Abstract
A circuit board construction which reduces unwanted electrical effects and lower signal quality resulting from the use of vias in relatively thick circuit boards or in circuit boards carrying signals of relatively high frequency. The circuit board includes a through-hole in the circuit board substrate for carrying a conductive via stub, the stub having an inherent stub characteristic; and a compensation element, such as a surface mount capacitor, positioned on the substrate such that when the stub is carried by the through-hole the inherent stub characteristic is adjusted to define a compensated stub characteristic.
