Good luck Pete.

Regarding conductive glues. Most of these are filled with silver so 
you'd get a nice galvanic cell set up. You would need to be very careful 
with glue selection. You wouldn't want to recall 3 million circuits once 
you discovered they'd started corroding in the field...

Regards,
