No.  The best way I have heard to do this is to overdrill the blind
vias on the top and bottom layers, then wire jumper to the inner
layers.  Standard vias do not connect the two middle layers, or to the
two middle layers, but only top to bottom.  This avoids the plated
through holes.

I have yet to design and implement a board like this, though.  Still
theory.

The same thing with connecting to layer 2 of a four layer PCB. The top and bottom layers are straight forward. A 16 layer board is built one layer at a time (etching)? I have never worked with anythng other than 2 layer PCBs as far as installing/removing components. Modern computers use multilayer PCBs. Any guidance would be appreciated. TIA  Charles  AE5EW
