Hi Wesley, This is what I would do, if I understand what you described...
Make a physical clearance in the inner plane where you put the via so it will not connect... If you are using power/gnd planes and not polygon fills then you need to just put a fill or pad in the area on the negative layer where the via is, and make it connected to no net... It will plot reversed as a hole in the plane... the via will not be close enough to the internal copper to make the connection. If you are using Polygon fills for planes, put a keepout area around the via and regenerate the polygon fill. Hope that helps... Bill Brooks PCB Design Engineer , C.I.D.

TI do not want to connect it to the inner Vcc plane as the decoupling caps are on the secondary side of the pcb and I want the voltage to see them before the leg of the IC. I tried making a pad and using the padstack to not connect to the middle layers but was not sucessful. Any help would be welcome. Thank You in advance.
