List,
We are considering changing our vias from plated holes with a tolerance
of +/-.003 to +.000 -(hole diameter) to basically fill the vias with
plating. The reason for this is due the the nature of our products. Does
anybody know of any down side to plating vias closed? The typical finish
is HASL on our boards and we have been tenting the vias.
Our goal is to make the via connection as robust as possible. We were
even considering using z-wires in all vias but plating them shut seems
much less labor intensive.
Thanks,
