Hi Technetters,
       We are researching moving away from plugging our vias with solder
     mask (problems and reliability issues) and plugging with solder thru
     the wave solder process.
     I have read all of the archives, and printed a major novels worth
     (thanx for past info group, those archives are a wealth!!) bit one
     item is still missing I hope you can respond with info on:

     ASSY: Do you have problems with, or design guidelines that address,
     the solder filled vias under components, or is this even an issue?

     FAB: How do most of your customers address this?

     Please, deluge me with your wisdoms, responses and help on this issue.
     Thanx in advance group.
