An electronic device may include a connector having a connector body and conductive pins extending outwardly from the connector body, and a circuit board having a dielectric layer, and spaced apart female contacts extending therein. Each female contact may include a conductive tubular via, a core within the conductive tubular via, and a conductive cup having a lower end abutting and joined to the conductive tubular via and an upper end defining a recess receiving a corresponding conductive pin of the connector. The conductive cup may have an outer diameter greater than an outer diameter of the conductive tubular via.
