gEDA-user: soldermask clearance

[gene glick <carzrgr8@xxxxxxxxxxxxx>]

What's the right amount of clearance?  Seems like .003" is good, but I 
don't know.  A google search found one article that said for fine 
pitched parts, it's better to have the entire row blocked.  That is, 
instead of individual clearances around each pad, the soldermask exposes 
the entire row at once.  They claim the very thin webs in between pads 
are too thin to cure correctly, and will smudge later onto the pads.

Anybody experience this sort of thing?

If there's no soldermask in between pads, isn't is more likely to get a 
solder bridge?

thanks

gene
