reported results based off of experiments involving "sufficiently-narrow soldering tip and a sufficiently-steady hand"?
Sure, why not? Thats what a lot of real experiments involve anyway, I don't think anything is gained by obfuscating actual methods because they aren't scientistic enough.
Honestly, that is what I was expecting given the title of the paper. That or a partial reverse-engineering and emulation of an SSD controller firmware.
