Methods and apparatus for accessing a high speed signal routed on a conductive trace on an internal layer of a printed circuit board (PCB) using high density interconnect (HDI technology) are provided. The conductive trace may be coupled to a microvia (&#x3bc;Via) having a conductive dome disposed above the outer layer pad of the &#x3bc;Via. In-circuit test (ICT) fixtures or high speed test probes may interface with the conductive dome to test the high speed signal with decreased reflection loss and other parasitic effects when compared to conventional test points utilizing plated through-hole (PTH) technology.
