Ioan,
In addition to the other good answers posted, you also need to keep the 
exotherms of the potting material in mind.  Some potting materials get 
very hot when reacting.  The cooler potting materials have correspondingly 
longer cure times. 

For both materials, you also need to keep in mind the CTE effects of the 
materials under components.

Dear Technos,

what would be the Design for Assembly concerns related to products that

Thanks,
