yeah, in my application, the high barrier capacitance in the DCDC caused the micro to lock up, but the fets were still fine. it was really weird, but using the powerex dcdc solved it.
would you be able to rig up some way to clamp the mosfets to the bus bar for a quick test instead of using solder? That might be a quick way to see if the soldering was the problem. Just add a little thermal grease and maybe just weigh them down with something heavy. You probably won't be able to go to as high of currents, but if it still has problems, then that rules out the soldering...
