Impedance matched via connections in a printed circuit board

A printed circuit board electrical connection assembly comprising:

• a printed circuit board (PCB) having a top surface, a bottom surface, and an interior therebetween, wherein said PCB includes a signal line and a ground or zero potential contact or line;
• a via insertable within or formed within said PCB, said via having a via body defining an inside wall, an outside wall, a top surface, and a bottom surface, wherein the inside wall forms a via center through-hole, and wherein said via body includes an aperture or slot adjacent either the via body top surface or via body bottom surface, or said via body includes at least two apertures or slots, wherein a first aperture is adjacent the via body top surface and a second aperture is adjacent the via body bottom surface, wherein said via body is conductive for transmitting electrical signals or for providing a ground or zero potential, wherein said via body extends into said PCB interior, and wherein said via body is cylindrical having an outer diameter, and includes a ring on said via body top or bottom surface, or both said top and bottom surface, said ring having an outer diameter greater than said via cylindrical body outer diameter, such that said ring extends beyond said via cylindrical body in a radial direction, and wherein said ring includes said via body aperture or slot extending therethrough such that said ring aperture or slot aligned with said via body aperture or slot;
• and
• a cylindrical dielectric component having a body defining a dielectric component inside wall, an outside wall, a top surface, and a bottom surface, said dielectric component body sized for placement within said via body center through-hole, said dielectric component body including a center through-hole coaxial with said via center through-hole, and wherein said dielectric component body includes an aperture or slot adjacent either the dielectric component top surface or dielectric component bottom surface, or said dielectric component body includes at least two apertures, wherein a first dielectric component aperture is adjacent the dielectric component top surface and a second dielectric component aperture is adjacent the dielectric component bottom surface, and wherein said dielectric component apertures align with said via body apertures when said cylindrical dielectric component is slidably inserted within said via body center through-hole;
• and
• a conductive trace and/or solder bridge formed on or within said PCB and traversing through said dielectric component aperture or slot and through said via body aperture or slot to said dielectric component center through-hole without making electrical contact with said via body.
