Electronic device with multi-diameter female contacts and related methods

A method of making a circuit board to be coupled to a connector comprising a connector body and a plurality of conductive pins extending outwardly from the connector body, the method comprising:

• forming a plurality of passageways in a dielectric layer from a topside of the dielectric layer to a backside opposite the topside;
• plating a first conductive layer within the plurality of passageways;
• forming a core within the plurality of passageways to define a plurality of conductive tubular vias;
• drilling an uppermost portion of the plurality of conductive tubular vias to define a corresponding plurality of enlarged passageways above the plurality of conductive tubular vias;
• plating a second conductive layer within the plurality of enlarged passageways to provide a corresponding plurality of spaced apart female contacts, each female contact comprising a conductive cup having a lower end abutting and directly joined to a respective conductive tubular via and an upper end defining a recess to receive a corresponding conductive pin of the connector, the conductive cup having an outer diameter greater than an outer diameter of the respective conductive tubular via;
• and
• depositing solder within the recess of each conductive cup to surround the corresponding conductive pin.
