hello,

1.  are there recommended stay out area around a pad(s) that need to be
selectively white tin plated.  i.e.  for the taping process when using a
hasl/selective white tin process?

2.  is immersion tin recommended for buss bar applications?  what are the
pros and cons

3.  a vendor has indicated that white tin is not a recommended process by
the ipc council???  i have not seen this in technet while searching in white
tin.....   is there somewhere else i should look??

4.  is it not recommended to do a hasl/selective tin process???

thanks,
