  We have several boards that due to their electrical performance
  cannot tolerate soldermasking.
   They are currently tin/lead plated but our vendors are saying they only
  want to
   do SMOBC boards.  What are my alternatives?   Are there any mask
  materials that are recommended for extremely low level signals?

  Thanks in advance,
  Doug Bossert
