Ken, I tried it for removal of power MOS-FETs (bare die, approx 0.300"square) from ceramic substrates without a great deal of success. This was most likely due to having very little exposed (initial attachment) solder (Sn 63 or Sn 10) exposed for their low-melt solder to alloy with. For this application it was also not very user friendly for keeping the nearby conductives (10 mil line and space) free of rework solder. I also had some initial reservation about residual low-temp solder remaining to corrupt the subsequent joint - but I never got that far. I am sure it would work quite well for most SMD's with relatively large exposed solder joints, etc. I would at least do some DSC's on resulting joints to assure myself that the melting point had not changed too much. What this does to the microstructure and resulting reliability, I can not answer. Possibly some of the real solder guru's out there have comments.
