hello,

are there any rules (of thumb or otherwise) for placing components when
doing a hasl/selective tin plating.   in our case, we have a board that is
mostly hasl finish.  then we have some buss bar pads that are selective
white tin plated.  is there a rule of thumb as to how close a component can
be place to the pad that is selective white tin plated or is this entirely
process/fabricator dependent?  i'm assuming here that the fabricator must
some how tape over the tinned pad to apply the hasl finish.

thanks,
