What are the problems with running the soldermask to the edge of the printed 
wiring board and non-plated holes?  We have been keeping it away by 50 mils 
but you see alot of commercial boards with it to the edge.

Does it depend on board material?  Does it depend on whether it is 
commercial versus military?  Does it depend on dry versus liquid soldermask?

Any ideas would be appreciated.
