Subject: Plastic Encapsulated Microcircuits and Semiconductors
I am trying to obtain a copy of a document produced by EIA/G12 called "SSB-1, Guidelines for using Plastic Encapsulated Microcircuits and Semiconductors in Military, Aerospace and other rugged applications". Can anybody provide guidance about getting a free copy? I have tried JEDEC and RAC, no luck.

Subject: Long Term reliability Effects of "no clean" flux.
I have discovered that certain assemblies being used in a system we are designing contain "no-clean" flux. Do you have any information on the long term reliability effects of this type of flux. The items in our system containing this type of flux cannot be cleaned (for reasins I am not too sure about). The environment the items will be used in is a naval sheltered one.
