Gary, thanks, I am sure most of us in this forum understand the proper
packaging. DRS's problem is that the supplier of the assembly failed to
sue proper packaging such as using a Static Dissipative bag first, then
an antistatic materials (bubble wrap)and then into a ESD protective
cardboard container. The results was possibly under covering uncured AR
conformal coating at shipment stage. We are just trying to determine
root cause and how to handle those assemblies already having the bubble
wrap impression. Again I thank all for their inputs and plan to provide
the rest of the story. Sincerely, Jon

AR Conformal Coating is Acrylic Resin and has nothing to do with ESD
protection.  The boards
 must be first placed in approved ESD bags prior to any other packaging
material.
