one of my customer areworried about the flux risidue in the blind vias, or if the plug the vias and there is air trapped the plug will blow during our process. Appreciate for your response

Russ We agree with your comments on plugging from one side only. But... We believe that it IS possible to trap process chemicals [technically, not flux] in a blind [or any other] via. This can be done by plating the via closed, rather than pluggi

Consider a 6 layer board. The Through via gets drilled from top layer to bottom layer. All 6 layers has the hole drilled in it. A blind via is a via that does not got through the entire 6 layers. It would go from layer 1 to layer 2. or layer 6 to lay
