Techniques and mechanisms for coupling packaged devices with a socket device. In an embodiment, the socket device comprises a socket body structure and conductors extending therethrough. A pitch of the conductors is in a range of between 0.1 millimeters (mm) and 3 mm. First and second metallization structures also extend, respectively, from opposite respective sides of the socket body structure. In the socket body structure, a conductive shield structure, electrically coupled to the first and second metallization structures, substantially extends around one of the conductors. For each of the first and second metallization structures, a vertical span of the metallization structure is in a range of between 0.05 mm and 2.0 mm, a portion of a side of the metallization structure forms a respective corrugation structure, and a horizontal span of the portion is at least 5% of the vertical span of the metallization structure.
