Hello all,
 
We have a customer with a unique application.  Part of a 6 layer FR4 PCB
will be immersed in a chemical flow.  They conducted tests using a board
with routed edges and were successful.  
 
This application would work better if we could use V-scored boards.  The
boards would be separated with a "pizza cutter" style de-paneler. The
total edge length in contact with the chemical would be almost 18".  
 
Does anyone have any information to suggest the V-score would perform
worse than a routed edge when it came to chemical intrusion.
Unfortunately I do not know what the chemical is so I am unable to tell
you what it is.
 
Thanks for any help you can give.
