Another approach with which I've had success is to use something like PCBite's probes [1] to stab the little bits of solder sticking out the sides of the WSON package. PCBite's probes are excellent; they're sharp enough bite into the solder and hold themselves in place. (Those stalks aren't stiff; they support themselves by digging in.) PCBite is an all-around great product and definitely worth the somewhat-steep-for-a-hobbyist price tag, in my opinion.
Very cool. Seeing as those probes are far more general hardware and offer extra capabilities which could be really nice to have around, that's an attractive option. Strong contender for best approach to date for my case (and just overall valuable information).
Thank you for sharing your experience!
