I usually check with ohmmeter in areas where i expect possible problems,  
e.g. tight spacing or very narrow tracks. (sometimes after soldering,  
sometimes before, depending on situation).
I use toner transfer which inherently prevents breaks, but it can  
sometimes be a problem with too narrow spacing.
