Abstract:
1. A coaxial via structure in an electronic device carrier adapted to connect power/ground voltage comprising: a first generally round conductive track of a first conductive layer on a first surface of a dielectric core a second generally round conductive track of a second conductive layer in a central portion of said dielectric core, and a third generally round conductive track of a third conductive layer, said conductive layers being separated by dielectric layers; a coaxial via structure having at least two first conductive vias for conducting voltage only connected to said first and second conductive tracks; at least two second conductive vias for conducting voltage only connected to said second and third conductive tracks; a fourth generally round conductive track of a fourth conductive layer surrounding and on the same level as said first conductive layer; a fifth generally round conductive track of a fifth conductive layer surrounding and on the same level as said second conductive layer; a sixth generally round conductive track of a sixth conductive layer surrounding and on the same level as said third conductive layer; at least two third conductive vias for conducting voltage only connected to said fourth and fifth conductive tracks; and at least two fourth conductive vias conducting voltage only connected to said fifth and sixth conductive tracks.
