摘要:
A multilayer ceramic capacitor includes flat-shaped inner electrodes that are laminated. An interposer includes an insulating substrate that is larger than contours of the multilayer ceramic capacitor. A first mounting electrode that mounts the multilayer ceramic capacitor is located on a first principal surface of the insulating substrate, and a first external connection electrode for connection to an external circuit board located on a second principal surface. The multilayer ceramic capacitor is mounted onto the interposer in such a way that the principal surfaces of the inner electrodes are parallel or substantially parallel to the principal surface of the interposer, that is, the first and second principal surfaces of the insulating substrate.

A surface mount electrical interconnect adapted to provide an interface between solder balls on a BGA device and a PCB. A socket substrate is provided with a first surface, a second surface, and a plurality of openings sized and configured to receive the solder balls on the BGA device. A plurality of electrically conductive contact tabs are attached to the socket substrate so that contact tips on the contact tabs extend into the openings. The contact tips electrically couple with the BGA device when the solder balls are positioned in the openings. Vias electrically couple the contact tabs to contact pads located proximate the second surface of the socket substrate. Solder balls are bonded to the contact pads to electrically and mechanically couple the electrical interconnect to the PCB.
