The metal interconnect material is selectively positioned on surface contact points of correspondingly aligned plated through holes on the adjacent printed circuit boards. The stacked printed circuit boards and intermediate metal interconnect material are laminated, thereby sintering the metal interconnect material and the surface contact points of the plated through holes to form electrical interconnects between plated through holes on adjacent printed circuit boards. The metal interconnect material is preferably the same as the plating material used to plate the through holes, such as copper.

A modular electrical system for controlling a liquid crystal display (LCD) contained within a chassis. The system may include a backplane in communication with a power module and video module through connectors on the back plane and respective connectors on the modules. The system may also include a timing and control board (TCON) that is in communication with the backplane via conduction lines that are provided to carry power, video signals, etc., to the TCON. Guides may be provided to ensure proper alignment of the power module and video module with the backplane. In some embodiments, the power module and video module may include input and output connectors that facilitate connection of multiple displays in a daisy chain fashion.

A split backplane for a telecommunication, networking, or computing device includes a power backplane comprising power connectors; a signal backplane comprising signal connectors, wherein the signal backplane is separate from the power backplane, and wherein one or more modules are adapted to selectively connect to the power connectors and the signal connectors simultaneously; and an alignment bar connected between the power backplane and the signal backplane for alignment and stiffening of the power backplane and the signal backplane together for signal integrity and to prevent connector pins from bending or failing between the one or more modules, the power connectors, and the signal connectors.
