BJ-ENG,
If there is any moisture present around the die, then any application of voltage will cause an electrolyses effect and irreversible damage. So, If there is any suspicion that water has penetrated, the most like course of action is for a trip back to the manufacturer for the top of the package to be removed under controlled conditions and a session of drying and cleaning of corrosive deposits in the hope that maybe something useful can be recovered.
Considering the careful way the whole issue is being handled we could expect they would avoid any risk in loosing the valuable information we hope is still present at both CSMUīs.
The non tangible (and tangible) value of the info after itīs analysis is "immensurable".
