Dear Collogues:
=20
This application if for the Long Term storage of partially assembled
Board to 25 years
=20
The final CCA is a backpanel for an avionics application. There are
some SMRs, SMCs, and a few other parts that will be soldered to the
board. These parts will be soldered to the board BEFORE it goes into to
storage. Connectors will be pressed into the board and then the board
will be conformal-coated AFTER storage. The board finish is HASL. The
board material is polyimide-glass.
=20
Concerns are about connector and PCB quality after this time.=20
Questions are:
* Quality Methods
* Materials
* Environment of storage, packaging, etc.
* Board cleanliness
* Reliability of connector
* Does anyone have any direct experience for storage this long?
