Hey Zhenyu, 

My bad - I just assumed it'd be packaged or epoxy encapsulated. 

Flemming - I followed up with John Hammond - We don't have a thermal imaging 
camera in the electronics group, but we've borrowed one from ATLAS in the 
past, if you wanted to see about that avenue. 

Best, 

Mike

Hi Mike,

The APV chips we use are bare dies, not packaged. We can't tape anything to 
them.
