Claim:
1. An apparatus, comprising: a printed circuit board (PCB) having a recess in an outer surface of the PCB, the PCB including a first circuit line having a first portion exposed within the recess and a second portion exposed within the recess, the first circuit line being devoid of electrical contact with vias, the PCB including a second circuit line having a first portion exposed within the recess and a second portion exposed within the recess, the second circuit line being devoid of electrical contact with vias; a first component disposed within the recess and connected to the first portion of the first circuit line and the second portion of the first circuit line; and a second component disposed within the recess and connected to the first portion of the second circuit line and the second portion of the second circuit line, the first component and the second component collectively defining a differential pair, a characteristic impedance mismatch associated with at least one of the first circuit line or the second circuit line being mitigated based on the first circuit line and the second circuit line being devoid of electrical contact with the vias, a first portion of the PCB defining the recess being sized to receive the first component and a size of the second component, a second portion of the PCB mutually exclusive from the first portion of the PCB and having a plurality of ground vias that provide electromagnetic interference shielding for a circuit line in electrical contact with at least one ground via from the plurality of ground vias, a component density of the first portion of the PCB being greater than a component density of the second portion of the PCB.
