Vladimir, Since no real "plating person" has yet replied, I will toss out what meager info I have. My notes were that <1% B yielded readily solderable and wedge bondable surfaces where as baths of 2-3% B were noticeably hard (but no notation on wirebondability or solderability). Some baths can be 5-6% B, but have no specific comments of them either. Should you get any further comments, I am very interested in them as well. Sorry, but I can not define what 'normal' is. Presume it is specific to the plating house and what they are currently running.

Thanks a lot in advance.
