     Also, Can sombody explain me if there is a process to cover with Soldermask
     tented via holes without plug it with soldermask?

     I don't have the IPC spec's. What is the requirement for this matter? It is
     allowed to plug with soldermask tented via holes?

     Thanks for your responses,  Mauricio

We have 0.016 vias and are considering tenting vias both sides with
soldermask. What is the recommended method for doing this and getting
complete tenting without breaks or bulging out?

We do not want dry film on the entire board.

Thanks......Ron
