Jbillk, don't throw them to the garbage, find someone near you that have soldering skills using hot air guns, buy yourself a good soldering paste and bring one hashing board and ask the tech resold the chips and most of the components on the hashing board.

here is a top notch soldering paste

Problem is that all the boards look ok, it would be like finding a needle in a haystack finding the bad chips. The log shows 0 chips detected on all 3 boards, so i have no idea witch ones need to be re-soldered.

I also tried blasting the boards with hot air gun, no results.

Not sure if reflow oven at higher temperature will work (already tried 10 min @ 200 deg c). Really have nothing to lose, i'm just experimenting at this point.
