Werner is the master (but I am sure he is older), I am just beginning to
learn.

Best regards

  Werner,

  I'm beginning to think you and Lee are both "Good-Old-Boys" who
learned
  a valuable lesson working at Bell labs; consulting is much easier with
  those who have problems than those who don't.  I don't think that
  continuously finding customers that have ENIG problems makes you and
Lee
  the most unlucky individual on the planet.  Actually you may be among
  the most lucky individuals who have business come looking for you
rather
  than you looking for business.


  Regards,
  George

  Hi Joel,
  I do agree with Lee Parker. I am glad you had no problems with
  ENIG--many of my cients were not this lucky.

     Lee,
  Good input that I agree with. However, I was wondering if you could
  further discuss the "flash" vs. "ENIG" issue. I have been using ENIG
on
  my Pb-free assemblies for about 7 years with very little problems. If
I
  am missing something further education would be extremely helpful.
  Thanks

  After reflowing a soldered surface, you will form a meniscus which
will
  interfere with SMT component placement. To avoid the problem I suggest
a
  flat metal finish such as immersion silver or flash gold (not ENIG)

  Best regards

                Hi technetters:
                Is there a fine pitch limit  to the use of HASL board
  plating
    finish due to its variation in thickness?  Does selective solder
strip
    and reflow plating, SSSR, have a significant advantage over HASL?
Any
    comments relating to platting finish would be greatly appreciated. I
    thank you for your comments.
