Hi all,

I could have sworn that I read somewhere in EN 61010-1 that creepage distances 
on internal layers of "void free" PCB boards were reduced from the normal 
distances.   For the life of me, I can't find the statement.  

I also seem to remember that there was no hard, fast number given.

So, my question is three fold.

1.  Where is this statement?

2.  Is it true that the creepage is reduced for interal layers (as compared to 
surface layers)?

3.  If it is reduced, where do I find a table, or some actual values to use?

As always, the wisdom of the group members is appreciated.

Thanks,
